1, increase the output, can be selected from the equipment, select a good electromagnetic coil. Because the transmitter and receiver of wireless charging are covered with wireless charging coils, the coils will have losses when working, and the use of good materials can reduce the coil loss, which can greatly improve the efficiency of wireless charging.

2, reduce the loss, you can optimize the line and component selection to deal with. Streamline and optimize the line, and select good materials for components to reduce output losses.
