We have used many types of charges like wired charge, USB charger, and wireless charging, fast wireless charging arrived, And a lot more. And here we are talking about Air Charging which does not have any cable to charge the device nor any wireless pad so that you can keep your mobile or devices to charge.
Recently Xiaomi has released their concept video of air charging stating that your phone will start charging automatically wherever you entered the room.
Xiaomi says the new Mi Air Charging technology will deliver 5W of power to any device remotely, covering a distance of up to two meters from the “self-developed isolated charging pile.” Multiple devices can be charged simultaneously using this tech, according to Xiaomi.

How Xiaomi Mi Air Charge works:—
The Mi Air Charging technology’s pile has 5 phase interface antennas that accurately determine the position of the mobile phone. The phase control array of the pile — composed of 144 antennas — will directionally transmit millimeter-wide waves through beamforming.
The receiving device, e.g. a smartphone, must have a miniaturized antenna array with a built-in “beacon antenna” and “receiving antenna array” in order to charge the battery wirelessly.
The former tells the pile the smartphone’s position, while the latter is a 14 antenna array that converts the millimetre-wave signal into electrical energy through the rectifier circuit.
“Xiaomi’s patented Mi Air Charging Technology makes use of a special self-developed tower/box-like device that uses beamforming technology to send millimetre waves directly to a device. These waves are converted to electric power that charges the device.” – Xiaomi
There are also health concerns, and there’s no doubt that if this technology ever makes it to market, it’ll be heavily scrutinized by regulatory authorities.
“This new wireless charging technology can charge devices at a speed of 5W, even in the presence of physical obstacles that don’t reduce charging efficiency.
It comes with a phase control array composes of 144 antennas, which emits millimetre waves through beam-forming, creating electric energy via a rectifier circuit.” – Xiaomi
What are the issues and concerns related to Air Charging?
Health issue:–
Xiaomi’s Air charging technology utilizes electromagnetic radiations in the transparent medium unless it’s converted to electrical signals at the transmitter and the receiver circuits.
The overall radiation may become strong enough to start interfering with the physiological functioning of human and animal cells.
