Patent attributes
A nickel metal hydride/nickel cadmium secondary battery charger includes: a charging base having a lower casing and a cover; a charge control circuit board installed in a containing space of the lower casing; a power supply plug with its external end corresponding to the cylindrical shape of a cigarette lighter in a car for connecting a power supply and conducing electric power, and its internal end being a protruding ear and having a protruding axle pivotally coupled to both sides of the protruding ear, and a conducting wire passed through the interior of one of the protruding axles and connected to a power supply input terminal of the charge control circuit board. The power supply plug uses two protruding axles of the protruding ear as an axis to be rotated and folded from 0° to 180°, so that the protruding axles is extended in front of the charging base or folded in the opposite direction into the battery compartment to facilitate its carrying and reduce its storage space.
