The Chinese have learned to charge smartphones over the air


Chinese electronics manufacturer Xiaomi has unveiled the world's first "true" wireless charger. The device called Mi Air Charge is capable of charging gadgets from a distance, without direct contact with the base station.


Recall that earlier wireless charging meant a device with magnetic coils inside and a special platform on which it was necessary to put the gadget to replenish its battery. Now, thanks to Mi Air Charge, you can literally charge your smartphone over the air without stopping to use it.

The essence of the work of the Chinese know-how is that the first set of 5 phase antennas determines the location of the gadget in the room, and the other, including 144 antennas, transmits a millimeter-wave signal to it. The latter is converted into electricity directly in the smartphone battery through a special rectifier. At the same time, two antenna units will also be placed in the device for communication with the base station and receiving a signal.


The manufacturer claims that in this way it will be possible to charge several gadgets at the same time with a maximum power of 5 watts. Naturally, such a method of replenishing energy is not available for previously released devices. The company promises that Xiaomi Mi 11 will be the first to receive compatibility with Mi Air Charge. In the future, another one will be equipped with "rectifier receivers" technique Chinese manufacturer.

As for the cost of the wireless charging station, it is promised to be announced in the near future.

    A useful device, for sure the demand for it will be huge. And probably for lead panties too .... among the conservative part of the population with suspicion of such novelties.

    Microwave "vice versa". Did they do the chicken egg test? (For lovers acute I recommend sensations: put a raw egg in the microwave, and turn on for 3 minutes. Remember the word "acute", so I am not responsible for the consequences.) Although it is possible that in China this is how they decided to deal with excessive population growth. good

      There has been no excessive population growth in China for a long time. There, the party is literally extorting for the people to multiply.

      A microwave oven needs a special approach .. If you know how to melt metal, you can melt it. And the egg ... you just need to pierce the yolk. hi

    Science in the PRC has advanced greatly. I guess wireless charging of smartphones is a flower. This technology can revolutionize not only the economy of the whole world, but also fundamentally change the life of people.
    Only an inexhaustible source of energy is required. Copper has just published an article about obtaining energy from solar radiation of the invisible spectrum, which penetrates the Earth with an intensity of 60 billion neutrino particles per second, and the Neutrino Energy Group announced the creation of a material and technology for converting it into electric current.
    One complements the other, so no wires will go, entangling the entire planet will not be needed.

    On copper just came out an article about getting energy from solar radiation

    This system will not work in principle. Because the word "the other day" is spelled together. drinks

      To be honest, I do not quite understand what is the meaning of the shown device. Everyone has sockets at home and at work, and even at railway stations and on trains. Why keep such a canoe?
