What is a Hand Crank Generator?
A hand crank generator is a portable device that uses human power to rotate a mechanical structure and generate electrical energy. Its principle is based on electromagnetic induction, directly converting kinetic energy into electrical energy. With advancements in materials and manufacturing processes, modern hand-crank generators can now provide stable DC output in a compact size. For example, the multi-functional hand-crank generator launched on the Powerhome website not only achieves breakthroughs in power and efficiency but also meets users' needs for rapid access to electricity in emergency situations.
