[Used] Grandbreeze 14000 BTU Portable Air Conditioner Black

• Cools even large rooms with ease: With 14,000 BTU / 4.1 kW and energy efficiency class A, the Grandbreeze Pro 14K brings rooms up to 65 m² down to your chosen temperature reliably — even when the summer heat refuses to let up.

• Tackles humidity as well as heat: Air conditioner, fan, and dehumidifier are all built into a single unit. The dehumidifier removes up to 1.8 l/h of moisture from the air, tackling that heavy, muggy feeling that cooling alone doesn't always fix — no extra appliances needed.

• Quiet enough for the bedroom: At a minimum of 55 dB in night operation, plus a dedicated sleep mode that gently steps down cooling by 1 °C/h over two hours before holding temperature steady, the Grandbreeze Pro 14K won't disturb your sleep.

• Cool the room before you even walk through the door: The 24-hour timer — adjustable in 1-hour increments and available as both a switch-on and switch-off option — lets you schedule exactly when your home starts cooling, without having to think about it.

• No tools, no tradesperson, no hassle: The telescopic exhaust hose, window seal kit, and built-in castors mean you can set this up in any room and be cooling in under 10 minutes — no permanent fixtures, no fuss. Move it wherever you need it, whenever you like.

When the temperature climbs and sleep becomes impossible, you need serious cooling power — not a desk fan hoping for the best. The Klarstein Grandbreeze Pro 14K delivers 14,000 BTU / 4.1 kW of cooling across rooms up to 65 m², with no installation, no landlord permission needed, and no fuss.

This is a genuine 3-in-1 unit: portable air conditioner, fan, and dehumidifier in one compact, wheeled cabinet. Set your ideal temperature anywhere between 16 and 30 °C, and the Grandbreeze Pro 14K holds it there — even during a prolonged heatwave. The dehumidifier pulls up to 1.8 l/h of moisture from the air, tackling that heavy, oppressive warmth that a fan alone can't shift. Energy efficiency class A keeps running costs manageable, even when it's working hard through the hottest weeks of summer.

Moving it between rooms takes seconds — just roll it on its castors. The telescopic exhaust hose and window seal kit direct warm air outside through most standard window frames, with no drilling or permanent fixtures required. The LED display shows both your target temperature and the actual room temperature at the same time, so you always know exactly what's happening. The 24-hour timer can be set as either a switch-on or switch-off timer in 1-hour increments — programme it to cool down your home before you get back from work.

Perfect for rental flats where a fixed air con unit simply isn't an option, plus home offices, children's rooms, and small commercial spaces up to 65 m². Unbox it, attach the hose to the window, plug it in — you're up and running in under 10 minutes. It also makes a genuinely thoughtful gift for parents, elderly relatives, or anyone moving into a new place.

Three operating modes, four fan speeds, a dedicated sleep mode that gradually adjusts overnight, and a minimum noise level of 55 dB in night operation mean the Grandbreeze Pro 14K covers every scenario — from a focused working afternoon to an uninterrupted night's sleep. This is flexible, full-room cooling that goes wherever you need it, without any permanent commitment.

Stay cool this summer — order the Grandbreeze Pro 14K today and feel the difference from the very first evening.
