The battery charger (2) recharges the battery (1) when the electrical cord (7) is in use. The battery (1) supplies 12 volts of low voltage electricity to the DC/AC converter (3). The DC/AC converter (3) converts the 12-voltage electricity to a higher powered 115 volts electricity, which supplies the motor (6). The motor (6) turns a gear-driven generator (4), which supplies voltage to the battery charger (2) and recharges the battery (1). To help keep a longer charge in the battery (1), the power is controlled by a toggle switch (9) and relay (8), which disconnects the power supply.
