Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Also have one of these and it works really well. It’s very heavy though, so don’t expect to be lugging it up and down the stairs. Portable just means it has wheels.
Pinguino Compact. Sorry you’ll have to google the size ratings I can’t remember them off the top of my head. It cools our bedroom/ensuite down really well.
Delonghi penguio compact as supposedly quieter, it is decent on the lower setting. Got mine from Very due to 20% off but if you’re thinking about it for next week just go for whoever has them. in stock. I have also heard good things about Meaco? I had to buy a piece of acrylic with a cut out for the ac hose due to the shape of the windows but it is the neatest solution I’ve found. If you’re more DIY than me you can probably do it yourself but I found someone online to make mine. Think it’s worth it, glad I don’t have to do the dance each summer about whether we should get one anymore. When we move in a few years we’re likely to get ac units properly installed so if you have the budget and aren’t likely to move any time might be worth just going straight for that as summers are only going to get hotter.
I have a Delonghi Penguino, they are on the more expensive side but well worth the investment, it is our third year with it and it keeps our living room super chilled, it is bliss 😎
I’ve been using the Pinguino, and while it’s effective, it takes about two hours to cool my room from 29 to 25 degrees. It’s fairly quiet—though in quiet mode, the fan is very muted, but the compressor remains audible. Tonight, I have a Pinguino running in my bedroom, alongside my children’s units: one is a Meaco 9000 BTU, which is a bit noisy but cools quickly—about three hours from 30 to 25 degrees—and the other is a Silvercrest 7000 BTU, which is quieter due to its smaller size, taking around 3.5 hours to cool the same range. Looking ahead, I definitely plan to invest in split units because, with global temperatures rising, it’s only going to get hotter. Plus, I dislike having to stick the vent hose out of the window, especially since the sealing nets don’t always line up perfectly. Hot air often leaks back in through open windows, counteracting the cooling effect. With the split units, you can still run them when tropical weather suddenly throws shower vs portable units you will get the window sill wet. Also when people burn wood in their garden you can't have the window open so no aircon vs split units you can and no smell I am guessing. I could be wrong on this ladt point. If anyone could confirm this, TIA. Edit. UK based.
I got a Delonghi Penguino two years ago, I'm sitting 4 feet in front of it and it's noisy, power hungry, and does nothing to cool the rest of the room, but to me it's worth it because my immediate space is 24 not 34.
