Take the heat out of bedrooms, living rooms, home offices, and conservatories up to 50m² with this powerful 12,000 BTU smart portable air conditioner. Three modes — cooling, fan, and dehumidifier — handle every summer scenario in one compact unit. Cooling mode drops room temperature fast and holds it at your chosen setting automatically. Dehumidifier mode removes up to 1.2 litres of moisture per hour, tackling the sticky, humid air that makes UK summers feel uncomfortable even when it isn't that hot. Fan mode keeps fresh air circulating on milder days without the compressor running, saving energy. No engineer, no drilling — the window kit fits most standard UK sash and sliding windows and takes under 10 minutes to set up.
The built-in WiFi connects to the SmartLife app, giving you full control from your smartphone wherever you are. Adjust temperature, switch modes, set the fan speed, and programme the 24-hour timer remotely — so your room is already cool when you arrive home, not half an hour after. Two adjustable fan speeds and an automatic vertical swing function distribute cool air evenly throughout the room rather than blasting one spot. The highly legible LED display and included remote give you complete manual control too. The window kit is one of the most straightforward on the market — slide in, seal, and it's done.
Compact and genuinely easy to move. At 23.5kg it's lighter than most comparable units, and with smooth-rolling caster wheels and deep, well-placed carry handles it's simple to shift between rooms as needed. The energy-efficient rotary compressor automatically reduces power draw once the set temperature is reached, keeping running costs sensible. The washable air filter is easy to remove and clean, and a metal control box provides additional safety against overheating. A 1-year manufacturer's warranty is included as standard.
