The Hohm Run XL 21700 vape battery by Hohm Tech is a high capacity power source intended for vape kits and vape devices. Featuring a larger 4000mAh capacity it can be used for longer before needing to be recharged. The 30A continuous discharge rate means it works very well for sub ohm vaping.

We recommend you always check compatibility with your device before using this battery, the same goes for recharging with an external charger.
