Wireless charging mobile power, as the name suggests, you can charge your phone without a data cable! Here's how it works: electricity generates magnetism and magnetism generates electricity. After the power switch is turned on, the electromagnetic circuit converts the electric energy of the power supply battery into a large amount of magnetic energy, and then uses a reverse coil (the international standard brick QI coil) to receive this large amount of magnetic energy, converts it into electrical energy, and passes through a metal output head to our equipment reserve battery.
Because electromagnetic transmission only needs to be transmitted in space, no medium is required, so wireless charging can be carried out. This is the formation of wireless mobile power. It's a power bank.
