Hand crank generator, also known as hand crank DC generator, is a device that produces electrical energy by manually cranking the generator rotor. The basic principle is the phenomenon of electromagnetic induction, in which an electric current is generated by motion. Hand-cranked generators are usually used in emergencies or to provide limited power in remote areas where there is no power source. Although these generators are less efficient and require human assistance, they are small, portable and have flexible usage scenarios for outdoor emergency use.
