    Pretty neat!

  2. edensrichard (verified owner)

    Next level vaping. Precise temp control, batt level display, plugs into phone charger, and more, plus it hits great. This thing is pretty slick. I highly recommend.

  6. RobCo (verified owner)

    I liked the original Flip, but this Flip Ultra has it all. I especially appreciate the digital readout of battery power left. The auto on-off feature when you “flip” the cartridge is also an improvement over having to turn on-off with 5 presses.

    • O2VAPE

      Thanks so much! FYI the FLip Platinum has the auto on auto off as well but you have the latest and greatest!

  7. danrtheman (verified owner)

    This is the holy grail of 510 batteries. It has everything you could ever want in a battery, including precise temperature settings and an auto on/off feature. My only complaint is that after about a week of use, the rubber coating began to peel. I’ve been using it for three weeks, and the coating is about 1/4 gone. I hope the battery will look better once all of the rubber coating peels off.

    • O2VAPE

      Hi Dan, Thanks for the great review and we have already sent a new one out to you! Sorry you had that experience you jut got a bum one as far as the coating.

  8. Taylor O. (verified owner)

    Been an Flip Platinum user since 2018. I love the improvements with the Ultra, especially the lock and improved latch. Now the cartridge stays protected and doesn’t open accidentally in my pocket anymore. Thanks for listening to user feedback. This is a great product.

    • O2VAPE

      Hey Taylor! So glad you like it we love it too! And yes we always welcome feedback 🙂

  9. yeahdude (verified owner)

    I only review things if it’s so bad I can’t justify the cost or if it’s so good it blows me out of the water: I really can’t believe how awesome this is.

    -Better and more consistent delivery than my PCKT One Plus. Had to RMA my POP for a cart sensing issue and the thing is still occasionally hit-or-miss despite regular cleaning and troubleshooting.
    -It has the benefit of dual charging ports which felt gimmicky at first, but is really convenient as hell.
    -Auto on/off is a game changer. It’s insane how awesome this is. No accidental activation or flip out of the cart in your pocket as well as the new locking feature.

    My only suggestion would be an inhale-activated draw mode for ease of use for those with arthritic conditions, but I still love me a button-operated vape: no issues with it potentially not sensing the cartridge, or with people for whom lung strength is a concern but medical marijuana is helpful!

    Overall, this is now my go-to and will be my most used vape until a new one is released, this one breaks and I have to use the warranty, or a better one comes out (lmao, good luck). Great job and thank you.

    • O2VAPE

      Thank you so much and so glad you like it !

  10. Matt K. (verified owner)

    I was a Platinum user. It had some faults that the Ultra fixes and more.

    – much better battery life
    – charging experience is much better, love that I can use my iphone cable
    – the auto on/off is improved, don’t have to close it to turn it off.
    – the lock mechanism is the best yet. love hearing it click when it closes. The extra locking feature is just a bonus

    – battery does get pretty hot when charging.

    I haven’t found a use for me personally for the puff counter

    • O2VAPE

      Hey Matt, Thanks for that and so glad you love it we do too! Just to let you know the Platinum has the same auto / on as the new ULTA once you close the cart back into the unit it is off 🙂 Flip it up it’s on ! As far as the unit getting warm please keep an eye on that, as that is the first we have heard of this issue. If needed remember you are covered by our lifetime warranty 🙂 Thanks and have a vape filled day!

  11. Terrance H. (verified owner)

    Great device, you get real quality here.

    • O2VAPE

      Thank you Terrance! So glad you like it 🙂 VAPE ON !

  12. Ben B (verified owner)

    By far the best vape battery I’ve ever used. Love all of the features that it has. Only thing that I personally don’t exactly enjoy about this battery is the absence of a pre-heat feature. Other than that, this thing is perfect. I’ve recommended this battery to all my vaping buddies. 🙂

    • O2VAPE

      Hi Ben, Thanks so much for that ! Do keep in mind if you want to preheat the cart just hold down the button for a few seconds and you can warm your cart up 🙂 Thanks again!

  13. Scott M. (verified owner)

    The best 510 vape battery, Church cart’s fit but won’t flip open because Church carts are the only one that has been almost to large for the flip ultra.

  14. Mike M. (verified owner)

    Anyone that has been using 510 threaded batteries for more than a year or two has undoubtedly experienced these pain points:

    – The majority of batteries on the market appear to be the same rebranded Chinese goods
    – Extremely high failure rates due to low quality batteries or contact plates decoupling
    – Warranties that are either very short, deceptive or impossible to file claims for
    – Easy to lose and misplace (largely my own fault, partly a result of form factor)

    In 2018 I purchased a 2-pack of O2vape Vari-vapes and found them to be very solid products. After a couple months, the contact plate on one of the batteries came off as I was removing the cartridge and I filed a warranty claim. I received a very friendly response from support along with some great practical advice on preventing the same issue in the future (beware of leaky cartridges!) and the item was replaced as promised. A year later, however, I’ve managed to lose both of these batteries to no fault of O2vape.

