ABSTRACT:
A universal AC adaptor has a transformer unit for converting standard AC line voltage to DC voltage and a plurality of plugs. Each plug has a flexible lead coupled to an output cord from the transformer unit at a coupler box. The leads allow the plugs to move independently of one another. Each plug also has a socket having a particular configuration which is different from the sockets of all the other plugs. Each socket is configured to mate with a particular receiving socket of a DC or an AC electrical appliance. The AC adaptor has enough plugs so as to be useable with most of the models of electrical appliance of a particular consumer electronic market, for example, video game units.
