Patent ID: 7679320

Claim:
An amusement battery charger comprising: a simulative housing having a simulative feature that provides amusement during grip manipulation; a battery receptacle within said housing adapted to removably receive a battery having a battery dimension; a manual grip on said housing generating kinetic energy; a dynamo within said housing and in mechanical communication with said grip and generating electrical energy from the kinetic energy, said dynamo operative to produce an electrical output; an electronic circuit in electrical communication with said dynamo and said battery receptacle, said electronic circuit generating a conditioned electrical output from the electrical output and transmitting the conditioned electrical output to said battery receptacle; and a power takeoff for transferring a portion of the kinetic energy or the electrical energy to the simulative feature adapted to provide user amusement during grip manipulation wherein said simulative feature is a tachometer on said housing and in electrical communication with said electronic circuit, said tachometer operative to produce a revolutions per minute value in response to receiving said conditioned electrical output from said electronic circuit that is indicative of revolutions per minute of said dynamo during kinetic energy input.