    Needless to say, I was ready to find a 510 battery that would last longer than a year and wouldn’t get lost as easily. So I bit the bullet and decided to invest in a Flip Ultra and here are my impressions after about a week:

    – Top notch build quality
    – The display is very useful for dialing in voltage, seeing battery life and it just looks nice
    – With children in my house, the locking mechanism gives me extra piece of mind
    – The weight & balance feels great in your hand
    – Dual charging is novel and appreciated

    – Replace either charging port with USB-C
    – Add a pre-heat/warming feature

    So far I am very pleased with this purchase. O2vape earned my repeat business after a painless warranty claim and I’m glad I went with them again. I highly recommend this product!

    • O2VAPE

      Hi Mike, Thank you so much for the kind words and review of our product! We chose the lightning port because they have not gone to USBC yet for phones! Do keep in mind you can do a preheat by simply holding the button down for a few seconds. Try not to loose this one LOL Thanks again and Have a vape filled day !

  15. Dan (verified owner)

    Just bought to replace the first version. Which still works fine I might add. Like others I am taking the time to review because it’s just so awesome. New added features perfected it. Highly recommend.

  16. Omar (verified owner)

    This is my first vape pen purchase (I’ve tried both button and buttonless). Love flip auto on/off feature, long battery life, and built-in charging ports for both USB and lightning (USB C would be better though). Very pleased.

  17. Senita (verified owner)

    Awesome device! I have used the 5-press-on/off batteries, the button-less pens, and the disposable pens. This is hands-down the best vape pen I’ve used. I don’t have to worry about it going off in my pocket or purse. I feels good in my hand. I really, really like the variable voltage settings! That’s my favorite part! I can quickly control level of the hit.

    I have only 2 concerns. The battery doesn’t last nearly as long as I would like. I charged the pen before I used it for the first time, and it doesn’t last a full 18-hours. My other pens hold a charge for 2-3 days max. The other concern I have is that cartridge can get very hot when I use it at a 3.0v or higher. The tip gets hot enough that I’m concerned about burning my lips. Even with these concerns, it’s still my favorite pen to use!

    • O2VAPE

      Hello, Thank you so much for the nice review ! As far as your concerns, it sounds like that in spite of the good things you may have gotten a bum one 🙁 Most people are reporting days of use and no issues with it getting warm at all please contact us for a replacement 🙂

  18. Andy V. (verified owner)

    To start this off I already owned a Flip Platinum Edition and was already very content with that however, after seeing this new one I decided to save up for when I can make my next impulse buy and I Can say it was worth it! it hits extremely smooth and just aesthetically pleasing to look at! I would recommend it if you decide to vape a lot and want really good quality!

  19. Ryan (verified owner)

    I’ve been using this device for a month now, and yes, this is my first 510 battery, so I don’t have a lot to compare it to. All I know is mine is the sweetest first 510 battery ever. Excellent vapor quality at nearly every voltage setting. As stealthy as any old key fob. Unlike another reviewer, I’ve had no problem with battery life or mouthpieces getting too hot. My puff counter is at 410 and I’ve charged it twice (without it ever dying on me; average 3.8 volt draw). I did have to contact their customer service when the screen threw a short circuit message at me. An employee responded within an hour and offered their professional advice. Turns out one of my carts is weird (paper clip to the rescue) and voila, all fixed! No other cart has caused a problem before or since. Regardless, excellent customer service! Ooh I almost forgot to mention the charging options. THE CHARGING OPTIONS!!! Love. I’m curious what the next iteration will bring because the ultra already has everything I could want. Swiss army 510 battery? Oh yes make that.

  20. Logan (verified owner)

    Best pen I’ve ever used. The materials and shape doesn’t make it feel cheap at all. Totally worth the money!!

    • O2VAPE

      Thank yo so much Logan! Spread the word to your friends!

  21. Chris B. (verified owner)

    I’ve been through several types of vape pens and I have to say, this one is definitely my #1 go-to choice now. Brilliant design!

    • O2VAPE

      Thanks so much Chris! We think so too! 🙂 Spread the word !

  22. Ellen T. (verified owner)

    This is the nicest 510 battery I’ve ever used. I have gone through countless batteries over the last few years. This far surpasses anything.

    I love the flip feature, with the lock switch to keep it from deploying. I love the display and the temp control.

  23. Brent McKinnon (verified owner)

    Best 510 battery unit I have come across and I have gone through at least a dozen other brands. Battery life is great. Convince and stealth factor fantastic. Only complaint is the rubber unit coating peeling within a weeks use. Lot of in and out of the pocket I guess. Still highly recommended. Maybe future models will have this small issue resolved.

    • O2VAPE

      Hi, Thanks so much!! Sorry that happened and that has not been a issue and you do have a warranty so contact us 🙂

  24. JAMES E. (verified owner)

    Love my Flip. I purchased 1 about 2 months ago and it was having some issues after about 400 draws I called O2 talked to Seth awesome dude was very helpful we tried some troubleshooting but didn’t work they sent me a new one with no hassle after about 2 weeks with my new one I dropped it in my drink at a bar of course its not dunk proof but I loved it so much I ordered a new one next day and is working great I recommend this product and the company stands behind there products and is great to work with I have purchased there Dryonic 2 as well I don’t use it as often as my Flip but is also a good quality product. I always do a lot of research with everything I purchase and if your looking for a great cartridge battery this is the one.

