Hand-held, manually-operated battery charger with emergency light
First Claim
1. A hand-held, manually-operated battery charger comprising:
- a generator that creates a voltage at an output;
a handle operably connected to the generator, wherein the generator creates the voltage in response to turning of the handle regardless of whether the handle is turned clockwise or counterclockwise;
a full-wave bridge rectifier connected to the output of the generator, wherein the bridge rectifier allows the handle to be turned either clockwise or counterclockwise to create the voltage, and converts the voltage to a DC voltage;
a supercapacitor that stores the DC voltage;
a connection port that receives a connection cord that provides the DC voltage from the supercapacitor to a battery-charging port of a battery-operated device;
a superbright light-emitting diode (LED) that receives the DC voltage from the supercapacitor; and
a switch that switches the DC voltage between the connection port and the LED based upon whether the connection cord is attached to the connection port, wherein the DC voltage is diverted to the connection port when the connection cord is attached to the connection port, and wherein the DC voltage is diverted to the LED when the connection cord is not attached to the connection port.

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.
