The housing 1 serves as the main frame of the charger, with a sealed upper end and an open lower end. The light-transmitting cover 5 has an open upper end and a sealed lower end, with its upper end snapped into contact with the lower end of the housing 1.

[0034] like Figures 2-4 As shown, the first wireless charging unit 2 includes a bottom shell 21, a top cover 22, a first wireless charging coil 23, and a first magnet 24. The bottom shell 21 is dampedly hinged to the upper end of the housing 1, and the bottom shell 21 and the top cover 22 are snapped together to form a closed cavity, in which the first wireless charging coil 23 and the first magnet 24 are placed. A charging placement plate is provided on the top cover 22, and the first wireless charging coil 23 and the first magnet 24 are mounted on the bottom shell 21 and close to the charging placement plate, wherein the first magnet 24 is annular and sleeved on the outside of the first wireless charging coil 23. Through the above arrangement, the first wireless charging unit 2 has two position states: one is a first position state in which it is placed on the top of the housing 1 and its charging placement plate is in a horizontal position; the other is a second position state in which the first wireless charging unit 2 is rotated by a certain angle so that its charging placement plate is in an inclined position. The bottom shell 21 is dampedly hinged to the upper end of the housing 1, so the first wireless charging unit 2 can be stably maintained in the inclined position. Because the first wireless charging unit 2 is equipped with a first magnet 24, even in the second position, the electronic device to be charged can be magnetically attached to the charging placement plate for charging. This allows the user to use the electronic device while it is being charged, such as watching videos or using their phone. Furthermore, at this time, the second wireless charging unit 3 is exposed, allowing it to be used to charge other electronic devices.

[0035] like Figure 3 , Figure 5 and Figure 6As shown, the second wireless charging unit 3 includes a fixing plate 31 and a second wireless charging coil 32. Both the fixing plate 31 and the second wireless charging coil 32 are installed inside the housing 1. The second wireless charging coil 32 is parallel to and close to the top wall of the housing 1, which serves as the charging placement area for the second wireless charging unit 3. A charging area marking is provided on the top wall of the housing 1 directly opposite the second wireless charging coil 32; for example, if the second wireless charging unit 3 is defined as an earphone charging unit, its charging area marking would be an earphone icon.
