Product Information

But can you really make the argument for splurging on an electricity-guzzling portable air conditioner? It’s modern, covers a large space, is easy to fill with water, can be controlled using the Princess Home app and of course, kept us cool in nearly 30C heat. We're particularly impressed with its high extraction rate of 24 litres per day and its high cooling power of 9000BTU.

Its power helps a lot: we measured air speed at 4m/s from 15cm away making this one of the most powerful fans that we’ve tested.Every model is then scored according to its performance, ease of use, design and product information. Innovative items like robot vacuum cleaners and wine coolers are among her favourite tests to date, and her most notable accomplishment is toasting 360 slices of bread in a determined bid to find the best toaster. I am a light sleeper which unfortunately means this is far too loud for me to even try and sleep with.

Luckily, to save yourself from having to take a punt on a less than reputable brand, we have years of expertise under our collective belts when it come to putting all sorts of fans through rigorous testing to see how well they perform in real-world use and whether their feature sets meet the claims laid out by their respective manufacturers. In reality, I remain unconvinced that such modes feel any better to the Standard mode, which uses a constant fan speed. Its only significant drawbacks are that it’s awkward to remove the water tank and filter block for cleaning and that it puts out around 60dBA of noise at its highest speed. It’s not much to look at and the whine from it means that the Princess Smart Air Cooler isn’t great for a bedroom.It’s not the most stable of units, and it had a smaller oscillation capacity at 70 degrees, but testers liked its digital room temperature display. Some models also feature built-in humidification, putting a little moisture back into a dry room, which can make it feel more comfortable (as long as it’s not hot and humid in there already).
