Abstract: The disclosure provides a portable charging device with kinetic energy recovery comprising a machine body, a kinetic energy recovery component, an AC-DC electric energy conversion component, and an energy storage component. The kinetic energy recovery component is embedded in the machine body by a locking assembly, and comprises a ring body, two springs, a conductor coil, a permanent magnet sphere, a guide rod, two sealing covers, and two bumps. The two sealing covers are symmetrically and fixedly attached to both sides of the ring body, and the middle part of the ring body and the two sealing covers form a vacuum cavity. The energy storage component is arranged at the right side of the machine body. The AC-DC electric energy conversion component is arranged at the bottom side of the machine body, and two first conductive blocks are electrically connected to the AC-DC electric energy conversion component.
