Using a large power generator, smartphones can be charged at 5W in … the air.
Xiaomi today announced a brand new charging technology called Mi Air Charge. As described by Xiaomi, this technology will allow “remote charging” of supported smartphones, even multiple devices can be charged at the same time and can both charge and use., Which is currently not very applicable to the wireless technology.
Xiaomi also outlined how Mi Air Charge technology could work in a blog post. As a result, this technology will require a large power generator, which can be half the size of a normal office. This power generator will charge supported devices at 5W in … air.
“The Xiaomi charger has built-in 5 phase noise antennas that allow you to precisely locate the smartphone from a distance around it. A phase pilot consists of 144 residential antennas. The long wavelength will charge the smartphone directly without contact. ”
This charging technology is completely different from the current Qi wireless charging standard. The smartphone must be equipped with antennas that transmit and receive the signal to convert the received wave signal into electrical energy via a rectifier circuit.
At the current stage, Mi Air Charge technology can simultaneously charge many different devices at a capacity of 5W with a distance of “several meters”. Xiaomi says that obstacles in space don’t reduce charging performance, but there will always be caveats when using this technology.
Previously, OPPO also launched similar technology in April of last year, using a “sphere” to charge directly onto the wavelengths of the OPPO Reno Ace Infinity phone. This technology was originally named by OPPO as FreeVOOC Air, but there is currently no other information about this technology.
With Mi Air Charge, we still don’t know when the technology will officially release. It could be technology with practical products, maybe just a concept to display technology like the MIX Alpha.
