Hurry! Beat the heatwave with these portable air conditioner Prime Day deals before they sell out

This portable unit can cool rooms up to 36 sq ft in as little as 15 minutes. There's a user-friendly LED control panel, remote control, and automatic restart after a power outage. Put it in Sleep Mode and it dials the noise down to 52 dB so it keeps you cool at night without disturbing your sleep. While not silent, that's about on par with the level of noise in a quiet home anyway. Other features include a built-in fan (with cooling switched off) and a dehumidifier capable of removing 55L out of the air each day.

You can save $100 on this portable air conditioner that uses dual hoses for up to 60% faster cooling than a single hose alternative. Utilizing two hoses means the unit can have separate intake and exhaust hoses to cool rooms quickly and efficiently. This air conditioner is Wi-Fi enabled so you can fire it up from your smartphone (or smartwatch) without having to be at home. If you're out on the school pickup, you can have your kid's room down to a nice welcoming temperature by the time you get back. Midea has had to issue A/C unit recalls in the past, but this one comes with a one-year limited warranty from original purchase date.

This one kicks things up a notch in terms of pricing, but the discount is far greater. You can save 38% ($500) on this unit right now for Prime Day. We haven't tested this latest version out but in our review of its predecessor, we noted the best thing about the Ecoflow is that it's actually two devices in one. That's the same for this newer model: While you can use it as a 6,100 BTU cooling portable air con machine in the summer, it pulls double duty as a 6,800 BTU heater in the winter. The battery life has been improved over the EcoWave 2 and it's also gotten quieter, operating at whisper-quiet 42 to 52 dB depending on the fan speed. If you really want to beat the heat (and the cold), this is the product to go for.

It's not a deal, but it is one of the cheapest portable air conditioners that I've seen over the last couple of days. And it's still in stock over at Lidl, but you'll need to check the store locator to see if you can grab one. Going by the specs sheet, this air conditioner is suitable for rooms between 30 and 45m and can set temperatures from 16 to 31°C. The cooling capacity is 7000 BTU and you've got a 1.5m drain hose and a window kit included for venting. At 65dB, it won't be quiet — but it will be cool and it will be cheap.

This guy probably won't stay in stock at Amazon for too long. It works as a dehumidifier and a regular cooling fan as well as its air conditioning duties. As with many of the other items on this list, it's got a programmable timer for you to set schedules by and comes with a window venting kit. It's got a 9,000 BTU capacity and noise levels will hit 65dB. Because it's also a dehumidifier, there's an on board HEPA filter. It's rated Energy class A, too.

B&Q currently have this unit in stock, although delivery isn't an option — you'll have to go to your nearest outlet and pick it up yourself. This is a 9,000BTU unit that comes with a window insulation kit and three different airflow speeds. It can run automatically with a 24-hour timer or you can control it manually with the included remote control. It's got an Energy class A rating and a 2-year guarantee.

The MC Series Pro 9000BTU air conditioner is built to handle rooms up to 26m. Like others on this list, it can also double up as a heater as well as packing in a dehumidifier. It's quiet at 51dB and A-rated for energy efficiency, it costs around 25p/hour to run. You can operate it via the Meaco App or remote for convenience. Includes versatile window kits and a two-year warranty.
