Charge your phone across the room! Mi Air Charge!

As tech enthusiasts, we were quite excited when the first wireless charging pad was introduced. But it was not futuristic enough. The tech was based on age-old concepts and at times, it was more inconvenient than simply using a charging cable. We kept waiting for “real” wireless charging to be invented for consumer use, and turns out, that day might not be too far!

Last friday, Xiaomi introduced Mi Air Charge technology. They claim that this “remote charging technology” can charge multiple devices at once, “while walking around or even when something’s in the way”.

“Xiaomi’s self-developed isolated charging pile has five phase interference antennas built in, which can accurately detect the location of the smartphone. A phase control array composed of 144 antennas transmits millimeter-wide waves directly to the phone through beamforming.”

To put it simply, think of the tiny chargers that uses 144 antennas in the base station sending millimeter-wide waves to your phone, which receives them on a 14-antenna setup of its own.

“Soon our living room devices, including speakers, desk lamps, and other small smart home products, will all be built upon a wireless power supply design, completely free of wires, making our living rooms truly wireless.”

Imagine walking into a café in the near future and getting your phone charged, while its being used! As wonderful as this technology may seem, it has a long way to go to prove its feasibility and safety. In the meantime, let’s keep our fingers crossed!
