The Vari-Vape variable voltage vape pen battery allows you to dial in exactly the right amount of power for your ultimate vaping pleasure.  Whether you are looking to get a smooth easy pull off of a traditional polycarbonate cartridge or if you are using a ceramic vape cartridge and looking for enough power for a big cloud, and the cleanest hit available on the market, this vape pen battery can do it.


Think this pen is like the others?  Ask them for a lifetime warranty.  We stand behind the quality because we don’t mess around like other brands.  We test and test until we know we have the right components and a long lasting life.  Then we back it up with a lifetime warranty that will allow you to stick with the O2VAPE family.  We want satisfied customers, and this is our way of making sure that you buy with confidence.


It comes with the specially designed usb charger for this battery with every order as well.  While the pen uses a 510 thread, this charger is specially made to charge a stronger lithium ion battery and has a design that will work specifically with this battery. When charging the usb light will be red and green when charged. Please click the button 5 times to turn on and off and hold the button down to get that perfect puff!

*To reduce damage to the battery, Do not use a rapid charger usb or charger that is not made for this product.

    I’ve been using o2vape products for the last 3 years, and this one certainly doesn’t disappoint! I love the fact that it allows you to change the voltage, and it’s extremely sleek and discreet. Will be a lifelong customer.

    Bought two of these. Black and the Silver version. Been using them both for a few weeks and they work great. The variable temperatures seem to be working as intended and it helps that they’re really sleek looking batteries. I like the unconventional “dial” to change the temperature and was uneasy about changing the temperature this way but haven’t had an issue so far! Their customer service is also great. Called them when I thought USPS had messed up my order by giving wrong tracking info but my package got to me the next day. Hate USPS’ unreliability but love the batteries so far 🙂

    Awesome product. Definitely a quality piece that delivers great results. Only bought one to see how I like it, but will definitely be purchasing more. Well worth the extra few dollars you’ll spend versus one of the cheap knockoffs

    I have been frustrated with other pens, lack of battery life per charge, uneven heating etc. Bought the O2 vape pen and have been very happy with it. The adjustable voltage seems to give you a bigger jumping off point if you like. Very happy so far, have tossed all my other pens. This is a winner at a reasonable price.

    I have had mine for three days now and love it. I like bumping up the temp sometimes so that’s very handy. Thanks, DH

    Works great. Best one I’ve used yet and I don’t usually write reviews. Long battery life is a huge plus.
