Car Charger Plug. Works with most usb wire chargers, check the recommended input voltage for your charger to ensure it is compatible.

This Charger has 2 amp output that is strong enough to run a pass-through or charge most cell phones.

This product will not charge an e-cig on its own, it is merely an adapter that plugs into your car's charge port/cigarette lighter and has a USB outlet.  It requires a separate USB wire charger to charge a battery.
