Abstract
A multi-power charger comprises an internal battery, receptacles for connecting one or more external power sources, and output receptacles for connecting to an electronic device. A voltage selection circuit determines an operating voltage of the first device and selects a power supply source to supply the operating voltage the device. The power supply source may be the internal battery, one of the external power sources, or both. The operating voltage is delivered to the device via the output receptacle.
