You can charge your phone as quickly as if it were plugged into a wall outlet and the charger itself recharges quickly. Some travelers mentioned that on one occasion two of their devices were low and they had them in the car charger. The PowerJack was charged way before the phone attached to the car charger was.

In other instances, they noted that the PowerJak 13000 mAh Dual USB accidentally turned on in their purse and they couldn’t figure out turn it back off. They waited for it to turn off on its own.
