Does the wireless charging device cause any harm to the body?

With the development of wireless networks, the era of everything connected is getting closer to us. The development of the Internet of Things has also driven the development of wireless charging technology. Wireless charging technology, with its outstanding convenience, is being increasingly applied in mobile devices. Some people are worried that the electromagnetic radiation from wireless charging will affect human health. However, this concern is completely unnecessary.

During the process of power transmission by the wireless charging coil, the specially designed wireless charging coil generates a directional magnetic field, converting the electrical energy into magnetic energy and transmitting it to the charging device. The charging device receives the magnetic energy through the wireless charging coil and reversely converts the magnetic field into electrical energy, storing it in the battery. To reduce energy loss during the transmission process, magnetic shielding plates are added in the wireless charging coil to prevent the unnecessary spread of magnetic fields. The transmission efficiency of the wireless charging system is over 80%. The remaining 20% of the energy is dissipated as heat through the wireless charging coil during the energy conversion process. The wireless charging coil can adjust the charging power according to the device's requirements. When the device does not need charging, the wireless charging coil's magnetic field is automatically turned off to avoid unnecessary energy loss.
