To enter a true wireless charging era, Global technology leader Xiaomi today has introduced a brand new form of charging called Mi Air Charge Technology.
According to the company, the new Mi Air Charge is designed to let users remotely charge their electronic devices including smartphones without any cables, pads, or wireless charging stands.
The company gives a brief note of how the technology works in a blog post. 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 a 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, the new Mi Air charging technology is capable of 5-watt remote charging for a single device within a radius of several meters.
Xiaomi teases that its Mi Air Charge tech would be eventually compatible with smartwatches, fitness bands, and other wearables. However, the company has not yet to revealed the release date and offer for the Mi Air Charge system.
