  1. Charles R. (verified owner)

    This little lady rocks your socks clean off. It stores and displays your carts in the upright position and does it with style. All functions work as advertised. The variable voltage makes a big difference and each setting provides a different level of cloud and hit, which I imagine helps with oils of different viscosity. I find the lowest setting provides nice hits and conserves oil slightly but the middle setting is just perfect for me. The hits taste and feel amazing. The last setting is great also if you feel like tearing your head off. Be aware that I don’t know if the picture does justice to how small this thing truly is, I’m worried i may lose it. It’s probably about 2/3rds the size of a lighter (adding in the tip of the cartridge).For people wanting discretion about their sessions this is perfect. When I’m hitting it, it looks like I’m picking some food from my l teeth or wiping my lips, if i want it to. No one will know what your doing as this tiny thing disappears in your palm, unless of course you exhale your vape cloud directly in their face. So After that long mouthful of a review , the only con I could come up with could be that the price may seem a little high to some people at $40, but it’s really not if your considering the lifetime warranty action and the fact that they try to fix it for you and rectify the situation if it stops working. Very happy with all o2VAPE products I’ve tried thus far( Vari Vape XL, Nano battery, Vari flow cartridges and Ceram-x wax pen, review on that pen coming soon)

      Thanks so much Charles so glad you are a happy customer! We strive for that ! Remember we have coupons out there to help offset the pricing for people on a tight budget 🙂

    The form factor is what sold me on this device and the performance of it is making it my favorite vape I own. Everything works as advertised and all the different functions are totally adequate for the cartridges this uses. You really don’t know how small this thing is until you get it, and that is the awesome part about this little guy. For what you get for the price this is
    a great small form factor vape.

    Wow! It fits the Large bottom 510 cartridge, I’m impressed with how strong the hit is. Fits my larger Lion cartridge. Stoked!

  5. Adam P

    This was a gift and its great. I was told that this has a real life time warranty. I’m very impressed with the function and design, we shall see about life and warranty but I am hopeful its as impressive as the design and function.

  6. MARK H.

    Fantastic Design ..pair it with the O2 vape cartridge with variable vent system ..and its a serious little evryday carry system for using with high quality thick oils

  7. robobk (verified owner)

    Great battery, small discreet design.
    The pre-heat feature is nice and often overlooked, along with variable voltages.
    Performance and reserve capacity are great as expected.
    Only thing I can say that is not mentioned in the instructions or on the website is the LED changes from red to blue when done charging (was wondering during first charge before use).

  8. John R (verified owner)

    Fantastic unit! The things I love about it are: 1) It’s tiny. 2) It holds your cartridge upright when you’re not using it. 3) You can charge it with a standard USB charger. 4) It’s feature-full with pre-heat and variable voltage. 5) Did I mention that it’s tiny? It’s my new goto portable vape. I just bought another one for the wife.

    • O2VAPE

      Wonderful! Thank you !

  9. kpkva64 (verified owner)

    To steal a line from Dr. No “hits like a brick through a plate glass window” compact and lethal. Tried all levels…first is perfect for me…second is wow…third is good night.

    • O2VAPE

      HAHA! Thanks so glad you like it!

  10. cofree (verified owner)

    Best ever.
    All of my different carts fit perfect on this.
    Even the big co2 carts that trulieve (in florida) uses

  11. Jennifer W. (verified owner)

    The Nano is tiny, yet it rips! I love it. So discreet. My go to battery! This company is A+!! O2VAPE… Thank you AGAIN!!

    • O2VAPE

      Thanks Jennifer !

  12. Heather (verified owner)

    I absolutely love the Nano! It’s perfect. Super small and still rips. The battery life is surprisingly long for the size, I easily go 2 – 3 days without charging. The only warning I can offer is to be sure to turn it off before you put it in your pocket or purse, it will run…you won’t know…it won’t end well. Seriously, you cannot go wrong getting one of Nano of the FLip Platinum.

    • O2VAPE

      Thank you Heather So glad you love them ! Yes, we recommend turning it off before storing in a pocket or purse as stated in the instructions and on the website! Thanks again, enjoy!

  13. Tim

    Damn. Tiny vape packs a big punch! Just received mine and it’s got all the features of the more expensive vapes! Haven’t tested the battery life yet—will circle back and report.

  14. srhlivin (verified owner)

    My wife and I absolutely love this product, and have used it every day since. I’m looking forward to ordering more products in the future, and also sharing with friends and family how great these products are. We are in the process of opening up a new tattoo studio here soon and looking forward to having these products in our studio!

    Keep up the great work, the quality is amazing and the product is amazing. Fast shipping, and I’m sure the owners are just that is amazing!

