I actually do this. I have a small power bank I keep the mouse hooked up to, and when it falls low enough it taps into it. Every few weeks or even a month I recharge the bank up. But wires being a problem will depend on your setup and desk real estate. This doesn’t bother me, but having a wired keyboard would lose some space, so I’m glad for my wireless there. And that’s even less of a hassle, as it’s still running off the original batteries it came with years (and years!) ago. Makes sense, there is very little power usage there being a boring old Logitech non-backlit keyboard.
