The application of wireless charging technology in consumer-grade electronic products

The principle of wireless inductive power transmission is to transfer electromagnetic fields through the transmitting coil and receiving coil in a short distance, and to transmit electrical energy through the magnetic field. Currently, the radio power transmission technology cannot independently and stably supply power to devices. The device end still needs to rely on batteries to store electrical energy, so it is usually called wireless charging technology. This technology is highly favored by users in the field of portable devices due to its unparalleled portability.

Wireless induction charging is widely used in consumer electronic devices such as laptops, mobile phones, headphones/AirPods, and watches. Currently, almost all portable devices need to consider adding wireless charging ports to provide convenience for users. Wireless charging technology does not require wire transmission, breaking through the limitations of physical interfaces. Compared with wired charging technology, wireless transmission technology can minimize the specific requirements of different devices for chargers to the greatest extent. Wireless charging technology provides a friendly interface, reducing electronic waste by improving its universality.

The current drawback of wireless charging is that its structure is more complex than that of wired charging, resulting in an increase in cost. Wireless charging requires additional wireless charging coils at both the charging end and the device end. Moreover, it is less efficient than wired chargers and generates more heat. These drawbacks have limited its application in mid-range and low-end devices that aim for cost-effectiveness. However, as this technology continues to develop and be promoted, it is believed that these problems will have excellent solutions in no time.
