Your Wi-Fi also needs a cable if you want to be pedantic.
The benefit is that there is no overhead involved, in theory you don’t even have to think about charging your phone ever again. When it’s not in use, just leave it on some of the dedicated places around the house and office that provide wireless charging.
Anyone got an idea of cost? Of course this is going to be brutal, but it’s literally ten times what I have in my NAS, in a size slightly longer than a 2.5" drive.
