The sleek design of the AVD Alpha Pen Battery features a removable cap that covers your 510 thread cartridge, keeping it concealed and discreet. No more broken carts - the metal cap provides protection from drops and falls.
AVD’s PowerWave™ technology helps stabilize temperatures and regulate the heat generated by the cartridge. With haptic vibration, you’ll know the battery is activating without needing to look for LED light indicators.
