Overview: Oh no. It’s a new version of a well-established product that trades efficiency for convenience. But this time, it’s more than just being cool. It’s about cooling. Seriously, either we need to get more awareness of how dumb single-hose portable A/C units are, or we need to just use window units whenever possible. While I know that there are times a portable unit is the only option (remember, I’m in that boat), it seems that only very high capacity, premium machines have the facility to use two hoses. Which is frankly stupid but then again that’s what I’m trying to tell you now.
