The mainboard chamber 210, the plug-in board chamber 220, the inverter chamber 230 and the battery cell slots 240 are respectively provided with a mainboard 300, a plug-in board 400, an inverter 500 and a battery cell 600. The mainboard 300 is electrically connected to the input end of the plug-in board 400 and the inverter 500, and the battery cell 600. The plug-in board 400 is electrically connected to the DC output port 110 and the charging port 130, and the AC output port 120 is electrically connected to the output end of the inverter 500.

[0026] The battery cell 600 is charged through the charging port 130, and the electric energy released by the battery cell 600 is supplied to electronic products using direct current from the DC output port 110, and the electric energy released by the battery cell 600 is supplied to electronic products using alternating current from the AC output port 120, and the functions are relatively complete; because the mainboard chamber 210, the plug-in board chamber 220, the inverter chamber 230 and the plurality of battery cell slots 240 are separated, the mainboard 300, the plug-in board 400, the inverter 500 and the battery cell 600 are also separated, so that the mutual influence of the components can be avoided, especially the influence of the heat generated by the inverter 500 on the battery cell 600 is avoided; and due to the setting of the bracket 200, the structure of the entire portable mobile power supply is relatively compact, the volume is small, it is easy to carry, the structural strength is relatively large, and the components of the portable mobile power supply are not easily damaged when vibrating or colliding, and the reliability and safety are good.

The cell slot 240, the main board chamber 210, the plug-in board chamber 220 and the inverter chamber 230 are compactly and reasonably distributed with good safety. The main board 300, the plug-in board 400, the inverter 500 and the cell 600 do not affect each other, which is conducive to the heat dissipation of the inverter 500 and the cell 600, and the heat transfer between them is very small, so as to avoid the heat of the inverter 500 affecting the work of the cell 600. And because the cell slot 240 is arranged on the peripheral side of the bracket 200, it is convenient to disassemble and assemble the cell 600.

[0028] In some embodiments of the present invention, a cooling fan 231 is provided on the side wall of the inverter chamber 230, and a ventilation window 140 is provided in the housing 100 in the area corresponding to the cooling fan 231. The cooling fan 231 and the ventilation window 140 are conducive to the flow of air in the inverter chamber 230, thereby accelerating the speed of heat dissipation of the inverter 500. The ventilation window 140 is also conducive to the heat dissipation of other components inside the housing 100, avoiding the internal temperature of the portable mobile power supply to be too high, thereby avoiding the reduction of the working efficiency of the portable mobile power supply, reducing the hidden dangers of fire and explosion of the portable mobile power supply, and having good safety performance.
