Most of the current mobile wireless charger, such as iPod and iPhone, are charged through the direct contact of metal wires. The advantage of wireless charging technology lies in its convenience and versatility. The disadvantage is that the efficiency is low and the power can only be provided. At the same time, the audio and video files can be synchronized to the device through the USB interface. However, mobile phone wireless charging technology will bring progress to WiFi and battery technology. For devices that do not require data transmission, this new technology will greatly reduce the number of chargers required by users. In addition, through the use of wireless charging technology, the public mobile device charging station will become a reality.
