PORTABLE POWER STORAGE DEVICE WITH A SELF-GENERATION AND NANO-CAPACITOR STORAGE STRUCTURE

The present invention provides a portable power storage device, and in particular, a portable power storage device with a self-generation and nano-capacitor storage structure. The portable power storage device includes: opposite fixed magnet plates disposed on both sides of a main body and having a plurality of radially arranged induction magnet bodies; and a rotating coil plate disposed between the opposite fixed magnet plates and having a plurality of radially arranged coil bodies to perform mutual induction action with the induction magnet bodies, such that when the rotating coil plate is rotated or reciprocated, electric charges are induced in the coil bodies by the induction magnet bodies to generate current, thereby electricity may be easily generated and used at all times regardless of the location, as well as the stored electricity may be output and used in a portable electric device as necessary.
