ABSTRACT:
A portable electronic device holster (105) includes an AC voltage convertor (115) having at least two AC prongs (102) extending therefrom. The AC voltage convertor (115) is captured within the holster (105) and can be extended and retracted. When a portable electronic device is inserted in the portable electronic device holster (105), the AC voltage convertor (115) is extended, and the at least two AC prongs (120) are inserted into a standard AC power socket, a voltage down convertor circuit (405) within the AC voltage convertor (115) generates a down converted voltage which is coupled to the portable electronic device. Alternatively, an AC voltage convertor (615) slidably attaches to a portable electronic device and generates a down converted voltage which is coupled to the portable electronic device when AC prongs (120) extending from the AC voltage converter (615) are inserted into a standard AC power socket.
