China's Xiaomi is constantly striving to innovate and bring new, hitherto unknown technologies not only for the world of smartphones. This is exactly what the revolutionary Mi Air Charge technology is, which is wireless charging spread through the air. Welcome to the 21st century!
Mi Air Charge Technology: Forget about cables
Thanks to a revolution in current wireless charging methods, Mi Air Charge technology enables users to remotely charge electronic devices without any cables or wireless charging stands. With the new technology from Xiaomi, we are entering a real era of wireless charging.

Charging via Mi Air Charge Technology works with a special charging station developed by Xiaomi himself. The station uses beam shaping technology to send millimeter waves directly to the device. These waves are converted into electrical energy, which charges the device.
How does it work ?
The beams are transmitted using 5 built-in phase interference antennas, which can accurately detect the position of the smartphone. The technology also includes a phase control field composed of 144 antennas, which transmits the mentioned millimeter waves.
However, the smartphone itself must also be ready for this technology. Xiaomi has developed miniaturized antennas for smartphones, similar to those found in the station itself, only smaller.
The "beacon antenna" transmits position information with low power consumption. The receiving antenna system consisting of 14 antennas converts the millimeter wave signal transmitted by the charging stack into electrical energy through the rectifier circuit. It is this part that turns charging air into science fiction into reality.
Charging performance is limited
At present, the technology is able to achieve charging with a power of 5 W within a few meters. The advantage is the possibility of simultaneous charging, etc. multiple devices at once and not even physical obstacles do not reduce the efficiency of charging.
We also have a presentation video that shows how the technology works:

Although charging performance is not outrageous at the moment, we believe that Xiaomi will continue to develop the technology and we will see a real wireless time in the future. The mere fact that Xiaomi managed to make the air charging really work is really fascinating.
In the future, smart watches and smart home devices
Xiaomi wants to take this technology even further. According to Adam Zeng Xuezhong, the new head of Xiaomi's mobile division, it is planned that Mi Air Charge Technology will charge wearable devices such as smart watches and fitness bracelets in the future.
The technology is also expected to be able to power other small household appliances, such as speakers or table lamps. The manufacturer's goal is to eliminate the need for cables, which have become a threat in most households.
