Haha, they wanna sell me on this - wanna make look cool - all i think is - wow that spot is so dated my devices don’t need charge - they have a lifetime battery.

I mean we have 2020 this small step thinking is so 90s - if you wanna be cool - come up with real innovations like an electric car a reusable space rocket.

But putting that brick in my living room to beam charge an obsolete device like a smartphone - 😆 thanks for that creepy sci-fi pseudo marketing BS
 
Neat in theory, but seems like a waste of energy too. How many watts are being consumed continuously to beam mm Wave energy into a space so that the portion your phone receives equates to 5W. What is the watt/hour consumption of this device I wonder? It it smart enough to detect if the device is in the beam, and if not, stop transmitting energy?

Person charging Xiaomi phone be like

So that will always charge the mobile if you are working close to the station?
Do that will not inflate the battery like I had with some of my devices on my devices wall?
 
5W actually charging at the device level? or output of the sending device? There are no technical details in the article.
I would be very concerned about the efficiency of this thing, while something like Qi is probably 80%, this is nom way near to that, I'd be impressed if it were 50%. At that level, you definitely need to do studies for health concerns, and quite frankly, given that it is from China, I wouldn't trust it a bit.
 
Anyone have any efficiency data on these technologies? Love the convenience but I suspect it's very lossy.
nothing mentioned in the linked article, but I would be VERY impressed if it were 50% ... article does state that range is several meters (whatever that number might be, 3? 4?) and that obstacles have no influence on efficiency ...

It will be very wasteful, even if it is using something like beam-forming.
 
Great idea and concept but I'm way more concerned about what all that radio frequency in my house is doing to family and pets, as well as my other pieces of tech and wi-fi.

All these U1 chips might finally find a use for themselves if they wedge this tech into, I dunno a HomePod or something.
 
perfect. let’s waste even more energy.
inverse square law intensifies
