Through the above structure and in combination with the magnetic assembly, the reliability of the electrical connection between the power adapter 10 and the mobile power supply 20 or the wireless charging connector 30 can be realized.

[0048] In one embodiment of the utility model, the above-mentioned mobile power supply 20 further includes a fourth DC port 26 electrically connected with the second circuit board 22, and the fourth DC port 26 is located on the end face of the second shell 21 other than the second DC port 24 (that is, the fourth DC port 26 and the second DC port 24 are located on different end faces of the second shell 21 respectively). Correspondingly, the wireless charging connector 30 includes a fifth DC port 36 electrically connected with the third circuit board 32, and the fifth DC port 36 is located on the end face of the third shell 31 where the third DC port 34 is located (that is, the fifth DC port 36 and the third DC port 34 are located on the same end face of the third shell 31), and the fifth DC port 36 is matched with the fourth DC port 26 and is electrically connected with the fourth DC port 26 in a plug-in manner. Through the above structure, the mobile power supply 20 and the wireless charging connector 30 can be used in combination, the power stored in the charging battery of the mobile power supply 20 is used to supply power to the wireless discharging module 33 of the wireless charging connector 30 (that is, the voltage conversion circuit of the second circuit board 22 can convert the power stored in the charging battery and output to the wireless discharging module 33 through the fourth DC port 26 and the fifth DC port 36), and then the mobile device is charged. Of course, the mobile power supply 20 can also be connected to the power adapter 10, and the wireless charging connector 30 is connected to the mobile power supply 20 at the same time, as shown in Figure 1 , so that the mobile power supply 20 and the mobile device placed in the wireless charging module 33 are charged at the same time through the power adapter 10.

The above structure can improve the stability and reliability of the connection between the fourth DC port 26 and the fifth DC port 36, and at the same time improve the surface consistency of the wireless charging connector 30 (that is, avoid the surface from protruding when carrying).

[0051] In an embodiment of the present application, the first shell 11, the second shell 21 and the third shell 31 are all cuboids, and the cross sections of the first shell 11, the second shell 21 and the third shell 31 perpendicular to the preset direction are the same; the first DC port 14 is located on the end face of the first shell 11 perpendicular to the preset direction, the second DC port 24 and the fourth DC port 26 are respectively located on two end faces of the second shell 21 perpendicular to the preset direction, and the third DC port 34 and the wireless discharge module 33 are respectively located on two end faces of the third shell 31 perpendicular to the preset direction.

This structure is conducive to inserting the entire mobile device wireless charging device into the AC socket (for example, wall plug) on the vertical surface.

[0053] In particular, in the power adapter 10, the end face of the first shell 11 on which the AC connector 13 is located includes a third recess (for example, two third recesses corresponding to two pins in the AC connector 13 can be included), the AC connector 13 is arranged in the third recess through a second pin shaft, and the AC connector 13 protrudes from the surface of the first shell 11 by rotating around the second pin shaft, thereby being inserted into the AC socket through the part protruding from the surface of the first shell 11.
