Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord. It adopts the latest wireless charging technology and transmits electric energy by using the alternating magnetic field generated between the coils. Inductive coupling technology will become the bridge connecting the charging base station and the device. Energy transfer is realized by energy coupling through the coil.
It is to convert electricity through the coil into electromagnetic, and then receive it with the coil and convert it into electrical energy
