A power adapter includes a housing, an electronic assembly and a protective assembly. The housing has a receiving cavity, and the housing is provided with at least one heat dissipation hole penetrating to the receiving cavity. The electronic assembly comprises a plurality of electronic elements located in the receiving cavity. The protective assembly comprises a connection portion connected to an outer wall of the housing and extending outward, and a protective portion connected to an extension end of the connection portion, the protective portion is spaced apart from the housing. The projection of the protective portion toward the housing covers the heat dissipation hole. The protective portion of the power adapter may shield the heat dissipation hole to prevent external dust from falling into the receiving cavity through the heat dissipation hole. Heat dissipated by the electronic assembly may be dissipated out through the heat dissipation hole.

A wireless charging device includes a plug module, a rack and a wireless charger. The plug module has a top wall, and two opposite side walls connected with two opposite sides of the top wall. A front end of a top surface of the top wall of the plug module is defined as an inclined plane. The rack is mounted on the inclined plane of the plug module. A front end of a bottom surface of the rack is recessed inward to form a lower accommodating groove. The inclined plane is mounted in the lower accommodating groove. A top surface of the rack is recessed downward to form an upper accommodating groove. The wireless charger is mounted in the upper accommodating groove.
