Co2 and portable ac in 8x8

I recently had to take my room down when landlord saw 3 ton split unit outside. So now I’m in a 8x8 gorilla tent. I have Anden dehu ran by trolmaster unit. It’s time for a portable ac but I don’t know which one to grab. Please only experienced feed back.

did you put a 3 ton split on your landlords house without him knowing ?
