About This Product
A hand-crank dynamo shows how motion can be turned into electrical energy. Turning the handle drives a small generator that charges the battery, and the stored energy can then power a light, a radio or a siren. In class, devices like this are used to discuss energy conversion from movement to electricity to light and sound, portable power sources, and the idea of recharging a battery without a mains supply. The USB option gives an alternative route for charging. Alongside supply within India, the 4 In 1 Dynamo Radio And Torch is offered for export to Burkina Faso, Gabon, Botswana, Mozambique and Ecuador.
