That said, it's important to buy the best portable air conditioner for your room size, otherwise your unit will be working overtime to try and cool a too-large space. Sadly it doesn't come with a window kit included, or a remote control – but WiFIi connectivity means you can control it from your phone instead, a really handy feature.

Beyond that, this air con unit is bulky and heavy. It weighs in at 31.5kg, one of the heaviest units we've tested, so carrying it upstairs is a definite two (strong) person job. But, it looks good. And its curved front, minimal design, and gloss finish all make it far more unobtrusive in a room than you might expect. The build quality is also solid and robust. As an electrical appliance, portable air conditioners will cost money to run, with larger and more powerful units (that means a higher BTU) generally using more energy than smaller units.Window Kit Included: We have included two easy-to-install window venting kits with our AC unit to fit either slide or hinged windows using the step-by-step instructions provided. Its space-saving design also ensures minimal. You might also want to consider whether you want your portable air conditioner to come with a timer, remote control, or WiFi connectivity. In our tests, similar to the MeacoCool MC Series 7000BTU Portable Air Conditioner and AEG Comfort, it managed to cool a 4.5m2 room by 2°C in 10 minutes, and despite the manufacturer stating its noise level is 65dB, our reviewer found it much quieter than the Meaco model, comparing it to the AEG Comfort on this front. A powerful portable air conditioner that looks good, is easy to use, is relatively quiet in comparison to most, has WiFi connectivity, and – most importantly – can cool down a room fast, as long as you don't mind its slightly higher running costs. It has some downsides, but only in keeping with most portable air con units, in that it's heavy which makes it not quite as portable in reality as its name may suggest.However, the build quality is good, it has easy-to-use controls, and its design is unobtrusive – although we think the AEG Comfort just pips it to the post in the style stakes by offering a sleeker design.

Powerful Cooling: 9000 BTU/h cooling capacity providing cooling down to 16°C in medium to large homes, living rooms, bedrooms, and offices. You're likely opting for a portable air con unit because you would like it to be... portable! However, in reality, even the best portable air conditioners are both bulky and heavy, weighing from 20kgs for a smaller 'lightweight' air conditioner to 30kgs+ for more powerful units.

You also get a lot of extras with the Pro Breeze 9000 BTU 4-in-1 Portable Air Conditioner considering its price tag, including a remote control, timer, 'night' settings, and WiFi connectivity. Although some reviewers mention its Smart features leave a little to be desired. Cost Effective: The advanced sleep mode keeps you cool while minimising overnight energy consumption by gradually reducing fan speed. In an ideal world, all of our homes would be better insulated and able to remain cool in the summer without the additional energy use or expense of an air conditioner.However, for many of us this isn't the reality, and if you struggle to keep your home at a bearable temperature during the summer months, then a portable air con unit could help.
