I know you said you don't care about camping, but I have to point out it's simply not as big a problem as people like to imagine either. I take a battery to charge my phone for maps anyway. The big difference between charging my watch camping, and charging my watch at home, is when I'm camping, I put it on the charger and take it off when it hits 80%. I don't just leave it there while I sleep.

5-8 days on 1 or 2 powerbanks is normal. Most people hiking more than that are going to find somewhere to stop and charge (and restock food) at least that often anyway. Truly hitting wilderness for 2+ weeks is the actual edge case where I'd want to leave my watch at home.
