    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.

    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!

    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!!!

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

      Thank you Kari!

    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 !!

    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!

    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!

    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!!
