ABSTRACT:
A charging accessory for a portable electronic device having a device input connector includes a main charger body portion having a power supply connection to an AC wall outlet that receives an AC power supply voltage. Power conversion circuitry converts the AC power supply voltage to a DC power supply voltage. A device connector is electrically coupled to the DC power supply voltage and configured to couple the DC power supply voltage to the device input connector of the portable electronic device. The main body also has a battery pack connector that is electrically coupled to the DC power supply voltage. The battery pack connector couples to a battery pack through a charging body connector that electrically connects to the battery pack connector and receives the DC power supply voltage when the battery pack is mounted on the main charger body portion. A rechargeable battery in the battery receives the DC power supply voltage to recharge the rechargeable battery. A device connector allows the battery pack to be directly coupled to the device input connector on the portable electronic device to provide an addition portable power supply for the device.
