ABSTRACT:
A mobile power tool and appliance operating system includes a portable lead-acid battery pack having a high current capacity socket compatible with existing low current plugs used with appliances intended to operate from automotive cigarette lighter sockets. Matable high current capacity plugs are attached to power tools and appliances through retractable cords. The battery pack is receivable in a 120 VAC powered charging base having a self-contained charging circuit including a transformer and a voltage regulator. The high current socket housing prevents inadvertent operation with an automotive cigarette lighter plug, and the high current plug housing prevents electrical contact in a automotive cigarette lighter socket, for safety reasons. In another embodiment, the battery pack is provided with two sockets for delivering different power outputs at each respective socket. Recharging of the battery pack can also be accomplished via connection made to one of the sockets.
