Key features of wireless chargers

1. Theoretically, wireless charging technology is safe and harmless to the human body. Wireless charging uses the resonance principle of magnetic field resonance, transmitting power only between coils resonating at the same frequency, while other devices cannot receive the wavelength. Furthermore, the magnetic field used in wireless charging is itself harmless to humans. However, wireless charging is still a relatively new technology. For example, many people worry that wireless charging will cause problems like Wi-Fi and mobile phone antenna rods when they first appeared. In reality, the technology itself is harmless.

2. Wireless charging technology uses magnetic resonance to transmit electrical energy in the electric and magnetic fields between the charger and the device. The coils and capacitors create resonance between the charger and the device.

3. This system has wide applications in the future, such as charging areas for electric vehicles and power transmission for computer chips. Charging systems developed using this technology require only one-one-hundred-and-fiftieth of the current charging time.

4. Conversion rate has always been a concern. Research by MIT shows that wireless charging technology has higher losses than wired charging technology. The wireless charging conversion rate is several percentage points higher than wired charging. High conversion efficiency is also a key factor enabling the global application of wireless chargers. However, wireless charging technology is limited by distance, and future development will inevitably require solving the problem of precise positioning of wavebands and magnetic field ranges for long-distance transmission.

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