Cools even the largest rooms reliably: With 12,000 BTU / 1.35 kW of cooling output and an energy efficiency class A+ rating, the Grandbreeze Eco 12K handles rooms up to 56 m² — even through prolonged heatwaves.
Full control over your room climate: Air conditioner, fan, and dehumidifier all in one unit — tackle heat, humidity, and stuffiness without buying separate devices or additional accessories.
Quiet enough for a good night's sleep: A dedicated sleep mode gradually reduces the temperature by 1 °C/hr over two hours, then holds it steady for a further six hours — so you drift off comfortably and stay that way until morning.
Set it and forget it cooling: The 24-hour timer is programmable in hourly intervals with separate switch-on and switch-off times, so your room is always at the right temperature exactly when you need it.
Ready to go wherever you need it: Built-in castors let you wheel the unit from room to room in seconds, and the telescopic exhaust hose has the whole setup running in under 10 minutes — no fixed installation, no tools, no fuss.
Product description
When summer turns your living room into a sauna and the bedroom feels unbearable by 10pm, you need cooling that actually works. The Klarstein Grandbreeze Eco 12K is a portable air conditioner that tackles rooms up to 56 m² — no drilling, no installation appointment, no waiting.
With 12,000 BTU / 1.35 kW of cooling power and an energy efficiency class A+ rating, the Grandbreeze Eco 12K keeps large spaces genuinely comfortable without running up your electricity bill. Set your ideal temperature anywhere between 18 and 32 °C, and let the built-in dehumidifier strip out that oppressive summer humidity at the same time. Airflow of up to 460 m³/h means cool air reaches every corner of the room, not just the spot directly in front of the unit.
The telescopic exhaust hose and window seal kit are included — hot air goes outside, cool air stays in, and the whole setup works with standard window frames without any modifications. Built-in castors mean you can wheel it from the lounge to the home office to the bedroom in minutes. The LED display shows both target and actual temperature at a glance, and the 24-hour timer means you can come home to a room that's already been cooling down for an hour before you walked through the door.
Flat, house, office, or small studio — the Grandbreeze Eco 12K is ready to run in under 10 minutes. Unbox it, fit the hose to the window, plug it in. No engineer, no waiting list, no fixed installation. That also makes it a genuinely thoughtful gift for parents, older relatives, or a new home move.
One unit, three jobs: air conditioner, fan, and dehumidifier — no extra kit required. The combination of 1.35 kW cooling output, a quiet sleep mode, and proper portability makes the Grandbreeze Eco 12K one of the most practical solutions going for rooms up to 56 m².
Order today and stay cool all summer — on your terms.
