The wireless charger charges the mobile phone through the principle of electromagnetic induction. A coil on the charging pad converts magnetic energy into electricity, which charges the phone's battery. Wireless chargers are usually made of glass, because glass has a better guiding effect on the magnetic field, which helps to improve the charging efficiency. Wuhan Jianghan Road anEquipped with 60 street lights with wireless charging function, each street lamp has two charging positions to support high-power charging.
The principle of wireless charger charging is that there is a coil in the mobile phone device, which can convert the magnetic energy at the charging board into electrical energy, and then it can be constantly charged from the circuit board. This is also why the wireless charger is made of glass, because glass has more advantages in magnetic induction and faster charging.
