I used the Princess Air Cooler in my office for the review period. It arrived just after the ridiculous temperatures we have seen recently, but my office is still a reasonably unpleasant 25°C+. Humidity is typically 50-60% which is a touch higher than the ideal humidity range. I am sure most people know the difference already, but it is important to know how an air cooler is different from air conditioning as some people get confused/misled. I put the Princess Smart Heating and Cooling Tower through my standard tests. Starting with the regular fan, I measured air speed at 3.08m/s on maximum setting from 15cm away, falling to 1.31m/s at 1m. That’s not bad, although I have tested more powerful fans.

I am James, a UK-based tech enthusiast and the creative mind behind Mighty Gadget, which I’ve proudly run since 2007. Passionate about all things technology, my expertise spans from computers and networking, to mobile, wearables, and smart home devices. in-1 Appliance - The Princess Smart Mobile Air Conditioner is a multi-functional appliance with three modes - Air Conditioner, Dehumidifier and Fan. Such versatility allows the unit to be used all year around, whether during the hot summer, wet/cold winter or in more moderate spring/autumn weather. With some air coolers, there’s a risk of adding to the room’s humidity, which can be a problem if it already suffers from excess humidity. Plus, where water tanks are open inside the cooler, there’s also a risk of spillage – which can be a worry if you’re using a desktop model plugged into your laptop or PC.Air coolers have a bad reputation for increasing humidity, and they are less than affectionally called swamp coolers. They will have reduced performance in humid environments, and the UK is reasonably humid. We also like the fact that you can clean the filter under the tap or in the dishwasher, and that the illuminated side panels can be set to glow with a choice of seven colours if you fancy a little mood lighting. While it could be easier to remove the filter and get the water tanks in and out of place, for sheer value and convenience, this cut-price compact cooler is a winner. Dehumidifier Mode - When in dehumidifier mode, up to 1 litre of water is extracted per hour, equivalent to 24 litres per day. This of course depends on the humidity of the room. Such a high extraction rate is ideal for rooms with extreme damp, condensation and moisture issues.

An air conditioning unit is completely different, and it works a bit like a fridge, expelling the warm air outside. They are big, heavy, noisy, expensive to buy and expensive to run, but they offer vastly superior cooling performance. Features Set up was relatively straightforward and identical to the Princess Smart Air Purifier. With both devices, it took me two attempts to get them to work, I am not sure if this user error, my phone or the Princess app. I measured power consumption at a maximum of 1983kW on Heat mode (in fan-only mode, power consumption topped out at just 28.8W). Given the average cost of electricity in the UK (18.9p per kWh), this means that the Princess Smart Heating and Cooling Tower will cost a maximum of 37.48p per hour to run. Note that next to central heating, all electric heaters are comparatively expensive to run. The Princess 358640 Smart Air Cooler utilizes advanced cooling technology to provide efficient and effective cooling for your home. Control your Smart Air Cooler with the app and voice control or choose the conventional way by using the control panel or remote control. Still, in Alexa, the Princess Smart Heating and Cooling Tower appears as a proper device, so you can use it in routines. PerformanceThis cheap cube desktop cooler doesn’t have a lot of bells and whistles, but it’s a good way to chill your fevered brow while you’re plugging away at your desk. Its two removable 300ml tanks mean it doesn’t constantly need refilling, and you can freeze them if you want some extra cooling. The three-speed fan gives you options from subtle breeze to full-on gusting, and on the lowest setting it’s quiet enough that it won’t disturb you while you work. In my academic pursuits, I earned a BSc in Information Systems Design from UCLAN, before advancing my learning with a Master’s Degree in Computing. This advanced study also included Cisco CCNA accreditation, further demonstrating my commitment to understanding and staying ahead of the technology curve.

Once connected, the app covers all of the basics. In Fan mode, you can adjust the speed, in increments from one to 10. Switch to Heat mode and you get four options, plus you can set a target temperature, too. Both heating and cooling modes support oscillation – and the sleep timer, which you can set in one-hour increments up to 24 hours.Additionally, it should be easy to use and maintain, with features like air cleaning filters, automatic shutoff and timers. You’ll also want to make sure it’s energy-efficient. The more powerful units use more energy, although all air coolers are much cheaper to run than air conditioners.”
