This is a more advanced pen vape battery than the pen vape batteries with the on/off button.
All Automatic!! No button to turn off to save battery for next use!!
No more.. Argh!! I forgot to turn it off again. It’s Dead
Universal 510 threading so this heavy duty battery pen will work with all standard carts.
Members report that 1 full charge lasts over 2 carts and sometimes 3 carts before needing to recharge it.
