Update: As predicted, a bunch of these have now sold out (and especially those over 10,000 BTU) — I've updated the list below to show those still available to buy.
Brace yourselves: we're heading for another heatwave. If you're wondering if it's time to invest in some portable air conditioning, I'd suggest getting on it sooner rather than later. Units start selling out every time the temperatures begin to rise, and stocks have barely had time to replenish after the last heatwave a few weeks ago. Below, I've rounded up the models that are currently available to buy. I've stuck to trusted appliance brands — there are more options available at Amazon from brands I haven't heard of, and if you want to risk it with those, that's on you.