  25. Nathan H. (verified owner)

    I am so glad I found the Flip Ultra, it’s the best Vape Pen on the market. I like the versatility of either a USB or Thunderbolt charging option and the voltage range allows you to get all the flavor from your cart that you could ever want. My previous pens that had a button, I would always forget to turn them off and would burn my cartridge while in my pocket. The automatic on/off feature fixes this for me. The video display is really awesome because of the battery indicator as well. It really is a great product and if you are in the market for a new Vape Pen, you won’t be disappointed with your purchase.

    • O2VAPE

      Thank you Nathan! So glad you are happy with your purchase!

  26. Bailey A. (verified owner)

    Works really well. I love all the information on the display. So far no issues with cart compatibility. I’m finding between 3.2-3.6V works the best for me.

  27. Vincent S. (verified owner)

    My first impressions opening the box was it looked good and felt great in my hand. Then I tried it and OMG it works unbelievably the feature to adjust the voltage works great you can choose to get small or big hits and let me tell you it can hit like a beast when you turn it up. Overall this has become my favorite vaping device for essential oils and I own quite a few some much more expensive than this one. I will certainly be purchasing another and already have a few friends that are ordering ones for them selves. I paired this device with the Vari-Flow Cartridges: 510 thread sold on this site and they are fantastic together, couldn’t be happier with this purchase.

    • O2VAPE

      Why thank you so much Vincent!!

    I should really leave this product 4 Stars because the black material is already peeling at all corners and edges after just two weeks of ownership. Even with that however, I just couldn’t bring myself to do it. It’s the best Vape I’ve used. It works like a charm, I get much more out of my cartridges, and it feels soooo good in my hand lol. It’s already earned a full-time spot in the pocket when I leave the house 😋.

  34. Beth (verified owner)

    Sleek and convenient. Way better than the pen battery I had previously. It’s super easy to use right away. The flip feature is so fun. Even got one for a friend. They love it as well.

  36. Nicole (verified owner)

    I have been using my new FlipUltra for a while and it is by far the best on the market. I am a fairly new user but my very seasoned smoker partner is even impressed, which is no easy feat! He’s very much an “old dogs cant learn new tricks” type of man where he is very comfortable and happy using the classics.

    The description is very spot on. You will not be disappointed with any of the features available on this battery. My favorite part, though, is the discretion. It easily blends in and looks just like part of your every day carry items. I attached mine to a spiral wrist band with a cigarette clip keychain, lighter leash and lighter, and my locked safe keys so that I have all of my smoking necessities close by and always on hand. It literally just looks like a set of keys.

    The easy flip open and close is great. I tend to get over-excited sometimes, though, and forget to let it actually turn it on before taking a hit lol so beware of this. Give it at least half a second to get going.

    The puff counter is great. I haven’t needed to use this but it is great to monitor how much you’re smoking in a day.

    My second favorite feature is the battery life display. I can’t tell you the number of pens that have failed me just because I had no clue my battery was low.

    Last, this pen fits GREAT in any size hand. I have teeny tiny hands and my boyfriend has extremely large hands (he’s 6’5″). Both of us love the weight and actual size of this product. My hand easily wraps all the way around, concealing it even more.

    • O2VAPE

      Hi Nicole! Thank you so much ! We are so glad you like it and again thanks for the great feedback 🙂

  37. JB (verified owner)

    Awesome product…. I’ve tried several different brands of the key fob battery and after going through probably 6 of them over the past year, I decided to pay the extra this product cost and it is well worth the money… not to mention the lifetime warranty the company offers makes it even more worthwhile. The product is solid and has a lock, which is great because I have broken 2 carts from it popping up on my old ones while they were in my pocket… Also love that its digital and I can adjust the temperature more precisely. I recommend this product and it IS worth the extra you pay for it!!

    • O2VAPE

      Thanks so much JB!! We think it is the best one out there as well! ENJOY!!!

  38. Arnold (verified owner)

    I’ve had a Flip Platinum for a couple of years and have always loved it. The concept, design, and build quality are superb. The only thing I thought it might benefit from was a bigger battery. On an impulse stirred by a coupon, I ordered the Flip Ultra. AS good as the Platinum is, the Ultra is a great improvement! Slightly smaller, it feels great in the hand. The “Flip” mechanism also feels more solid and secure. I thought I’d miss the built in USB cable but always wondered if it broke, then what? I don’t mind using the separate cable especially with the improved battery size. Of course, the digital display makes a significant difference especially if you’re going out (like to a concert) and you need to make sure it’s fully charged! It also allows greater and more precise voltage selection. I’m still playing with it.
    Given the moderate price difference….Go For It, you won’t be disappointed!! Plus, there’s the “Wow” Factor!!

  54. Juan C. (verified owner)

    I am a huge fan of this product. The fact that I can use my iPhone charger is a game changer for those times where you need a quick charge when you’re out and about. I also like the display screen with the battery life and the amount of times you’ve hit the pen. I’ve had this pen for four months and glad I made the purchase. Battery life is good, with moderate use it takes about a week and a few days before I have to charge it. But my definition of moderate may be different from someone else’s. The only issue I have is as one customer stated the rubber coating of my device is peeling off. But would recommend.

