The landscape for mini AC units changed dramatically when portable cooling technology got smarter and more efficient. Having tested all these options myself, I can say the key is to find a unit that balances power, ease of use, and quiet operation. The BLACK+DECKER 8,000 BTU Portable Air Conditioner with Remote impressed me with its combo of cooling capacity and portability.
