Xiaomi presented the Mi Air Charge technology on January 29 in the morning. According to the company, "remote charging technology" can charge multiple devices simultaneously and will recharge a smartphone that is being used.

Currently this technology would be capable of offering a remote load up to 5W for a single device in a radius of several meters; although they point out that soon it will also be possible to charge several devices simultaneously under this same power limitation.

Mi Air Charge remote charging is based on spatial positioning and power transmission. Thus, the company has developed an isolated charging battery with integrated five-phase interference antennas, capable of accurately detecting the location of the smartphone. A wave phase control matrix made up of 144 antennas transmits millimeters directly to the phone via beamforming technology.

Smartphones must be equipped with a "set of miniaturized antennas with built-in 'beacon antenna' and 'set of receiving antennas'". The smartphone has 14 antennas to convert a millimeter wave signal that the charging battery emits. The signal is converted into electrical energy through a rectifier circuit.

Xiaomi's new proposal, dubbed Mi Air Charge, promises to charge mobile devices wirelessly without any contact. This new technology is based on spatial positioning to transmit energy to the device. Of course, it should be noted that it is not yet a commercial reality, it is an advanced prototype.
