Features Educational and Entertaining: This hand crank electricity generator is a perfect tool for kids to learn about electricity generation and can be enjoyed by both adults and children for interactive learning experiences. Quick Voltage Generation: By rotating the crank at a speed of one circle per second, the generator can produce a voltage of 3V, easily lighting up an LED for various applications. Convenient Connection: Equipped with a pair of jumper cables featuring alligator clips, this set allows for quick and hassle-free connections to other devices. Compact Emergency Light: When connected to a resistor and an LED light, this generator creates a beautiful and small emergency light, providing practical illumination in emergency situations. Powerful Output: With fast rotation, the voltage output can reach up to 6V, but caution is advised as excessive speed may cause the LED to burn out. Features: 1、This hand crank electricity generator could help kids to understand generation of electricity, quite suitable for adult and children to play together 2、Slowly rotate the crank one circle each second and the voltage could reach 3V that could easily lighten a LED 3、This set comes with one pair of jumper cables with alligator clips at each end for quick and convenient connection 4、Connect the generator to the resistor and the LED light, it would be a beautiful and small emergency light 5、The voltage could reach 6V at most from a quite fast rotation, so rotate the crank faster might burn the LED Specification: Description: The hand-cranked generator provides up to 6V for experiments requiring a power supply. The clear plastic housing is lightweight and . 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.
