Features 1、This hand crank electricity generator could help kids to understand generation of electricity, quite suitable for adult and children to play together Specification Description: The hand-cranked generator provides up to 6V for experiments requiring a power supply. The clear plastic housing is lightweight and durable. These jumper cables provide a connection to an electrical circuit. It includes a LED lamp and can be used as a flashlight. It also comes with one resistor. Teachers in elementary and secondary classrooms could use this generator as an education kits to demonstrate through hands-on activities. Parent could give this kit to kids as a great gift. Features: This hand crank electricity generator could help kids to understand generation of electricity, quite suitable for adult and children to play together. Slowly rotate the crank one circle each second and the voltage could reach 3V that could easily lighten a LED. This set comes with one pair of jumper cables with alligator clips at each end for quick and convenient connection. Connect the generator to the resistor and the LED light, it would be a beautiful and small emergency light. The voltage could reach 6V at most from a quite fast rotation, so rotate the crank faster might burn the LED.
