The customized 15W wireless magnetic power bank refers to devices and devices with built-in batteries that obtain power through wireless induction for charging. Wireless charging technology is derived from wireless power transmission technology. Its working principle uses the principle of induction cooker. When the current passes through the coil, a magnetic field will be generated; and the generated magnetic field will form a voltage, and after the voltage, a current will be generated. With current, it can be charged, and now this technology has been used in customized 15W wireless magnetic power bank.
The principle of customized 15W Wireless Magnetic Power Bank: it is the conversion of magnetic energy into electrical energy, which is based on the principle of induction cooker.

Because wireless charging requires a transmitter and a receiver, the customized 15W wireless magnetic power bank is equipped with a transmitter on the basis of conventional mobile power, and the charging mobile phone supports wireless charging and has a wireless charging receiving coil. In the case that there is a coil at the sending end and the receiving end, the coil at the sending end is connected to a wired power supply to generate an electromagnetic signal, and the coil at the receiving end induces the electromagnetic signal at the sending end to generate a current to charge the battery.
Advantages and disadvantages of customized 15W wireless magnetic power bank:
The interactive data is convenient, the transmission speed is fast, the operation is simple, and the multi-function is integrated. The disadvantage is that the charging can only be performed at a short distance.
