A:Answer If you have the correct cord end (Apple, Android, USB, ETC) to plug into your device and the USB required for the charger, then it will charge your device.
This is basically no different then any automotive 12V battery charger that you would use to charge the battery in your car.
Plug in the charger, connect to your battery (aka device), then sit back and wait (or take a nap and recharge yourself at the same time) !
