This refers to the fact that the power outlet (cigarette lighter) connector for this charger/mount serves a dual purpose. It has a wire coming out of it that goes to the phone mount (to charge your mounted phone wirelessly) and it also has a USB port on it. This allows you to charge another phone in your car (using a USB cable that you provide) at the same time.
