This.They're all noisy and really heavy but do help to provide sufficient cooling for the room.
Those portable units are just inefficient.
I still have an inventor chilly I bought last year (don't know what to do with it) but it was rubbish.
Yes it did cool the room eventually, but it took forever, cost more in electric, was really noisy and created negative pressure which just sucked warm air into the room again.
There was no way I could have slept in the same room.
This.
On hot days if we want a cool bedroom, we leave it on in the afternoon and turn off as we go to bed, seems to be the best way.
I don't think they're that much, our electricity increased around £1-2 per day when the weather was really hot and the AC was on a good 6-8 hours. Perhaps if it's on 24/7 but there isn't a requirement for that really on a portable.You're talking £7-10 a day for some of these portable ones on average which is pretty nuts.

Depends what temp you set it to and how big the room(s) are you're trying to cool. If you have it on 16c or something it'll most likely never get a room down to that temp so it'll be running flat out. I'd rather have it set to 22-23c so it just ticks on and off and makes the rooms more comfortable without costing the earth. Mine is one which extracts straight out through the wall (https://www.olimpiasplendid.com/airconditioning/without-outdoor-unit) rather than portable but same principle. At the moment if I have mine on from midday to late evening its £1-2 a day. I find by 9-10pm its cool enough outside to open the windows and let a breeze in.Seems to vary quite a bit. I'm not using one but a bloke at work uses one every night once it starts getting warm between 10pm and 8am and he worked it out as £4 in electricity cost.
My portable one is listed at being roughly 250% efficient (2.1kw of cooling for 800w of input), i know proper splits will be better but only up to around 500% at best, so realistically it'll only be twice as efficient.Split is probably 5 times more efficient than a portable.
Bought a cheapish £200 unit at the start of the summer and its not done what I'd hoped. Was hoping to be able to turn it on for an hour when I got in from work when the house had been shut up/before bed to cool a room but as soon as you switch it off the temp rises again within 10-15mins. I probably expected to much but its certainly too loud to have continuously running and use the room imo so wasted money.
