The 5000 mAh 21700 battery is a high-capacity spare cell for vaporizers that use the 21700 format. A charged spare in your pocket means a dying battery never ends a session; carrying a second cell effectively doubles your time away from a charger.

Swapping takes seconds on vaporizers with a user-replaceable cell, and when the original battery finally wears down, a fresh 21700 restores full runtime, so the device outlives its battery.

Intended for use with: Arizer Go SRT, DynaVap HyperDyn, DynaVap M7, DynaVap UniDyn, Frolic Vaporizer, Tempest 2 and YLL Induction Heater 3.0.
