I have one like that and so do my parents. But they're much less effective than classic split AC with an outside unit. A regular split can cool a bigger room to 24 even when it's 38 outside and is basically completely quiet. A portable AC cools down smaller rooms to ~27 when it's 38 outside and is noisy (50-60 dB).

That's cause you got the cheapest one and think all of them are like that. They come in different power levels and you can in fact find ones that are quiet.

People don't know which to buy. I got a really big one that doesn't make a lot of noise. I think on dehumidify it can suck 1.5 liters per hour out of the room. I think this because with 98% humidity the 0.5 liter tank is full in <20 minutes. The tank isn't removable, it has a lid 3 cm above the floor. Just low enough that one cant leave a large enough container under it.

Some of them use the waste heat to evaporate any accumulated water and have it come out of the heat exhaust as slightly humid air. The one I got when I lived in Hawaii had a hole where water would drip out of and you could attach a hose to it.
