Obligatory Technology Connections video: https://youtu.be/_-mBeYC2KGc
tl;dr - these are all loud and really inefficient very poor cooling performance. If you can convert it into a twin duct solution (see OzB link above) then they start approaching reasonable efficiency.
But for fifty bucks I'd probably buy one myself 😅

I'm sick of seeing that video linked. These things are fine if you don't have an alternative, and don't mind the electricity cost. They can actually cool a room, unlike a fan. When the humidity and temp is up, these are a lifesaver.

I have suffered through a long, hot muggy summer working from a home office in the top floor of a rental property with one of these things blasting away in an attempt to stay cool, and it did help, somewhat. So I totally get your sentiment.
But the point of the video is not to say that they don't work, or ridicule those who have no other option. In fact he says quite the opposite. The point is, at retail cost at least, if you have any way to spend your $ on a split system, then that's generally money far better spent: it will cost you far less and do a far better job of cooling. For example, if you rent (and plan to stay), you could offer to pay half to get a split system installed.
At an RRP of ~$400-500 that reasoning holds. At $50 the argument evaporates somewhat. Pun intended.

It would be like making a video about how a fan actually increases the temperature of a room instead of lowers it, rendering it inefficient.
If a person is buying a fan, then clearly they aren't able to get an air conditioner. If a person is buying a portable air conditioner, then clearly they aren't able to get a heat pump.
The point is redundant.
Anyway, I bought the $150 hot/cold one (I think the brand is Kensington) that was posted on here years ago, and it's still saving me during summer. It knocks 10°C off my room temp, allowing me to get to sleep easy

@Plug: Haha try explaining to people that a fan in a closed off room will actually increase the temp is a hard task.

i knew the video before i clicked on it. Yes a fan just circulates air temp, you want to reduce the humidity to make it easier to cool or heat a room.

Unless you want to leverage your bodies ability to use evaporative cooling by introducing a fan.
It wont cool the room but you will notice a difference.- 2
It gets linked for a good reason.
Those units are rubbish. They literally fight against the heat they produce themselves.

Can you explain the two duct thing please?

Look at the comments on OzB (if you haven't already)
Googs AI overview
Single-hose portable air conditioners use indoor air to cool internal parts and push it outside, creating negative air pressure that pulls hot air back into the room. Dual-hose units use one hose to pull in outdoor air for cooling and a second to exhaust heat, balancing room pressure for faster, more efficient cooling
- 2
Yeah, with a bit of hackery (cardboard and duct tape in a pinch) you can convert these into more efficient systems by pulling outdoor air into the intake via ducting (instead of using already-cooled indoor air) and then when it's vented outside you're not getting the negative pressure effect. Cool air stays inside where it belongs.
Honestly, why all portable air conditioners don't already do this out if the box is a mystery.

@CheapAzChips: If its hot outside its easier to cool already cooler air from inside plus dehumidifi ing the air from inside makes more sense than dehumidifi ing air as its brought inside, plus some are reversable for winter so blow hot air in and cold out.
Everyone saying these arent good are looking at it the wrong way, sure they are not as good as a built in one but they are better than a fan (and a fan is better than no fan) i paid way more for mine and its great on a hot day or cooling a room before bed. $50 is a bargain

@quote: $50 is a bargain. No argument there. And I'm not suggesting that you cool outside air, not at all.
Portable units have TWO air systems. Most units pull air from the room for both cycles: one is chilled and sent back into the room, the other is heated and expelled outside. So you're literally heating pre-cooled air and expelling it. To make matters worse, the room then has negative pressure, meaning that warm air from outside is sucked back into the room (under the door, around the closed window, etc).
If you can separate the second cycle from the first, you basically create a split cycle system: on the cool side you suck room air in and blow it out colder. On the hot side (with aforementioned hacky mods) you suck air from outside, dump the waste heat into it and blow it back outside.
You could spend $30-40 on a few parts from the hardware store to make this change and you'll make that back in energy efficiency easily in a month of daily use.

Point the outlet at you and these are great even with all the problems that people bring up about outside air coming in. The issue I had with mine was it was more powerful than the extractor in the bathroom or the kitchen and would make those ineffective when running the portable AC.

On hot dry Akl summer days, I find strategic placements of usb powered humidifiers very handy, which saves us from turning on a heat pump for cooling.
Always replace dirty filters and keep dust off the nozzle after summer to keep them working for years.- 1
