One thing I wonder though is why they’d need to charge a watch on the bus when battery life on smart watches is typically way more than 1 day and you can charge it overnight? I mean each to their own but I would haaate the hassle of charging anything on a bus…

		That’s fair I suppose. That being said, modern smart watches charge so fast there’s surely another way. I also just personally use an old smart watch I have lying around for sleep tracking. I’d still rather buy two $16 smart watches than have to charge one on the bus haha.
