The Bee Buzz’n VV Auto-Draw vape pen battery has touch-tip variable voltage adjustment functionality, very similar to O Pen vape. This Battery is powered by Honeystick technology. You cycle through the power settings by tapping on the stylus touch tip. It comes with a screw-in USB charger. If you’re looking for an auto-draw vape pen that has a little extra power kick with variable voltage, then pick yourself up a B-Buzz’n VV auto-draw vape pen.
