Iceblock Smart 12000 BTU Portable Air Conditioner White

When the temperature outside refuses to drop and you've got a large open-plan space, a bedroom that doubles as a home office, or a hotel room pushing 56 m² — you need more than a desk fan and wishful thinking. The Klarstein Iceblock Prosmart delivers 12,000 BTU / 3.5 kW of serious cooling power, handling rooms from 42–56 m² without a single screw in the wall or a call to a tradesperson.

This is a genuine 3-in-1 unit: portable air conditioner, fan, and dehumidifier in one compact mobile system. Set your preferred temperature anywhere between 16 and 31 °C, and let the airflow — up to 320 m³/h — do the rest. Energy efficiency class A keeps running costs up to 30% lower than standard-class units, and at a rated power of 1,345 W, it won't make your electricity bill wince even on the hottest days of the year.

Smart control is built in from the start. The Klarstein App gives you full remote access to temperature, mode, timer, and status — whether you're at your desk, on the commute, or away for the weekend. Amazon Alexa and Google Home are fully integrated, so a quick voice command is all it takes. The unit uses R290 refrigerant (160 g), a high-efficiency refrigerant with a low global warming potential. Installation is as simple as it gets: a telescopic exhaust hose and window sealing kit are included, so you can be up and running in minutes with no permanent fixtures.

The 24-hour timer (in 1-hour increments) lets you schedule cooling around your day. Programme the Iceblock Prosmart via the app before you leave the office, and walk into a perfectly cooled home. At night, the sleep mode automatically reduces fan speed and steps down the cooling output after 1 and 2 hours — so it settles into the background while you rest.

The Klarstein Iceblock Prosmart is built for the way people actually live: large rooms, changing schedules, and no appetite for complicated installs. Order today and stay cool wherever summer finds you.
