Re: Charge by wire
I don't see the point of wireless charging
Use in a domestic setting might be moot, but there are plenty of settings where it makes a lot of sense, especially public spaces where charging is provided as a matter of courtesy such as airport lounges. The cabling for charging mats is simpler and less fragile than providing more powerpoints, though obviously USB-ports are also good if also a potential security risk.
If I'm travelling for any period where I think I need a device while it's charging I use a powerbank.
