## Abstract

A portable energy-storage power supply device comprises a shell, a control module, a battery module and an inverter module. The inverter module is installed on a right shell through bolts. A slot for installing a wireless charging cover is formed after a left shell and the right shell are assembled together. A charging coil holder for fixing a wireless charging coil is disposed on an inner side of the wireless charging cover. The portable energy-storage power supply device has the advantages that installation is convenient, operation is easy, the layout of internal parts is reasonable, and the width of the shell is small.
