Watch magnetic charging principle is the use of electromagnetic wave induction principle for charging, the principle is similar to a transformer. There is a coil in the sending end and the receiving end. The sending end coil is connected to the wired power supply to generate an electromagnetic signal, and the receiving end coil senses the electromagnetic signal at the sending end to generate an induction current.
The main circuit of the magnetic wireless charger is composed of two parts, which are the wire head unit circuit and the coil transmitting unit circuit. Whether it is the wire part or the emission part, the entire charging position is fine, the size is very small, and the aluminum profile back shell is full of science and technology.