    • O2VAPE

      Thank you Juan! Please contact us about the peeling issue and we will take care of that for you !

  55. Drew (verified owner)

    I had an old vape pen I had purchased from O2 a few years back. I recently replace my vape pen with with the Flip Ultra and wished I would have done it sooner. You can charge the unit with an iPhone charger which is fantastic because I usually don’t carry micro usb chargers with me at all times. The display is clear and helps you identify when you need a charge and the appropriate voltage setting. The flip lock works well and is a great feature. Would buy another one tomorrow!!!!

    I have used the original Flip for a long time and loved it, then it fell off the roof and broke. I saw the Flip Ultra and said that is what I want. The lock takes care of the opening in the pocket issue, the digital readout is great,and it works great. This is the perfect all around vape!

  57. Smoking for over 40 years (verified owner)

    I just got this item in the mail today and it weighs almost identical to my “other brand” of 650mah variable voltage battery, but performs light years ahead of every other brand I have tried. It arrived about 98% percent charged (thank you) so it only took a few minutes to fully charge via the Lightning port (nice touch btw). Keep the Lightning port as Lightning cables are cheap and plentiful. Box was sealed with a Official O2 Holographic seal, another nice touch. I expected the instructions to be semi complicated, but nope they were simply and easy. The display is nice and bright. I like how the display dims after 15 seconds when it goes into power save mode, another nice touch. A well thought out design for sure. I’m digging it so far and I have used “many” different brands of batteries for years now, but this one is way ahead of the pack and this one is by far my new favorite! 😉

    • O2VAPE

      WOW!! Thanks so much ! Yes, we love it too! It’s my personal favorite as well! Enjoy!

    O2Vape is an excellent Brand. I had been religiously buying the Platinum Flip for 3 years & never had any complaints. I purchased anywhere from 7-10 pens over the course of 3 years. If I ever had an issue with 1 all I would do is reach out to Client relations & they would take care of getting me a replacement. They have always honored & stood by their “Lifetime Guarantee”
    I have now moved onto the Flip Ultra & I have purchased 2 in the last 6 months. I love this pen & I still use the Platinum as well. O2Vape has the best customer service I have ever experienced. I would never purchase any other Brand.

    A solidly built, and convenient battery, hits great!

  60. Dave (verified owner)

    So you’re reading reviews to help ya decide? The short answer, Yes. And since everyone wants to know issues before getting to accolades, I only have one minor gripe and that’s my bad timing because about 3 days after I bought mine for $54.95 I get a Sale email which shows it on sale for $41.95. Thems the breaks, some days ya catch every green light and some days ya catch all the reds, ha! When I received my new Flip Ultra I waited until I had a worthy cart to break it in. So I had a few days to check it out a little more. Ya know how sometimes as soon as you pick something up it feels solid and well-built? Well, that’s the Flip Ultra. It has great tactile feel, there is NO slop in its construction, the buttons feel ‘just right’ for their respective functions, the screen is very easy to read, the “flip” has been likened to a switchblade and I wholeheartedly agree, and the battery deserves its own kudos. Ahh the battery, so far I have charged this baby ONCE and I’m STILL showing 2 bars! I loaded that new (Eureka) cart onto my Flip Ultra 2 weeks ago, been hitting it every evening, 2 weekends hitting it with my lady and it’s still chuggin along quite nicely. YMMV based on settings I’m sure, but still, I’d say it’s a safe bet you’d be pleased with the battery life. The locking feature on the back is brilliant, so simple but so smart. It opened on me once because “I” forgot to lock it and the one time was enough for me to appreciate the Lock feature on the Flip Ultra even more. The black surface is like that upscale ‘rubber’ feel we’ve all grown to like regardless of application so it won’t ‘slip’ out of your hand/fingers if they’re wet. Again, smart. I REALLY like that I have two different ports to charge it so I can use my iPhone cable to charge it, no extra cable needed. Smart & smart. This Flip Ultra simply looks, feels, functions, and hits, like a thing of quality. Probably because it is. I happily recommend this vape. I dig this thing enough that I’ll be getting one for my lady since she LOVES it, I think it’s become another erogenous zone for her, and so she’ll stop taking mine. Ha!
    Seriously, you won’t be disappointed, so go buy & enjoy.

    O2Vape is by far the best Brand I have ever bought a product from. I am happy with every purchase I have made with O2Vape. I have purchased at least 10 Flip batteries, dating back to the original (not variable temp controlled) – I loved it…A few months later they released the Flip “Platinum” I purchased at least 6 of these over the course of 1 year (Give or take) – Then when the Flip “Ultra” was released I purchased 3 in a 2 moth span I loved it so much. I prefer to have a Battery in multiple places so I don’t need to carry them outside or in my pocket too much. If I ever had an issue with a battery suddenly not working – O2Vape sent me a replacement if they could not repair…Every single time!
    In my opinion consumers always remember & review Customer service at any business. If you have bad customer service you hear about it in every review written. I am only stating this because O2Vape has the best “Customer Service” I have ever had the pleasure of working with. I am O2Vapes Happiest Customer Ever. I have not 1 bad thing to say about anything.
    Only other thing I will mention is the Customer service / IT team @ O2Vape – I have had the pleasure of working with 3 different reps they were all amazing, went above & beyond each time I reached out. I can remember 1 time I returned a Battery that stopped working & in a matter of 4 days I had a new 1 in my mailbox!
    I will always be faithful to O2Vape -I have never purchased a Battery from any other Brand & I will never!
    Thanks you So much for all you do, O2Vape!!

