Electronic device

An electronic device includes a power controller and a power motor. The power controller is used to electrically connect a power storage device. The power motor includes a magnetic part and a coil part. The coil part has a main coil and a electromagnetic inducting coil that are electrically connected to the power controller. The main coil is used to drive a relative rotation of the magnetic part and the coil part. The electromagnetic inducting coil generates electricity which is inducted by a magnetic field of the magnetic part. The power storage device is charged by the electricity via the power controller.