  15. Ruben (verified owner)

    Best vape out there I love it. Works well even large 510 cartridges fits. I use it everyday whole afternoon and evening and the battery last me 1 week to 2 weeks. CRAZY STUFF!!

  16. doctorrosinrivers

    Stop reading and buy this thing already. I’m in L O V E.

  17. Henry (verified owner)

    Surprisingly powerful. It sports a nice heft for such a tiny object. I wish the high temp setting was 4.3 rather than 4.0, as in the Platinum Flip pen. This is a well-made product.

  18. philsmith1125 (verified owner)

    My review is short but direct…I have nothing to say but ‘good things’ regarding my O2 Vape purchases! After 45 years of buying products like this, O2 Vape has hit a home run with me! Why? just ask Phil

  19. Joel (verified owner)

    Nano, nice and smooth product! Nice features!

  22. Kam kam (verified owner)

    This vape out does its self I have had it for 4 days an not one time did it die,until I went through a whole cart,The nano is very durable i have dropped it a couple times an it protected the cart had no scratches,I recommended this little hitter to everyone who sees it,you may not want to put this much money out on it but it is truly worth it.

    • O2VAPE

      Thank you and VAPE ON!

  23. Adam C. (verified owner)

    Another perfect product from team O2Vape! They always nail it! I specifically use this little guy for my bedside table hitter. If I ever have trouble sleeping, it’s right there, with the oil sitting properly upright and ready to go, no questions asked. I only use O2Vape for a reason! They simply are the best! Keep it up, guys!

    • O2VAPE

      Thanks so much!!

  24. Drewbie (verified owner)

    I ordered a 2-pack of the nano battery! I am so impressed by this micro compact look and it doesn’t show any signs of backing down to any cart I have tried with it! I was waiting for a different company to restock our favorite battery, but now this is our favorite by far! I highly suggest this lil devil out to replace your old stick battery. Thanks All keep making solid products!

    • O2VAPE

      Why thank you so much Drew!

  25. Scott F. (verified owner)

    This is a fantastic and inexpensive battery. It’s my favorite oil vape (and I’ve got a lot). Highly recommend!

    • O2VAPE

      Thanks Scott!

  26. Scott F. (verified owner)

    This really performs as an ultra portable vape. Its pretty fantastic. Worth way more than the price. I am very pleased.

    • O2VAPE

      Thanks Scott!

  27. justin w (verified owner)

    Literally my first mod outside of the beginner BS pen. I was going for discreet, but was kind of concerned about functionality. I Was very very pleased with the size, ergonomics, and charge time. Was definitely a perfect choice.

    • O2VAPE

      Thanks Justin so glad you like it !

  28. Aleesha (verified owner)

    Perfectly compact and powerful! Variable heat settings made it so much easier compared to the previous battery I had. Also way cheaper than other batteries I looked at.

    • O2VAPE

      Thank you Aleesha and welcome to the family!

  29. JanetB (verified owner)

    I’m in love with this little Nano! It’s the perfect inconspicuous vape and goes with me everywhere.

    • O2VAPE

      Awesome! Thanks Janet!

  30. Shay S. (verified owner)

    💕 Wow! Paired with the all glass cartridge, this is by far the slickest and smoothest little gadget I’ve ever had the pleasure of experiencing.

    • O2VAPE

      Thank you Shay~

  31. Marcus (verified owner)

    Love the Nano. Will never go back to traditional battery. Small, discreet, but plenty of battery life. Most of your cartridge will site beside the battery after you screw it in, so the total length of the device + cartridge isn’t much longer than the cartridge itself. The only problem is the device is so small, and I’ve lost it a few times. I plan on buying a couple more for spares!

    • O2VAPE

      Marcus! Thanks so much pick up a lanyard on your next order so you wont loose it LOL 🙂

  32. Marcus (verified owner)

    Bought my second Nano because I liked the first one so much. Nothing wrong with the first one, just wanted to always have a spare.

  33. Elías I.

    Best costumer service I had a problem with my vape and they send me a new one can’t wait to experience the new pen

    Love the feel. Compact as a half lighter, easy to hold and use with arthritic hands. Perfect with vapes from curaleaf in Bellmawr, NJ., Will show it to you if you are in line with me.

