Too hot to sleep?
Find a portable AC you can get this week.
When the heat hits, you don't want a 40-tab research project — you want the right unit, at a price checked at a real United Kingdom retailer, that ships fast. We compare the shortlist so you can buy once and cool down tonight.
Proper compressor cooling that actually drops the temperature — not a glorified fan.
Low-decibel units you can run all night — ranked by measured noise.
Won't cool the air, but a decent fan takes the edge off for a fraction of the price.
Three questions.
