Problems solved by technology
[0002] With the rapid development of mobile smart terminals, there are more and more mobile power-consuming devices, and this kind of power-consuming devices are affected by the battery capacity, which brings inconvenience to continuous use. There is a lack of compatibility with various power-consuming devices in the market. Wireless chargers, while wired charging will be affected by the inconvenience of taking power and the length of the charging line, which makes this charging method have some defects, so various wireless charging devices have received extensive attention
[0003] At present, the charging devices on the market are mainly wired charging devices, and some wireless charging devices are also being promoted. However, due to the limitations of different equipment models, many wireless charging devices cannot be used for multiple purposes and need to correspond to specific products. Therefore, the usage is limited. extremely restrictive
