A hand-cranked generator is a device that converts mechanical energy into electrical energy using manual effort. By turning a crank, users can generate electricity, which can be used to power small devices or charge batteries. This type of generator is often used in emergency situations or remote locations where traditional power sources are unavailable. These generators typically consist of a rotor, stator, and a crank mechanism. As the crank is turned, the rotor spins within the stator, creating an electric current through electromagnetic induction. Hand-cranked generators are simple, portable, and provide a reliable source of power when needed, making them useful for outdoor activities or during power outages.
