any good powerbanks for laptops?

[Rubixxxx]

my battery life of my laptop is running pretty low (2h from 100 to 0). Does anyone know a good powersupply that doesn't cost a arm and a leg and that works for asus?

does your asus charge through type c? I bought one from ugrean for $90 maybe that does 65watt

Nope. There really aren't gonna be any inexpensive battery banks that output through a barrel jack. That's a specialty item and thus you'll pay specialty prices.
One option would be replacing the battery.
