ABSTRACT:
A hand-held, manually-operated battery charger is disclosed having a generator that creates a voltage when a handle is turned by a user. A bridge rectifier is connected to the output of the generator and converts the voltage to a DC voltage, regardless of whether the handle is turned clockwise or counterclockwise. A supercapacitor stores the DC voltage. The charger also includes a connection port that is adapted to receive a connection cord. The connection cord receives the voltage from the supercapacitor and provides the voltage to a battery-charging port of a battery-operated device. The charger also includes a superbright LED that also receives the voltage from the supercapacitor. Voltage is switched between the connection port and the LED, such that the voltage is diverted to the connection port when the connection cord is attached thereto and is diverted to the LED when the connection cord is not attached.
