Okay, so this Framework laptop I'm typing on can power from any of its 4 USB-C ports. Ignoring that it already has a battery (you can buy just the motherboard and a non-laptop case), doesn't that work around this neatly?
Plug one USB-C directly to wall, plug second USB-C to powerbank.
For absurdity, repeat until you have a highly available array of 3 powerbanks. You can even put them on timers so you don't need pass-through charging!
