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.

Abstract: A generator control system capable of realizing series-parallel connection comprises a first generator, a second generator, a first inverter and a second inverter, wherein a power output terminal of the first generator is connected to a power input terminal of the first inverter, and a power output terminal of the second generator is connected to a power input terminal of the second inverter. The generator control system further comprises a series-parallel connection box, and the first inverter and the second inverter are connected to the series-parallel connection box. Various voltages and power can be provided through the change-over switch.
