Xiaomi has announced Mi Air Charge Technology enabling remote wireless charging of smartphones and other accessories.
Revolutionizing the current wireless charging methods, Mi Air Charge Technology enables users to remotely charge electronic devices without any cables or wireless charging stands. Today, we enter a true wireless charging era.

Mi Air Charge Technology – 5W remote charging
The core technology of Xiaomi’s remote charging lies in space positioning and energy transmission. Xiaomi’s self-developed isolated charging pile has five phase interference antennas built in, which can accurately detect the location of the smartphone. A phase control array composed of 144 antennas transmits millimeter-wide waves directly to the phone through beamforming.
On the smartphone side, Xiaomi has also developed a miniaturized antenna array with built-in “beacon antenna” and “receiving antenna array”. Beacon antenna broadcasts position information with low power consumption. The receiving antenna array composed of 14 antennas converts the millimeter wave signal emitted by the charging pile into electric energy through the rectifier circuit, to turn the sci-fi charging experience into reality.
Currently, Xiaomi remote charging technology is capable of 5-watt remote charging for a single device within a radius of several meters. Apart from that, multiple devices can also be charged at the same time (each device supports 5 watts), and even physical obstacles do not reduce the charging efficiency.

In the near future, Xiaomi plans to make its technology work with smart watches, bracelets, and other wearables. In envisions a future where speakers, desk lamps, and other smart home products will have a truly wireless power supply design.
