Do we need Mi Air Charge? Is it harmful to our body?

Xiaomi has announced its remote wireless charging system, Mi Air Charge Technology. They claim it is able to charge devices within a radius of several meters. And multiple devices can be charged at 5W simultaneously, even when there are physical obstacles. What’s more, it will charge your smartphone while you are using it and walking around.


This is “true wireless charge”. It is what we can see in science fiction film in the past. Xiaomi’s president Lei Jun said this technology will be firstly implemented on Mi 11 which will be launched on 28th December 2021.

Do we really need Mi Air Charge Technology?

The wireless charger on the market adopts electromagnetic induction technology. This is a mature technology. High charging efficiency is one of its advantages. The conversion rate is usually around 80%. However, its disadvantages are also obvious. The devices must touch the charging board, and the free charging distance is almost zero.

Mi Air Charge Technology is a kind of radio frequency technology. The principle of it is to use the space electric field as the medium of energy transmission, which will bring a significant breakthrough in the charging distance. With it, the charging mode become more flexible.


Of course, the problem of Mi Air Charge Technology is also obvious. The charging efficiency is relatively slow. Although, the 5W charging speed is too slow comparing to other charging methods on the market, most of the similar solutions introduced by pioneering companies only have a charging speed of about 1 to 2 watts.

In the near future, Xiaomi’s self-developed remote charging technology can also charge smart watches, bracelets and other wearable devices in space. It can realize wireless power supply for the living room, speakers, desk lamps and other small smart home products. We will completely get rid of the shackles of wires, and get a real intelligent living room.

Is it harmful to our body?

You may doubt that whether Mi Air Charge will do harm to people. We didn’t find any explanation about the electromagnetic radiation on the promotion page of Mi Air Charge Technology. All countries have strict control over the radiation exposure value of electronic product. Therefore, if Mi 11 comes with Air Charge Technology, we can believe it meet the safety standards.
