Xiaomi has just announced the Mi Air Charge technology. The remote charging technology is said to charge multiple devices simultaneously and top up your smartphone while using it and walking around or even when something’s in the way.
The transmitter looks pretty big, around the same size as a side-table next to a sofa. What it does though is that it is said to provide a 5W charge wirelessly to a smartphone.
The wireless charger is totally different from the Qi standard and because of this, smartphones will need to have a “miniaturized antenna array with built-in ‘beacon antenna’ and ‘receiving antenna array’.” The smartphone has 14 antennas to convert a millimeter-wave signal that’s emitted by the charging device. The signal is then converted to electric energy through a rectifier circuit.
Xiaomi claims that the new technology can charge multiple devices with a 5W current within a radius of “several” meters. The company teases that the Mi Air Charge tech would eventually be compatible with smartwatches, fitness bands, and other wearables.
Currently, there’s no release date announced for the Mi Air Charge system and it’s unknown if it will be available in the consumer market as well.
It might be a while before we see this fully fleshed out but it is refreshing to see new innovations in wireless charging technology.
