Extract Tank Battery Kit

Introducing our 510-thread rechargeable battery, bundled with a versatile USB charging adapter for multiple applications. The inhale draw-activated battery offers user-friendly operation and portability. Simply connect the USB charging adapter to the battery and insert it into a compatible port. The illuminated tip remains lit during charging and flashes 20 times before automatically switching off when fully charged. A charged battery is indicated by the absence of light on a plugged-in device. After charging, detach the USB adapter and connect your Extract Tank. The buttonless pen activates effortlessly when you inhale.
