Abstract
An electrical adapter having a manually retractable cable assembly where the electrical contacts of the retractable cable assembly are disposed along an axis of rotation to minimize the friction between the cable and contacts therein when the cable is extended and retracted. The electrical adapter includes a housing; an electrical plug assembly including an interchangeable module coupled to an adapter module, the interchangeable module having a plurality of prongs for receiving a first voltage when mated with an electrical receptacle, and a converter electrically coupled to the assembly for converting the first voltage into a second voltage; and a retractable cable assembly supported by the housing and electrically coupled to the converter. The retractable cable assembly includes a cable coupled at one end to an electrical plug for outputting the second voltage, a reel for winding and unwinding said cable, the reel being rotatably supported by the housing, a wheel mounted to the reel for enabling the cable to be manually dispensed from and retracted into the housing.
