1 Theoretically, wireless charging technology is not harmful to human body. The principle of resonance of wireless charging is that magnetic field resonance can only be transmitted between coils of the same frequency resonance, while other devices cannot accept the band. In addition, the magnetic field used by wireless charging technology is harmless to human body. But wireless charging is a new technology, and many people worry that it will be as innocuous as wi-fi or phone mast.
2 Wireless charging technology USES magnetic resonance to transmit electrical energy in the electric and magnetic fields between the charger and the device, while coils and capacitors generate resonance between the charger and the device.
3 The system could be widely used in the future, such as charging zones for electric cars and power transmission for computer chips. The charging system developed using this technology requires only 1/150 of the current charging time
4 Conversion rates have long been a concern, with wireless charging losing less than wired charging. Wireless charging has a few percentage points higher conversion rate than wired. High conversion is also the key factor for wireless chargers to be applied globally. However, wireless charging technology is also limited by distance. In the future development, it is necessary to solve the problem of accurate positioning of wave band and magnetic field range for long-distance transmission.

5 The core chip is one of the difficulties in the application of wireless charging technology. Precision radiation range control, magnetic field frequency, and other controls are implemented by the chip.
