Xiaomi released self-developed 5W air-to-air charging technology (Mi Air Charge Technology): it can be charged even when covered by foreign objects, Xiaomi 11 takes the lead.
News from Gadget Pixels, 29 January Xiaomi today launched its self-developed air charging technology and announced a poster. This technology does not require a base, and long-range wireless charging can be achieved whether in hand or in the pocket. Xiaomi 11 mobile phone is the first to implement this technology. Prior to the release of Xiaomi, Motorola today also publicized its wireless charging technology and released a demonstration video.
As seen in the video, unlike Motorola’s technology, Xiaomi’s air charging technology is not affected by foreign objects. The official said that the phone does not need to be kept in a fixed position, and it can be charged wirelessly from a long distance when playing in the hand or in a trouser pocket.
Gadget Pixels was told that Lei Jun today introduced air charging technology in detail on his personal public account, and demonstrated the air charging pile at the same time. Currently, Xiaomi’s air-to-air charging technology has achieved 5-watt long-range charging over a range of several meters for a single meter. Not only that, but many devices can also be charged at the same time. (Each device supports 5 watts), and even blocking foreign objects does not reduce charging efficiency.

He said that this technology holds 17 technical patents, and the core technology lies in the state of space and energy transmission. The self-developed aerial charging pile has built-in 5 phase interference antennas. Those who can place the mobile phone in the millisecond space and accurately locate the position of the mobile phone. The phase control array composed of 144 antennas transmits millimeter waves to mobile phones through beamforming.
In favor of mobile phones, Xiaomi has developed its own antenna array. Among them, the “beacon antenna” transmits position information to the space field through low power consumption. A “receiving antenna array” composed of 14 antennas realizes science fiction separation of the millimeter wave signal emitted by a charging pile into electrical energy through a rectangular circuit. Empty Charge Experience.
Lei Jun also said that Xiaomi’s self-developed air-to-air charging technology can also charge wearable devices such as smart watches and bracelets. In the future, living room, speakers, desk lamps and other small smart home products can realize wireless power supply. Can completely get rid of the strings of wires, and really realize wireless living room.
Following is the official introduction of Xiaomi’s (Mi Air Charge Technology):
Just think, what is the charging method in the future? Maybe once you enter the house. So you do not need any charging cable or charging base. It does not matter that you keep the phone in your pocket. Or hold it, you can automatically charge in the air.
Today, we bring scenes like this that exist only in reality in science fiction films. Xiaomi officially released its own developed space charging technology, the first to enter the era of true wireless. Self-developed air charging system 17 technical patents.
Xiaomi’s main technology in space charging is spatial positioning and space energy transmission. The self-developed aerial charging pile has built-in 5 phase interference antennas. Which can detect mobile phone in millisecond space and can accurately locate mobile phone location. The phase control array composed of 144 antennas transmits millimeter waves to mobile phones through beamforming.
On the mobile phone side, Xiaomi has also self-developed the miniature design of the antenna array. Containing “beacon antenna” and “receive antenna array”. The beacon antenna transmits location information to the space field through low power consumption. An antenna antenna array composed of 14 antennas converts the millimeter wave signal emitted from the charge stack into electrical energy through a refinement circuit. Which makes a sci-fi isolated charging experience a reality. Currently, Xiaomi’s Mi air-to-air charge technology has achieved a radius of several meters.

Not only this, simultaneous charging (each device supports 5 watts) without reducing charging efficiency, many devices can also be blocked by foreign objects.
The living rooms of the future will enter a completely wireless era. In the near future, Xiaomi’s self-developed space charging technology can also charge smart watches, bracelets and other wearable devices in space. In the future, living room, speakers, desk lamps and other small smart home products can realize wireless power supply. Can completely get rid of the strings of wires, and really realize wireless living room.
It is a revolutionary innovation in wireless charging. It is also a bold attempt to make the entire house wireless. This is not science fiction. Is rather technology. This is Xiaomi’s self-developed space charging technology.
