This is a true pass-through battery.
The KGO or EGO USB Pass-Through with 1000mAh rechargeable battery allows you to vape on the go as well as giving you full power while connected to your USB port. You can use it while it is charging on any USB port, via the included USB cable. It cannot be charged with the standard EGO and KGO charger. If you don't have a computer to plug the charging cable into you will need to purchase a Wall Plug Adapter or a Car Charger to plug it into.
