The Inverse Square Law is coming for your charging efficiency and will take no prisoners. 6G will be everything connected by wires once again as if they discovered it yesterday. It'll be funny!
It's great to have a backup to the USB port so the device doesn't become useless if anything happens to it.
The annoying thing is the stuff that really would benefit most from wireless is lower power, less often used stuff, which never actually has it...
A Qi charging flashlight would be pretty nice. But almost nobody does them.
I've thought about trying my hand at circuit design by making a Qi charging beard trimmer with a supercap "battery", but I suspect that might be jumping into the deep end.
In that case it’s probably more due to a particularly inefficient DC fast charger. (It’s been a long time since I watched it so I might not remember the details right.)
In the end it doesn’t have to be exactly as efficient as wired charging, and probably never will be for a good implementation of a wired charger. It only has to be so close that you don’t care about the difference.
I don’t think the inverse square law is very relevant on these scales. Electromagnetic radiation can be focused.
The solution from the article seems more of a meme and then I saw it's an actual product from Dragon's Den which explains everything.
