I sold it because I am not on all anymore but my GPD Pocket 2 was much smaller (it would fit in the pocket of my pants) and it would charge on a 20W smartphone usb-c charger.

My wild guess is if you are taking a laptop with you, you are likely to use some kind of bag so having a charger around is no big deal, especially if you are in someone's home. And if you are in a social place, you won't stay connected for hours as it is pretty antisocial, you are likely to have to have several phone calls and you will be asked to leave anyway so you usually fix the problem quickly and if not possible you just pay the bill and go back home.