    This thing is excellent. From the second you open the box you can tell this battery is quality. Ridiculous battery life, very customizable temperature settings, puff counter, and locking back so it doesn’t turn on in your pocket. I absolutely love it. I haven’t charged it yet and I’m on puff 228. Expensive, but worth it.

    • O2VAPE

      Thanks Justin! So happy you love it stay safe and VAPE ON!

    Have the Platinum as well and love it since it has a built in charging cord. However, the Ultra might be a step above because it can be charged with either micro USB or the Apple lightning cable which is super convenient. Also love the size and the digital display which includes battery indicator, toke count, and power output. Very pleased with this little guy.

    • O2VAPE

      Thank you for the review and your business!

  70. Lurk (verified owner)

    The BEST 510 threaded “mod box” I’ve ever owned, I like to keep it at 3.2-3.5 to make my carts last but when feeling chippy I crank it to max (4.8) & it hits like a champ! I kept seeing reviews of others saying to make it Usb-C, I’ve been an early adopter to usb c & I cant for the life of me know why you’d want that over lightning (esp with a 5v brick) if you use an Iphone the lightning is always with you (duh) it charges just as quick as usbc with such a small device. The LED is nice n bright, puff counter is cool but always find myself shamelessly reseting it. The powerful quality “Flip” and overall Matte feel in the hand makes this the most seamless wonderfully powered battery on the market! – Look no further…you finally found IT!

  75. Dylan James Confer (verified owner)

    The only reason I didn’t give it a 5 star is because I know the threads on a lot of 510 carts are cheaply made by the thousands with subpar quality standards and they are going to eventually strip the threads of the device I wish it had a little more weight so you can feel it in your pocket that’s the only thing I can see causing trouble and it should have a draw feature for people who cant press buttons that’s my only negative….. I love the loop so you can add a lanyard I went from an old-school innoken mvp 2.0 lol to this and basically this design addressed all the problems with my old unit that’s why I decided on this unit and it holds 1.5 1.3 ml carts as well if your not used to standard 1.0 ml carts I’m just hoping my threads don’t strip out but this product at the price point with a warranty you cant beat it everyone has said where did you get that how can I get one is there a knock off I said no only one lol I’m actually going through the wholesale process I believe in the product and it addresses every issue i can come up with other then people with heavy bad arthritis might not be able to push the fire flip or voltage control very easily (i work with elderly as a cna) and people that need really need the benefits of good cbd/thc oils might not be able to use this unit I tried getting this unit to fail and I couldn’t left it in the mud got it a lil dirty used to cheap carts I was trying to see its limit I froze it left it outside in garage all night cuz sometimes in our haste we forget to stash our stuff and the 3 way charging is awesome and you guys send a charger a lot of companies charge you extra I must have looked at over 500 units from fob designs to stick battery to pod designs and this is by far the best I was tired of buying a new device every 2 months because it crapped out or came apart this is built very well and veteran owned lets keep these VETS taken care of maybe as a suggestion offer a rubber case for a fee and maybe send a lanyard with it and it would be 11/10 for me but i rate this as is at 9/10 best vape device i have found and u can taste the terpenes finally a device that just doesn’t give you hot tasteless hits its full of flavor

  76. Kiana T. (verified owner)

    This is my first ever vape, so I don’t have anything to compare it to. Lol. But I love it! It’s small and convenient to carry. I love that it can be locked so the cart doesn’t randomly pop out. It’s super cute and easy to use. The battery life is great. I like that it has a little screen that counts hits, shows how much battery is left and lets you easily adjust the voltage. Also the auto on/off is great! So perfect and definitely worth it!

I looked all over for the right pen and finally decided on this. SO HAPPY I did. Love that it closes and looks like a car key. The auto shut off makes sure it never fires while in your pocket. Feels good in you hand and again, perfect draws every time! THANK YOU o2! Best. Pen. Ever!

    I just received my Flip Ultra yesterday and I was upgrading from a very basic $20 “LoKey” fob style battery. The flip ultra definitely addressed my concerns with the cheap off-brand version. It turns off automatically when folded closed, no more accidental pocket vaping. The flip mechanism has a lock, no more getting stuck in small pockets when opened unintentionally. It was very nice to see optional USB C charging. Also, my last battery had only 3 preset temps it was either a nice low temp or hot and hurty! The Flip Ultra gave me a wider Temp range and I love being able to adjust in small increments providing any temp vaping you are comfortable with (paired with Buddy Diamonds full gram cart).

    First I want to mention this is the best “vape” company I have ever had the pleasure of speaking to. The device is clearly next level (look at the other reviews), but I have called customer support at least 5 times to discuss their products, and it feels like I’m talking to a life long friend every time. Lifetime warranty, best carts on the market, and charges with lightning port. Why doesn’t everyone buy these? You guys make another Michigander proud.

