ABSTRACT:
A jump starter has a hand-held charger case (1) that contains an internal battery (8), a battery charger (7), connections and controls that provide a needed variety of foolproof and convenient care of external batteries (9) such as vehicle batteries. Control components and circuits are provided to prevent overcharging and incorrect connection to batteries and to allow an external battery to be charged directly by the charger or by the internal battery. Cables, connections and controls allow the charger to accept AC electricity through an AC input cord (3) or DC electricity through a DC input cord (4) and respective converters (5, 6). Jump-start cables (27, 28, 29) with clamp connections (30) are positioned on opposite sides (34, 37) of the charger case and supportable by covered nonconductive cleat-support members (30, 31) to prevent contact with each other or with other objects when not in use. The AC input cords and DC input cords are positioned on opposite sides of the case for additional safety.
