@Xdqwerty, wire is definitely more practical IMO. Hell these days you can charge a laptop over USB, can't charge a laptop wirelessly though. Wireless chargers, even "fast" ones, are only good for slowly charging devices, plus they generate a good amount of heat too
Power banks can be incredible depending on your needs. 1) I have a 100w capable one that can charge my laptop. 2) Same one can also power my soldering iron (though is overkill for it) 3) a BIG power bank I have with an AC outlet on it can power my desktop weed vape during a power outage
