Xiaomi MI Air charger?

 

 

Xiaomi has just announced what seems to be the biggest leap in smartphone technology they built a wireless power station, which can charge your phone over the air such that you'd never need to plug it into anything again. It basically figures out where your phone is within a room and then it fires a narrow beam towards it which can be converted by the phone into charge. In 2017 many other companies have tried this and failed. We had the Mother Box that could broadcast up to 10 watts of power in all directions. also, energizer's whose concept was almost identical None of them have worked why well because air charging is hard because the power limit per device is capped at 5 Watts.

The main thing to note is that Xiaomi's own cable charging can deliver 120 watts of power which can charge the phone up to 41 percent in 5 mins. The other major problem is that you need not just the base station but also you need a phone that has a beacon antenna that is active all the time to constantly communicate with the base station to make sure it knows where to fire the beam of charge but also 14 other antennae a just to be able to convert that air charged into actual battery juice. this means that this method of air charging will not work with existing phones.

Another concern the existing problem with the current standard of wireless charging is the fact that it's super inefficient compared to a cable, which is directly connecting the power source via a highly conductive metal but every time you try and charge through wireless charging pads that energy has to pass through not just the metal but almost always a sheet of plastic from the charger and glass on the back of your phone and these are not highly conductive materials and so as a result much less of the energy you put in actually ends up as a charge on your phone and much more of it ends up as heat, which is not just a complete waste of resources, but it's also actively bad for your batteries Health.

Well, air charging is even more wasteful because as well as all of the inefficiencies of normal wireless charging we've now got to use even more energy to not just locate and keep track of where the phone is, but also potentially to fire this beam across 5 meters worth of air and all of this is not even factoring in that the charging station is the size of a fridge the fact that it probably costs as much as your phone.

But Xiaomi is not currently selling this they also know the cons of this method of charging they are just giving hints that they are working on this type of technology. Xiaomi is a company that does like to test experimental technology like their MI mix alpha.

The good thing here is that Xiaomi's charging station can actually charge multiple devices at once call but not just that even more significantly they're saying it doesn't matter if other objects come in the way now this is kind of confusing because this whole air charging thing is based on the same millimeter waves the 5 G's which Has definitely affected with interfering objects so if Xiaomi have actually figured a way to get around this then fair play to them and this whole big problem of the charging power is capped at 5 Watts. if they find a way to overcome this we're not going to need batteries anymore. First, they will start with low-power devices that you only keep in your home like TV remotes, like smart speakers that soon enough it will reach smart bands and even smartphones will start massively shrinking the amount of battery. The battery is the main contributor towards both thickness and weight and batteries are the primary reason that we have to keep swapping our phones every couple of years.

They're the fastest degrading component. This means that our phones will last longer and most battery-related problems will be solved.

So the concept of air charging very possibly be future, but the real turning point will come when a big company announces that they go to a retail-ready version of this. Thank you so much
