    Great Vape Pen. I have tried Dr. Dabber Ghost and Kandy Pen, and O2Vape is THE BEST I have tried so far! On top of that the O2Vape pen is half of the cost of those other pens. Would DEFINITELY buy it again

    Works great for me at all voltage settings.
    Lasts a long time between charges (3+ carts).
    Very satisfied.

  6. Monique (verified owner)

    Outstanding battery. Charges quickly and it keeps the charge for a very long time. It feels sturdy without being super bulky. I’ll be buying more!

    Just Outstanding Products. Never a issue with settings, works great.. I also would recommend the Flip Ultra.

      Thank you JF, Stay safe!

  9. Jessica G. (verified owner)

    Had the 900mah battery for almost a week now. I’ve been through roughly 15 different brands and O2 vape seems to be the winner. Smart design and great idea with the light blinking a different color than temperatures for the variable voltage feature. Smooth button, clean hits, holds a solid charge, and 900mah! I will definitely recommend and be back.

    • O2VAPE

      Thanks Jessica! VAPE ON!!!

  10. Kari W. (verified owner)

    Excellent products and customer service! The 900 lasts several days between charging! O2 Vape guarantees their products

    • O2VAPE

      Thank you Kari!

  11. Luke S (verified owner)

    This is an excellent battery indeed. Why anyone would give this battery less than 5 stars, considering it has a lifetime warranty, is beyond me. This price is on point and the only “catch” is I have to pay to ship it back if/when it goes bad. Excellent product! Thank you very much!!

    • O2VAPE

      You are most welcome Luke! But THANK YOU !!

  12. Hayden (verified owner)

    This is now my 3rd battery from 02 , ive been using this brand for maybe a year and a half now and ive never had an issue. Ive given one battery away and my other 2 i use one for home and the other for work. They stay charged for a few days and also the connecting end never gets wore out like some of the competitor brands. I will always purchase from 02!

    • O2VAPE

      Thanks Hayden!

  13. Tony (verified owner)

    Works great. Love it. Thanks

      Thanks Tony!

    Once again 02VAPE hits it out of the park. Great product, great customer service. You just have to get used to the USPS being strangled by their bosses. dps

    • O2VAPE

      Thank you David! Remember we do have UPS as an option for delivery you do not have to pick USPS unless you have a PO BOX and we really are not using USPS right now but we do have it as a option still. Thanks again and VAPE ON!

  15. James W. (verified owner)

    This vape pen works great! With 900mah I don’t have to worry about charging it everyday, which is great. I also really like the variable voltage feature.

    • O2VAPE

      Thanks James glad you like it !

  16. Rachel (verified owner)

    The battery life is great! I’ve charged it once since I took it out of the box over a week ago and it gets daily use. It looks and feels nice as well and I get good airflow with my cartridges. And the price point is great compared to some of the other big name batteries!

    • O2VAPE

      Thank you Rachel, VAPE ON!!

  17. Adam (verified owner)

    Very happy with this pen and the variable voltage. It’s easy to use and works great especially with the thicker oils that my other battery struggled with. Because it’s a pen it works with some of the oddball cartridges as well.

  18. Beth B. (verified owner)

    This battery is solid. I bought two to have a spare. Worth every penny.

    • Dana E. Shoched

      Thank you Beth, welcome to the O2 family!

  21. Savannah K (verified owner)

    I’ve had this for 2-3 weeks now. In love with it. I did literally over 5hrs of researching batteries, and chose this in the end. Good price, amazing battery life, great design, great product. Still have yet to charge mine.
    I love the variable voltage as well, it’s super cool!
    I got the grey one, happy I did, I love how it looks, and it’s so smooth.

    • Dana E. Shoched

      Thank you so much Savannah and welcome to the O2 FAMILY!!

  22. Christopher (verified owner)

    I have eight for two years and ordered everything from everyone from one coast of this country to the other and I can definitely say that 02 has the best hardware to utilize product and that I will never use anyone else for batteries or cartridges! Very professional goods and service

    • Dana E. Shoched

      WOW! Thanks so much and welcome to the family !!

  23. Carly R. (verified owner)

    Great battery that lasts for a really long time and provides great heating. Bought this as a backup, but it might become my main battery.

  30. Michael S. (verified owner)

    Excellent product so far so goo

  31. Christina (verified owner)

    Great battery life! Lasted several days (with plenty of life to spare) while backpacking. Thank you!

    • Dana E. Shoched

      Thank you !

  32. Dave M. (verified owner)

    We have other O2Vape products, but the battery life makes this one stand above the others. It is JUST as reliable and consistent as our pens with a lower number of MaH, but this one lasts a ton longer. We’re loading it with Hybrid cartridges, and bring it with us if our “main” vape battery runs out of juice while out. I can’t wait to bring it to National Cannabis Festival in April!

  33. Jose B. (verified owner)

    The 900 mah xl vari vape is the best of them all. It has the strongest heat settings to power and rip my all-glass carts I fill with rosin and diamonds from O2 Vape. This is the best mod battery since its designed and heat settings perfected for their brand of vapes carts.

  34. Andrew (verified owner)

    Lifetime warranty and a fast charge that literally lasts for days. I won’t be bothering with other brands from here on. Customer service is responsive. I got lucky finding O2VAPE, because otherwise I probably would have gone through several more expensive, inferior batteries over the last few years in search of the quality device that is the vari vape 900.

    • Dana E. Shoched

      Thank you Andrew !Welcome to the family!

  35. Jeff (verified owner)

    Excellent battery. It is easy to use and has great build quality. Should last a long time

  36. Scot Boswell (verified owner)

    I’ve bought 2 grey one’s already they would last 2 1oz cartridges now they have died over time this wood grain battery only lasts through part of a 1oz cartridge

  37. Noah (verified owner)

    These are awesome! Can’t believe how much bigger hits they give with the extra capacity! No more struggling to get a cloud. One of the 3 i ordered was acting up and the company has me a new one in 4 days. Lifelong customer
