Our “Mi Air Charge Technology,” now work over Several distances, says Xiaomi


A few years ago wireless charging seems to be impossible,  but looking forward so many companies have perfected the use of wireless charging on smartphone devices.  your wireless earbuds can also be charged wirelessly.  some  Smartphones like the Samsung S10 series even have the capacity to wirelessly charge other devices.  Xiaomi has taken this to the next level as they have just announced that their “Mi Air Charge Technology,”  can now charge smartphones wirelessly over several meters.

They claim that this wireless charging technology can charge “within a radius of several meters.” and even charge multiple devices at 5W while other physical objects in the range of the charging distance will not interfere with the charge efficiency. Like all of the companies that come up with their marketing strategy, we will have to test it in real life to see if all these are true.

Here is the exact words on how the technology works by Xiaomi:

“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”.
