An electrical adapter is supported by a housing and includes an electrical plug assembly having an input for receiving a high voltage, a converter electrically coupled to the assembly for converting the high voltage to a low 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 low voltage to the electrical device, and is enabled to retract the cable. In a preferred embodiment, the retractable cable assembly includes slots defined within a bore of a cable reel to support a pair of first interengageable electrical contacts coupled to the other end of the low voltage cable. These electrical contacts rotationally mate with a pair of second interengageable electrical contacts disposed along the axis of rotation within the retractable cable assembly. One of the first contacts includes a pair of edges defining a gap therein. One of the second contacts defines a sleeve having a spiral inclined portion. When the contact having the gap rotates around the sleeve, the problem of intermittent electrical contact that arises with the gap rotating about the sleeve and coinciding with gaps within the sleeve is eliminated, and continuous electrical contact is established therebetween.
