Exemplarily, the DC jacks 23 are of multiple types.

[0048] The first rotating plug 22 is placed opposite to the first connecting socket 14 along the first direction, and the first rotating plug 22 can be plugged into the first connecting socket 14, so that the orientation of the plurality of DC sockets 23 is opposite to the orientation of the plurality of AC sockets 13 along the first direction. For example, the first rotating plug 22 can also be located in the second housing 21.

The AC module 10 and the DC module 20 are electrically connected to the connecting jacks through a rotating plug, which increases the functions of the desktop power supply 100. The AC module 10 and the DC module 20 are detachably connected, which is convenient for use in different scenarios.

[0051] Exemplarily, the desktop power supply 100 includes a plurality of dual-pin AC sockets 13 and a plurality of triple-pin AC sockets 13 .

[0052] Exemplarily, the first shell 11 is in the shape of a cuboid, the second shell 21 is in the shape of an irregular hexahedron, and one end surface of the second shell 21 along the first direction is an inclined surface.

[0053] Exemplarily, the material of the first shell 11 and the material of the second shell 21 are both high-temperature resistant and flame-retardant plastic materials, which can prevent combustion or other accidents caused by high-temperature fire while providing insulation, thereby improving the safety of the desktop power supply 100.

[0054] Exemplarily, a portion of the power cord 12 is located outside the first housing 11 , and another portion is located inside the first housing 11 , and is connected to the AC socket 13 and the first connection socket 14 through different circuits.