    • O2VAPE

      Thanks Annie 🙂

  35. jymbo (verified owner)

    Love it, finally a vape that looks like a zippo,

  36. Kevin S. (verified owner)

    I have 3 O2 vape units (flip, pen, & nano) and the nano is my new favorite…by far. It is SO small and inconspicuous making it easy to keep on me at any time. The variable voltage is a great feature and one I’m impressed to see on such a small device. The battery life has exceeded my expectations as well. My only gripe is a very small one… it has an automatic turn-off feature which I’m sure helps prolong battery life, but I would prefer not to have to click it 5 times to get it to turn back on so often. The only other feedback for future consideration is to have the cartridge less visible. It would be great if you could drop the cartridge into an opening and only have a small visible portion at the bottom to see how much oil remains. Overall though, great product and I would highly recommend!

    • Dana E. Shoched

      Thanks Kevin, We do not have a drop down option at this time that you mention. With those you need a magnetic connector and we have found those not a good fit at this time! Vape on !

    This is a great little monster of a device. So glade I made the purchase. Small nondescript tool I can leave on my desk. I will be buying another one.

  38. Jeff R (verified owner)

    This Nano is a home run with me! Compact and powerful. I love it, glad I spent the money it’s worth every penny! It holds larger cartridges which is why I bought it and I’m very glad I did. This thing is awesome! Great product!!!

    • O2VAPE

      Thanks Jeff, Enjoy!

  39. Nino (verified owner)

    I absolutely love the Nano! It’s perfect and discreet if need be. Also my first battery I had was awkward and to long . So this really is amazing and it fits in my pocket or my clutch and isn’t bulky at all! Thank you so such and amazing product!

    • O2VAPE

      Thank you Nino!! Enjoy and vape on!

  40. Jesse A. (verified owner)

    Great products!! But y’all better do something about your shipping costs!! How do you NOT have free shipping??

    • Dana E. Shoched

      Hi Jesse, Thanks for the review and glad you love the product ! We do offer free shipping you just did not hit the threshold on your purchase 🙂

    This is the perfect battery for me. So small, yet with great features. Just one question…. is there any indication when the battery charge is running low? Thanks!

    • Dana E. Shoched (verified owner)

      Hi Sharon, Thaks so much ..not on this unit but we do have the Patented FLIP ULTRA that has a battery meter 🙂

  43. Jamey F. (verified owner)

    This is a great product. It’s small but powerful. I’ve had it for over a week and it’s still holding a good charge.

    Love Nano. Simple and reliable. Just works!

    • Dana E. Shoched

      Thanks Mitch 🙂

  45. Alex (verified owner)

    Just received it a few hours ago but I already love it! The form factor is awesome, but I could see it being easy to misplace. The lowest setting is perfect with the variable flow cartridges. Overall a nice, discrete little setup. Very happy I purchased it before the ban!!

    • Dana E. Shoched (verified owner)

      Thanks Alex we do sell lanyards if you are worried about loosing it 🙂

  46. Shawn (verified owner)

    Liked it so much a bought a 2nd one. It is small and rips pretty damn good. I also got the O2 all glass carts to use with it after trying the cheap Chinese knockoffs. Save yourself the headaches and go O2 all the way.

    • Dana E. Shoched (verified owner)

      Thanks Shawn! ENJOY…

    High quality construction, long battery life, tiny size… what’s not to love?

    So far the best I’ve used, the cartridges don’t leak, the battery stays charged for hours. Definitely recommend this product and company.👍

    • Dana E. Shoched (verified owner)

      Thanks Ryan 🙂

  49. dana h.

    Really compact and outstanding build quality – my only issue is the settings. Even the lowest is quite a hit. As long as you’re not looking for a low voltage battery, I’d highly recommend it.

    • Dana E. Shoched (verified owner)

      Thanks Dana!

  50. Jane G. (verified owner)

    What a great vape! Nice and small, but packs a punch. Battery is long lasting too which is an unexpected surprise for such a small device. Highly recommend!

  51. jim (verified owner)

    Excellent little vape!

    will be back for more of those carts, too!

    • Dana E. Shoched (verified owner)

      Thanks Jim ! Enjoy!

  52. Jeff P. (verified owner)

    I’ve tried just about every vape battery out there and the Nano is by far the best. It has enough current, 650 mah, to allow big hits, stays charged for over a full gram cart, has variable voltage for the right flavor, very very discreet and it doesn’t use a magnetic adapter. The cart screws right on to the battery. High quality construction. Definitely worth the investment for serious vaping!!!

    • Dana E. Shoched (verified owner)

      Thank you Jeff! Enjoy!

  53. Frank W. (verified owner)

    Its not just tiny, ITS NANO! Works like you expect it to. Very solid little unit. More discrete than the flip Ultra. 1/2 the size of a key fob and works great. 2 Pencil chargers, 2 Ultras and now the Nano. You guys have quality products and excellent customer service. Thanks

    • Dana E. Shoched (verified owner)

      You are most welcome and thanks so much !

