[Used] Grandbreeze 12000 BTU Portable Air Conditioner White

• Powerful enough for larger rooms: With 12,000 BTU / 1.35 kW of cooling output and energy efficiency class A, the Grandbreeze Eco 12K handles rooms up to 56 m² — keeping running costs in check even during extended summer heatwaves.

• Full control over your room climate: Switch between air conditioning, fan-only, and dehumidifier modes depending on what the day demands — one unit does the work of three, with no need for separate devices cluttering your space.

• Quiet enough for a decent night's sleep: Operating from 55 dB, the Grandbreeze Eco 12K runs in the background rather than dominating the room. The dedicated sleep mode gradually reduces cooling by 1 °C per hour over two hours, then holds that temperature for a further six hours — so you stay comfortable without waking to freezing air.

• Arrives when you do: The 24-hour timer can be programmed in hourly intervals with separate switch-on and switch-off times, so the room is already at the right temperature the moment you walk through the door.

• Ready in minutes, moveable in seconds: No fixed installation, no engineers, no waiting — built-in castors and a telescopic exhaust hose mean the Grandbreeze Eco 12K is up and running in under 10 minutes and can be rolled to whichever room needs it most.

When summer turns your living room into a sauna and sleep becomes impossible, the Klarstein Grandbreeze Eco 12K is the straightforward fix. No drilling, no engineers, no waiting weeks for an installation slot — just effective cooling for rooms up to 56 m².

At 12,000 BTU / 1.35 kW and energy efficiency class A, the Grandbreeze Eco 12K keeps running costs in check even through a prolonged heatwave. Set your ideal temperature anywhere between 16 and 30 °C, and let the built-in dehumidifier take the sticky edge off muggy summer days. With an airflow of up to 460 m³/h, cooled 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 direct warm air straight outside, fitting most standard window frames without any modifications. Integrated castors mean you can roll it from the lounge to the bedroom or home office in minutes. The LED display shows both the target and current temperature at a glance, and the 24-hour timer lets you programme the unit to start cooling before you arrive home — so you're walking into a comfortable room, not an oven.

Whether you're renting a flat, working from a home office, or running a small business, the Grandbreeze Eco 12K is ready to go in under 10 minutes. Unbox it, attach the hose to the window, plug it in. That simplicity also makes it a genuinely thoughtful gift for parents, elderly relatives, or anyone moving into a new place.

One unit covers three jobs: air conditioner, fan, and dehumidifier — no extra appliances needed. The combination of 1.35 kW cooling output, a quiet sleep mode, and the freedom to move it wherever it's needed makes the Grandbreeze Eco 12K the practical choice for rooms up to 56 m².
