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.

Claims

1. A portable electronic device holster, comprising:

a holster housing for carrying a portable electronic device by a user and for holding the portable electronic device while the portable electronic device is being charged; and

an AC voltage convertor captured within said holster housing, said AC voltage convertor comprising;

a convertor housing;

at least two AC prongs for connecting to a standard AC power socket extending from said convertor housing;

a voltage down convertor circuit mounted within said convertor housing for generating a down converted voltage from a standard AC voltage coupled from the standard AC power socket by the at least two AC prongs; and

at least two low voltage contacts coupled to said voltage down convertor circuit for coupling the down converted voltage to battery charging contacts on the portable electronic device, wherein

said battery charging contacts and said at least two low voltage contacts are connected when the portable electronic device is inserted into said holster housing, and wherein

said AC voltage convertor can be extended for charging the portable electronic device and can be retracted otherwise.

2. The portable electronic device holster according to claim 1, wherein the at least two low voltage contacts are doubly insulated from the at least two AC prongs.

3. The portable electronic device holster according to claim 1, wherein said holster housing is designed to hold a selective call radio.

4. The portable electronic device holster according to claim 1, wherein said holster housing comprises an attachment clip.

5. The portable electronic device holster according to claim 1, wherein said voltage down convertor circuit is a transformerless integrated circuit.
