[0006] Preferably, a rotating plate rotatably connected to the back of the housing is provided, and the mounting plate is fixedly connected to the rotating plate and rotates therewith.

[0007] Preferably, a plurality of rectangular heat dissipation holes are provided on the side of the housing, and the heat dissipation holes are communicated with the accommodating groove.

[0008] Preferably, the accommodating groove extends along the length direction of the housing, the power module is arranged inside the accommodating groove, and a gap is provided between the power module and the groove wall of the accommodating groove to form a heat dissipation duct.

[0009] Preferably, the cooling fans are spaced apart and arranged in an upper and lower arrangement, and the air outlets of the cooling fans face the power module.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] Since at least two power modules are provided inside the housing, and each power module is provided with multiple different types of wiring ports, it can meet the usage requirements of a variety of electronic devices with different interfaces, thereby improving the wide adaptability of the mobile power supply to different electronic devices. In addition, a heat dissipation module for dissipating heat from the power modules is provided on the back of the housing. The provision of a cooling fan can greatly improve the heat dissipation efficiency of the power modules, thereby increasing the service life of the mobile power supply.
