The related art is only described in other patent documents or academic papers.

The wireless charging stand 10 has a body 12 including a top surface 121, a bottom surface 122, and side surfaces 123 connecting the top surface 121 and the bottom surface 122. The side surface 123 may be vertical or inclined from the bottom surface 122 toward the center of the top surface 121. The surface of the body 12 is formed into a column or a vertex. In this embodiment, the side surface 123 is a square cylinder surrounded by four planes, and the bottom surface 122 serves as a base of the body 12. Each side surface 123 is provided with a charging plane area 124, and the charging plane area 124 is set to The flat surface ensures maximum performance during the wireless charging process.
