It’s definitely enough to last you a day or two of vaping – and it’s pretty easy to just swap out your current cartridge for the USB charger when you run out of juice. The O2 Vari-Vape has a 600mAh battery, which is on the high side for battery capacities in 510 pens. The 6 possible voltage levels (between 3.3 V to 4.8V) are laser printed onto the main device body, while the dial has textured grooves for better grip. The O2 Vari-Vape sidesteps this issue by having a twist dial located at the base. Most other devices utilize the firing button for cycling through and selecting the current-voltage – which means having to press the same button repeatedly, contributing to wear and tear. The base of the device is where it really differs from the pack of 510 pens out there.

The LED lights up as you press and draw, and will blink once the device is running low on power. The unit I tested for this review has a shiny gunmetal finish, with a single firing button- encircled by an LED ring. The O2 Vari-Vape has a pretty standard design, like most pen style devices – it’s definitely portable, sleek, and fits into any pocket or purse. The slim kit ceramic version of the device comes with an empty cartridge and a metal carrying case while the premium version comes with the same inclusions, but with the cart already pre-filled for you. Although, there are a few kit options offered by O2. Much like most 510 batteries, the O2 Vari-Vape comes with a pretty lean kit consisting only of the device itself and the matched USB charger.

They were even one of the first manufacturers of draw-activated vape pens – which is now a very popular feature across several devices. Since 2013, they have been providing decent quality vaping products like 510-threaded batteries, wax pens, and dry herb vapes such as the Dryonic II ( review). O2Vape is a veteran-owned company that’s based in Michigan.
