Abstract: This is directed to a power adapter plug arm manufactured from a single piece of material. The plug arm can include a plug operative to extend into a wall socket, an elongated plate coupled to an end of the plug such that the plug extends from a first surface of one end of the plate, and a pin coupled to the opposite end of the plate and extending from the opposite surface of the plate.
