A20 X not charging

Heya! I just got my shiny new A20 X. It arrived with 0% charge out of the box and doesn't seem to be accepting any charge. I've tried the included cable plugged into my PC, my phone charger, and my Steam Deck charger. G Hub says it's charging but I've kept it plugged in for about 90 minutes now and it's still at 0.

I tried googling but all I'm finding is A20 stuff, not A20 X, and of course google discontinued the quotation mark trick in favor of their AI hallucinations.

G Hub is telling me to do a firmware update, but when I try to do that, it refuses because the battery is low.

Is there anything I can do? I found a button combo to hard reset an A20 but I can't find anything like that for the A20 X and the included manual doesn't seem helpful at all.

EDIT: I put a new battery in it and that fixed it. I just got a defective unit.