    A simply fabulous vape pen. Love the flip-out design, which makes it easy and discreet to carry around in your pocket. It has a light application of soft-touch rubberized coating, which gives it a nice feel–as other reviewers have noted, the thing just feels like a quality device in your hand. The digital status screen means you always know your exact voltage setting (how did I ever live without this?) The battery life is amazing, too.

    Is it expensive? Yeah. But if you’re looking for the Porsche of vape pen, this is it.

    Do not usually take time out to write reviews but this little guy is excellent. It is tight and compact with all the little necessities needed in such a product. Controls over the voltage, battery life indicator and a puff counter telling you how many times it was used SHOULD be include with all products like this but are not. Even has multiple charge ports. The flip lock so no accidental openings is also fantastic for us outdoor active types. And a great price!

    Albeit mine is only a couple of weeks old, it works better than other pens I’ve owned. This has a great design that is sturdy and works every time.

    I had a flip, it still works well. My wife is using that. She loves it. I decided to upgrade for my birthday, and I’m very impressed.

    It’s very well built and doesn’t feel cheap at all. The controls are simple and intuitive. I learned them in 15 seconds.

    The body of the unit protects your cartridge. I sleep with it retracted in my bed with zero issues. The ui is bright and readable. The variable temperate functionality shines as well. Add to that a battery indicator and this is far above industry standards.

    This unit is really worth double the price, but I’m glad o2 isn’t run by mitch mcconnell, because they priced it for everyone, not just the rich.

    Well done. I look forward to future models of the flip series if that is on the table. I value this unit very much.

    If you don’t like having to spend time shopping and doing excessive reading to find the best of something simple; this is your stop. Hopped on google and looked up the best 510 vape. Scrolled a few top 10 articles and this one looked like the right one. Ordered it and the UPS Ground shipping came correct getting it to Philly in two days.
    The two charge ports are great because of the prevalence of the iPhone. Doesn’t matter if you are around team iPhone or team Android. There will always be a charger around.

    The cartridge that comes with it is of admirable quality. I don’t fill my own so it sits in the box unused for the time being. As for the unit; it just works and the voltage goes low enough that you pretty much can’t burn the wick unless you try. The folding mechanism in it is sturdy and the spring has a little kick to it. In your hand or pocket it doesn’t feel like you need to handle it like an egg. Bottom line is it’s worth it.

The only complaint is after about 2 months my rubber coating came off. It’s not a deal breaker though. Sorry for the late review just started checking your website again and thought I would add my review for this. Thanks for a great product guys

      Hi Cameron, Thanks so much for the review and sorry to hear about the coating … You do have a warranty you can always contact us 🙂 VAPE ON!

    I’ve tried so many vaporizers. The last I tried was pckt which like most others pretty much dies fast if you’re a heavy user and also stops hitting good when the battery isn’t full. The flip hits the same from start to finish and lasts longer than others. it works great with pure distillate.

    • Dana E. Shoched

      Thank you so much Ron, enjoy!

    Nice and compact. Holds a charge for days. Love the single push button. Great product!

      Thank you Ben! Live long and VAPE ON!

    Great build quality. The battery indicator is a godsend. The lock ensures that the cart doesn’t accidentally flip out and break. Overall it is a fantastic product

    • Dana E. Shoched

      Thanks Tony !! VAPE ON!

    I love it. Had issues with my first one but it was promptly replaced. It’s a nice device. Well worth the money!

  130. Michael (verified owner)

    Here’s my honest review
    If you’re like me, I try not to spend the extra money with something I can buy cheap at my local store but if I put the money out I want something of quality. After doing some research I ended up here. I have to say this product is the way to go I got the most bang for my buck. I would go with the flip ultra. The sleek design makes it not fill my pockets (I carry a lot for my wife) I honestly love the readable digital voltage. I honestly thought it wouldn’t be readable after constantly using my ultra flip I haven’t seen one different in wear. And also they’re a veteran owned business how could you not go wrong with spending the little extra cash! The only thing I found abit wrong maybe it’s just the way I charge it but once I hit full battery for some reason a bar of the battery is gone soon as I take it off the charger. But other than that if I charge it for a full night it last me more than a week of use. Thanks for the purchase! Will be deff recommending to others

    • Dana E. Shoched (verified owner)

      Thank you so much Michael and welcome to the O2 family!! If you are still having issues please reach out for a warranty!

    If you like a flip vape there isn’t a better one anywhere else. On my third currently, usually get about 6-8 months out of mine.

      Hi Brain, Thanks so much and you can always call us and use he lifetime warranty 🙂

    The best battery on the market, IMO. I can fine tune my temp to exactly what I want, no more hacking a lung.

    Thank you!

      Thanks Mike! VAPE ON!

    I recently purchased the Flip Ultra vape battery and could not be happier with this product. This vape battery has so many innovative features and is simple to use. This is the third battery I have purchased from O2vape and while pleased with all three, the Flip Ultra is by far the most impressive and easy to use. I highly recommend all their products but also want to emphasize that the company’s service and support is also excellent. I have had several small issues in the past but O2Vape has quickly and totally resolved all matters to my complete satisfaction. Best in the business!!!

    • Dana E. Shoched (verified owner)

      Thank you so much Dave! Happy to have you as part of the O2 family! VAPE ON!!

