[ 20. A charger plug capable of connecting with a two or three receptacle power source to convert l20V input power received from the power source to DC output power, the charger plug being electricallv connectable to a rechargeable electronic device via a power cord for providing the DC output power thereto, the charger plug including a housing, the charger plug comprising:
first and second separate blade members non-movably secured within the housing so as to have prong portions of the blade members positioned in order to extend in a first direction from a front wall of the housing, the prong portions adapted to be received in the receptacle openings of the power source;
the charger plug including a DC connector having an aperture adapted to removablv receive a corresponding power cord plug end for transmitting DC power to the rechargeable electronic device;
the charger plug housing forming a) a charger plug face area defined by the front wall b) an outer profile defined by a perimeter of the front wall and defined by a plug body extending rearward from the front wall and c) a rear end opposite the front wall;
a printed circuit board located within the housing and haying the DC connector mounted thereon, wherein a rearward extent of the blade members ends before a front edge of the printed circuit board and the housing has a connector opening at the rear end for proyiding access to the DC connector aperture by the power cord plug;
the charger plug configured to be capable of plugging into a standard wall outlet and further:
i) being sized so that the charger plug housing comprises a longitudinal length extending between the front wall and the rear end and the longitudinal length is less than 2.0 inches and
ii) the outer profile haying no interference with an adiacent receptacle of the power source located on all sides of the first receptacle when a like charger plug is mounted in all ayailable orientations in any of the other receptacles,
so that when space is limited by an obstacle adiacent or in front of the power source the charger plug is capable of being conveniently mounted to one of the receptacles, the power cord plug end may be conveniently received by the DC connector and the power cord plug end can be conveniently removed from the DC connector while leaving the charger plug connected to the receptacle.]
