ear charging induction coil

The wireless charging coil for ear charging is a kind of wireless charging coil. Its characteristics of small size, strong stability and fast charging speed are favored by the market. The wireless charging coil for ear charging is a coil designed based on wireless charging technology. Originating from wireless power transmission technology, low-power wireless charging often adopts electromagnetic induction type (such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method adopts inductive type), and high-power wireless charging often adopts resonance type (most Electric vehicle charging adopts this method) The power supply equipment (charger) transmits energy to the electric device, and the device uses the received energy to charge the battery and at the same time for its own operation. Because the charger and the electric device The energy is transmitted between the two by magnetic field, and there is no wire connection between the two, so the charger and the power-using device can be made without exposed conductive contacts.