  138. Aaren A. (verified owner)

    Great vape, battery lasts forever. Love the locking feature, it’s what my old flip vape lacked. The puff counter is neat too. I wish there was a preheat function though, this vape could benefit from it.

    • Dana E. Shoched (verified owner)

      Thanks Aaren, we will keep that in mind although we have had pens with preheat we found more people had issues with them so we did not add this feature this time.

  139. James (verified owner)

    It’s so much better than the original design. The Flip Ultra fixed every problem I had with the original. 10/10

    • Dana E. Shoched (verified owner)

      Thank you James! Enjoy..

  140. Terri G. (verified owner)

    Absolutely love it! I have asthma so I can’t smoke it. I use the vape pens. This is the time I’ve used something and can still breathe. I love that I can adjust it depending on how I’m doing that day.

    • Dana E. Shoched (verified owner)

      Thank you so much Terri! We are so happy you are able to use and not have it effect your asthma! Welcome to the family!

  141. Patrick (verified owner)

    This is just about the perfect device for vaping on the go. It is extremely well thought-out. It has every feature you need and really none that you don’t. Love that it has a lighting port as well as micro USB. The screen appears to be OLED and is bright, simple, and crisp. It has a nice smell out of the box, and even the included micro usb cable is good quality!

    I keep coming back to O2VAPE. No one is perfect, but these guys are the best in the business I think, and they keep improving their products. What more could you ask.

    • Dana E. Shoched (verified owner)

      Thanks so much Patrick, welcome to the family and VAPE ON!

  142. Ashlie (verified owner)

    Got two of them. Great quality and work well. Haven’t had any issues.

      Thanks Ashlie!

  143. David B. (verified owner)

    I have usually used automatic pull vapes. This was was my second or third manual pull battery, so closing my pen after each use took some getting used to, but I could never be happier. Adjusting the voltage is a breeze. The inhalation counter rocks and reminds me of my asthma inhalers. Y’all be cool and live life to the fullest.

    • Dana E. Shoched (verified owner)

      Thank you David! Welcome to the family !

  144. Frank P. (verified owner)

    This is by far the nicest device I’ve found for vaping .510 thread cartridges. very solid feeling in hand, variable voltage to get exactly what I need and battery life has been very impressive.

    • Dana E. Shoched (verified owner)

      Thank you Frank! VAPE ON!

  145. Alex W. (verified owner)

    This has hands down been the best mod I’ve used for pre filled carts. I bought my Flip Ultra closer to the start of the new year but now around hit 5713 on the hit counter I’ve run into a “loading check” error that is preventing me from using it.

    • Dana E. Shoched (verified owner)

      Wow that is a lot of hits LOL, Thanks so much if having issues please contact out cust service department as yo have a warranty 🙂

  147. Lynn (verified owner)

    I received my Flip Ultra about two weeks ago and I absolutely love it! I took it on a road trip with me and was surprised how long the charge lasted.

    • Dana E. Shoched (verified owner)

      Thanks Lynn, VAPE ON!

  148. Douglas S. (verified owner)

    Great product! Looks like a key fob instead of those weird long e-cigarettes. I’ve used it over a couple of hundred times and the battery still has a charge. Nice little display screen that makes it easy to see what volts you’re on and it super easy to adjust and use.

    • Dana E. Shoched (verified owner)

      Thank you Douglas! Welcome to the family and enjoy.

  149. Ryan (verified owner)

    Been using my Flip Ultra for a little over 2 weeks now and couldn’t be happier. Having the ability to control the temp as well as see a puff count is a huge bonus. I also like that it doesn’t seem to overburn like the typical vape batteries do. I’ve also tried 4 different 510 thread cartridge batteries, all from different vendors and found that they all work as expected!

    One last thing, I also appreciate that you don’t use your product names on the shipping packages. Being able to be discreet is always a plus!

    • Dana E. Shoched (verified owner)

      Thank you Ryan! So glad you like it and welcome to the family! VAPE ON!

  150. Michael R. (verified owner)

    My favorite mod/battery yet!
    I’ve owned maybe 15 different mods in the last few years and the Flip Ultra is by far my favorite. The flipping action is powerful and locks into each position with authority. A really nice feature often overlooked by the cheaper competing models, it automatically turns on when flipped open and turns off when closed. The manual “lockout” feature gives me piece of mind that it won’t flip open in my pocket unintentionally. The puff counter is a nice bonus to observe the longevity of different products. Voltage is adjustable in 0.1V increments so I can really fine tune the flavor/vapor. Another nice little bonus is that it can be charged with either a regular mini usb we all have tons of, or with an Apple lightning cable. Big battery, small footprint, build quality feels solid in hand. A solid offering from o2vape to be sure. 10/10 recommend.

    • Dana E. Shoched (verified owner)

      WOW!! Thanks so much Michael and welcome to the family!! VAPE ON!

    This is the revolution of Vaping. Has to be hands down one of the greatest batteries I’ve come across yet. And sturdy materials. Feels great in the hand when both open and closed. Has an awesome locking mechanism. Charging is easy and super fast. Definitely worth the buy.

    • Dana E. Shoched (verified owner)

      Thanks Jon, Welcome to the O2 family!

  152. Matty (verified owner)

    I absolutely love this thing. Very well built, great controls, and it’s just cool too.