  54. Chris (verified owner)

    I got two gift cards and purchased 3-nanos which is the best cart hitting doesn’t look like anything classic O2 vape product on the market today. I also bought 2-lil bittys my other 650 mah batt that works on the carts you have in the drawer like their new and full. To make this hallmark movie story complete I already had 1 nano and 1 lil bitty hence I have a batt for every day of the week. Absolutely phenomenal customer support as well, Hello Seth.

  56. Phineas (verified owner)

    Unit arrived yesterday. So far it’s lived up to the hype. I was disappointed to find the lanyard (which is offered as an accessory option for this unit) does not have a way to readily attach to this model. I blame myself for not reviewing the lanyard before choosing the accessory option during purchase. I have rigged it to work by using the rubber bit and putting it around the body just below the button. This works for taller/skinnier cartridges I get from the store but won’t work for the squatter 1g ceramic cartridge that came with this unit. Looking forward to seeing the longevity of this product.

    • Dana E. Shoched (verified owner)

      Thanks for the review the lanyard you got goes around the cartridge 🙂 Not over the whole body of the pen

  57. Russell (verified owner)

    Form factor is svelte, cartridge stores upright, the hits are clean, and the battery holds well. It’s the best battery I’ve ever owned and bought 2x since I lose them so often. Will definitely support o2vape moving forward, they really earn your business in a saturated market of crappy products.

    • Dana E. Shoched (verified owner)

      Thank you Russell and welcome to the family 🙂

  58. Eric (verified owner)

    Very compact, discreet, stores in upright position, and more powerful battery than similar models. Definitely my go-to vape for on-the-go action. Gotta represent with that o2vape label

      Thanks Eric! Welcome to the family!

  59. Nate (verified owner)

    This little guy is amazing. So discreet and so powerful. The battery lasted for almost a week on a single charge. Perfect for my 0.5g carts. Huge fan.

  60. TripG (verified owner)

    I don’t usually write reviews, but… FAR F’in OUT!
    I bought the Nano vape battery and have been exceptionally please.
    It’s my go to battery. It fits in the front pocket comfortably. Gives some protection to the cart. The battery has a long hang time between charges.
    My only gripe is the color selection. As Henry Ford said about the Model T “ The customer can have any color they want as long as it’s black”.

    • Dana E. Shoched (verified owner)

      Hi Trip, Thanks for the review and hat made me laugh! Sorry only black for 🙂

  61. Johnny G. (verified owner)

    This little thing rocks. I’ve had it through the better part of 2 years and have run it through its paces.. I work this thing hard. I’ve dropped it, got it wet, kept it in hot cars and suitcases.. it’s never wavered. The button is starting to wear, so I’m getting another for the next few years. Good $40 investment here.

    • Dana E. Shoched (verified owner)

      Thank you Johnny G! You do have a lifetime warranty please contact us 🙂

  67. Keri O. (verified owner)

    I have been using mine for about a year, and just ordered another one because it hits better than the rest of my batteries combined! No matter what cart I put in there, it hits nice and smooth. Simple to charge, turn on/off, and is so very tiny and cute. Hides perfectly in your hand. I LOVE IT!!!

    This little thing packs a punch. I love how small and stealthy it is. I can keep this in my pocket without worry of it breaking as well.

  79. Steve O (verified owner)

    Hands down the best vape pen ever, I bought another as a backup. I have three year old carts that have been tried on a dozen or more batteries with no luck. I plugged one in and first hit was like it was a brand new cart. Tried on the rest of my collection of “dead” carts, same experience! If it doesn’t work on this thing, I just doesn’t work. Battery life is at least twice as long as the others I’ve bought. Wish I would have found this sooner.

      WOW ! Thanks and welcome to the family 🙂

    I accidentally left it in my swimsuit when i jumped in the pool. I was in for 20 minutes before i realized what I’d done. The Nano recovered fully within an hour or so.

    • Dana E. Shoched (verified owner)

      Wow ! you got lucky however, if it would have not recovered you have a warranty 🙂

  81. marie (verified owner)

    Powerful little device, smaller than expected (which is great, I was looking for subtle!). It’s shorter than the ccell palm pro for reference, but squatter. The full ceramic and Vari flow Cartridges are really nice, great quality. Not having to use the magnetic connectors is freeing, one less thing to worry about.

    The one thing I’d change, as a personal preference, is to have the chassis be made of some kind of metal, like zinc-alloy or something. I’m just not fond of plastic and would pay a premium for a different material, and it’s difficult to find small devices that are not made of plastic. However, I know some folks prefer how lightweight plastic can be. But that’s the only small niggle I have. I’ll definitely be back for more products!
