Extract Labs 510-thread battery
The rechargeable kit comes with a USB cord for multiple uses. The draw-activated battery is simple to use and easy to carry. Attach the USB cord to the battery and plug it into a suitable port. The light tip stays lit while the battery is charging. When fully charged, the tip will flash 20 times and then turn off. If a plugged-in device is not illuminated, the battery is charged. Remove the USB adapter and attach an Extract Tank. The buttonless pen activates upon inhalation.
