Abstract: The present utility model discloses a kinetic energy power bank, comprising a housing, a power generation device, a circuit board, and an energy storage battery. The circuit board is connected to the power generation device. The power generation device has a magnet and a conductive coil disposed therein. In the present utility model, the design of an energy conversion circuit and a layout structure inside the housing is optimized. In this way, the structure of the circuit becomes simpler, costs and electric energy loss are reduced, and the energy conversion rate is higher. Besides, the problem that normal operation of the device is affected due to element interference with each other and thermal energy accumulation is resolved.
