Xiaomi Mi Air Charge wireless charging technology just gets better

Xiaomi Mi Air Charge wireless charging which enables you to charge your capable devices anywhere in your room.

Xiaomi today just ventured a step further into wireless charging technology by introducing the Mi Air Charge. It is a big step into the right direction. Once this technology matures, I’ll safely predict that we’ll see many more devices being manufactured to adopt this method of charging up.

Xiaomi Mi Air Charge features are awesome

Mi Air Charge enables remote charging through the air, so no more cables needed and you don’t have to rest your devices on the wireless charger as well.

The next advantage of remote wireless charging is that you’ll free to roam around and use your smartphones whilst it charges too.

But being able to only charge at 5 watts for the time being, I don’t think that heavy gaming sessions will not drain out the battery but at the very least it will last longer by you being in the vicinity of the Mi Air Charge.

The best feature for me concerning Xiaomi’s remote charging device is that it is able to charge multiple devices at the same time and they claim that physical obstacles does not degrade the charging efficiency. Each wireless charging enabled devices will still be charge at 5 watts.

How does the Xiaomi Mi Air Charge wireless charging work?

Lets use a wireless charging enabled smartphone as an example. Xiaomi has managed to develop a technology where the remote charger can identify the location of the smartphone using the built in five phase interference antennae up to a few meters.

Through beam-forming, the Mi Air Charge transmit millimeter wide waves directly to your smartphone to charge it up using a phase control array composed from 144 antennas.

A miniaturized antenna array with built-in ‘beacon antenna’ and ‘receiving antenna array’ is manufactured into the their smartphones. The beacon antenna acts as a positioning broadcaster relaying location information whilst the receiving antenna, composed from 14 antennas converts the broadcasted millimeter wide wave transmitted by the charging unit into electric energy through the rectifier circuit.

What used to only be in sci-fi movies, is now a reality!

Wireless living rooms and workspace

Technology moves fast. When wireless charging matures, I hope that it will not only be used to charge small devices. Such as smartphones, smartwatches and the likes.

Imagine having your OLED smart television, sound bars, game consoles and controllers, tablets, laptops, refrigerator and many other appliances getting power without needing to be plugged into a wall socket anymore.

I think that should be the goal and whoever manages to get there first would certainly have a golden goose in their hands. Xiaomi has paved the way, it is possible and attainable.

Current wireless charging technology using inductive charging

The current wireless charging pads operates via inductive charging where electromagnetic inductions are used to provide electricity to the devices. You can see the adoption of this technology in flagship smartphones and smartwatches. For example in the new Samsung Galaxy S21 series, OnePlus 8 Pro and Apple’s Watch series.

The most common standard used with the current wireless charging technology is the open interface standard named Qi. If you’re wondering how to pronounce the word, you can say the word ‘Cheese‘ without the ‘se‘. That should be good enough. Try it.

Wireless charging started off with the ability to charge at 5 watts in year 2010. Wireless charging using the electromagnetic pad can negotiate charging as high as 30 watts in 2017.

Conclusion – Xioami’s Mi Air Charge bridging sci-fi into reality

What we used to see in sci-fi movies is now turning into reality. It is far from perfect but strides heading towards that direction is being made.

The remote charging device is not yet for sale. The Chinese tech giant Xiaomi has not yet made any announcements of when it would hit the shelves. Our grubby little fingers just need to wait a little bit longer I guess.

But for now, I’ll be sticking with my 65 watt warp charge for sure.
