I find mine works fairly well, it's a 12k BTU unit.

It has one exhaust duct. It pulls in warm air from the room it's in, cools part of it and pushes it back into the room, the rest is used to cool the condenser and that hot air is sent outside through the duct.

It does have another tube, but it's a small hose to drain the water from condensed humidity.

Until the room is cooled enough that you are using the air you have paid to cool, to cool the evaporator. Portables are shit.

That's one of the main reasons their efficiency is lower.

A split unit, especially with an inverter motor, can be 50% more efficient, much less noisy and cool more evenly.

That said, portable units do work. For people who are unable to get a proper split unit, then don't rule out a portable unit.
