Hand Crank Powered Devices -

Build your own electric vehicles and machines then power them up with a hand-crank generator that makes and stores electricity.

Experiment with your electric generator and your models: Alter the crank-time and the crank-frequency and see how these variables affect the performance of your cars and machines.  Compete with  your friends to see whose car runs fastest and farthest!  The hand crank generator doubles as an LED flashlight.

The hand crank dynamo contains a rechargeable lithium (LIR2032 or LIR2032H) 3.6v battery which should be replaced after approximately 500 charging cycles or if a reduction in the charging capacity of the dynamo is observed.  Contains an electroluminescent diode class 1

Use only LIR2032 or LIR2032H Lithium Battery

DO NOT USE non rechargeable mercury batteries (CR2032)
