I took a look around and a lot of comments mentioned to get one that uses ‘LiFePO4 Batteries’, and that seemed like a reasonable requirement.
They’re supposed to have a longer life span, be safer, light weight, and better charge/discharge efficiency which is in line with what I’d be looking for.
Some brands/models that I saw recommended:

edit, added an image of what I’m referring to
If price is your main concern make one yourself. Specially if you don’t need 110
-
buy a 12v battery of your choice (deep cycle are best, but car batteries will do in a pinch, UPS batteries if you want small)
-
buy a tool box of adequate size for your battery, allow for extra room
-
order a “float charger”
-
Order USB and cigarette lighter ports as desired
-
wire it all up inside the toolbox
I’ve made a few with minimal effort, they’re great for camping and my latest one even allows me to jump start a car
There are plenty of guides out there with more detailed steps