    If I could make one suggestion it would be, in the next revision, to add a small LED flashlight to it! Sometimes you lose that TV remote when this is in your hand, if you know what I mean.

    • Dana E. Shoched (verified owner)

      BAHAHAHA Matty ! Glad you like it and will keep that in mind for the future generations, until then we sell vape lanyards 🙂

  153. Sandra K. S. (verified owner)

    This pen charges fast and stays charged for longer than anticipated. Small compact size if it’s in the pocket very well. I appreciate the variable heat settings and would recommend this product.

    Best vape on the market hands down.
    Convenient, lightweight, fits in my pocket, & don’t have to click it 5 times to function. Just flip it up and press a button. I also love the ability to regulate voltage, AND the two charging opinions are the icing on the cake!
    Everyone at the local dispensary is jealous.
    Look no further, the is the first & last vape you will ever need.

    I have had my Flip Ultra for a little over 3 months now. I love it! It is perfect for travel or work. The whole reason I am posting this is because I was on here looking at their Ceram-X pen and I am going to buy that as well. I felt compelled to share my experience so far with my Flip Ultra and I believe I will have the same experience once I have the Ceram-x. So all I have to say is keep up the good work O2!

    This is the 2nd time I purchased and bought 2 because I always seem to lose it.
    My all time favorite battery. Been smoking carts for 6 years had hundreds of batteries and this is the best by far!

    Iphone charger is awesome but can we get a type C charger? It is the way of the future!

  167. Jay S. (verified owner)

    This is my first vape battery, and I think I started with a winner. I love the flip out style and the incremental temp control. It seems to have the best features one would expect in a battery. I also need to give a shout out to customer service. I didn’t get my original shipment, and everyone I talked to in customer service was great, and they made sure I got what I ordered. I’m not sure if I’ll need another vape battery any time soon, but if I do, I’ll be visiting O2Vape first!

    • Dana E. Shoched (verified owner)

      Thank you Jay! Welcome to the O2 family!

    Simply a must have if you use carts. Love the puff counter and the battery on the LED. A major issue I have with other companies is I have no way to know where my battery is at and I will leave my home without a charger and be so disappointed when I got to my destination only to have a dead battery. I’m sticking with O2VAPE for my battery needs from now on.

    Excellent. Love that it fires up when you pop it open. Not clicking 5 or 6 times to turn it on is amazing.

  171. Josh (verified owner)

    This is the best 510 vaporizer ever! I love the fact it has a lightning port so I can use my iPhone charger to charge it. The battery life is amazing and lasts many days without charging. The puff counter is an awesome feature and you can choose many voltages for your vaping needs. If your looking for a great 510 battery, look no further! I’ve have many nice comments on my o2 Vape Flip Ultra and pointed them to this site. The price almost seems too low for such a perfect vaporizer as most of my friends thought it would cost an easy $80-100. I can’t say it enough, if you’re looking for a 510 battery, look no further!! You won’t be disappointed!! I LOVE IT!!! Thank y’all so much!!!

    • Dana E. Shoched (verified owner)

      Thank you Josh!! Keep a eye out for a new color possibly coming

  172. PO (verified owner)

    I LOVE this pen!!! It is very easy to use and the compact form factor is so much nicer than the long pens. It auto disables when closed so no more burning pockets, it has a great digital display for battery and a counter for how many times you puff on it. Nice secure feel to the flip up part. It is all metal where it counts and i love the soft feel of the plastic parts. Also good for my pocket is the “over smoking” feature that cuts it off when you’re pulling too long lol. It’s not much bigger than my car fob. Highly recommend this!!! One more thing I forgot to mention is this has charging ports that fit apple or android connections so you can literally just plug into whatever is close by when needed although mine holds an excellent charge.

    • Dana E. Shoched (verified owner)

      Thanks PO !! SO glad you love it and welcome to the O2 Family!

  173. Amanda (verified owner)

    This is an AWESOME vape pen. I will definitely be buying another!!! It draws beautifully and doesn’t make you cough/isn’t harsh like some pens can be. The ability to modify the heat settings is cool though the standard heat settings have worked just fine for me. Highly recommend!!

    • Dana E. Shoched (verified owner)

      Thanks Amanda! Welcome to the family!

  174. Shunta H. (verified owner)

    I’ve tried several different pens over the past few years but the Flip Ultra is my favorite hands down! I appreciate the design and it’s so easy to conceal. It has a nice feel in hand; soft, smooth, not that cheap hard plastic feel like some others. The auto on/off with the “flip” excellent idea, a step up from the 5-clicks – which is ok Im not complaining. The 5-clicks on my woodgrain 3.7XL are nice and smooth and feels good to my thumb 🙂 and that’s comparable to a Chrys 300 srt8 imo a decent powerful car! However, the Filp Ultra is like a Mercedes S65 and that’s verrrryyy niiiiceeee!!!!! Power and luxury my favorite combo! I can’t wait to see what’s next. In the meantime, I’m loving the ultra and have some more back-ups on the way! Thanks O2 team you guys are amazing!

    • Dana E. Shoched (verified owner)

      Wow Thank YOU !!! Shunta that has to be one of my favorite reviews I have seen welcome to the family !!
