Abstract

A portable power bank device with a projecting function comprises a battery unit, a control unit, and a micro projector unit. The battery unit is electrically coupled to a charge unit and restores power from an external power source. The control unit is electrically coupled to the charge unit and a connection interface unit, respectively. The control unit comprises a charge module, a voltage conversion module, and a video codec. A battery power source of the battery unit is outputted through the voltage conversion module. The micro projector unit is electrically coupled to the control unit and projects and displays video signals of the video codec.
