I think in theory general case I’d rather be able to find it easily than have more charge when it’s located. You can generally use one while plugged in.

Anyway, the root of their issue is other people unplugging it, which is a bigger issue than just the iPad. Still if you turn it off before pugging it in the iPad would have ~full charge if someone unplugged it. They hold charge for months on store shelves.
