Wireless charging technology mainly uses electromagnetic technology, which converts current into electromagnetic in the transmitter. The mobile phone converts the electromagnetic current into a current through the built-in chip receiver to charge the mobile phone. The key to the promotion of wireless charging technology lies in ensuring that all manufacturers' wireless chargers are compatible, and the Qi standard has been formulated to make wireless charging have a unified technical specification to ensure the compatibility of the same charger for multiple brands and multiple products. Menno Treffers, chairman of the Wireless Power Alliance, said that the Qi wireless charging standard uses electromagnetic induction technology, which is more efficient and safe than other technologies. The Qi wireless charging standard includes three aspects of interface, performance, and regulation, which will pose considerable challenges for the popularization of wireless charging technology. Therefore, the Qi standard mobile phone will be able to pass any Qi-certified charging base station, base, or other rechargeable battery. The device is wirelessly charged. Qi's first advance requirement for the device is no more than 5 watts, which may be a major limitation for some manufacturers who hope that laptops can also pass wireless charging technology.
