  • 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 preferred temperature — even during a sustained summer heatwave.

  • No need to buy separate devices: Air conditioner, fan, and dehumidifier combined in a single unit — complete control over your indoor climate all year round, without the clutter of multiple appliances.

  • Quiet enough for the bedroom: A minimum noise level of 55 dB and a dedicated sleep mode mean the Grandbreeze Pro 14K runs unobtrusively in the background — whether that's the bedroom, a home office, or a living room.

  • Cool air waiting when you get home: The 24-hour timer — programmable in 1-hour steps with both on and off options — lets you schedule cooling in advance, so you never walk back into a stuffy room.

  • Ready to go in minutes, wherever you need it: Castors, a telescopic exhaust hose, and a window sealing kit mean the unit is fully operational in under 10 minutes — no fixed installation, no tools, and simple to move between rooms as needed.

Product description

When the heat refuses to let up and a good night's sleep feels impossible, the Klarstein Grandbreeze Pro 14K changes everything. With 14,000 BTU / 4.1 kW of cooling power, it handles rooms up to 65 m² — no installation, no fuss, no tradesperson required.

This is a genuine 3-in-1 unit: portable air conditioner, fan, and dehumidifier, all in one compact appliance. Set your preferred temperature anywhere between 18 and 32 °C and the Grandbreeze Pro 14K holds it there, even during a prolonged heatwave. The built-in dehumidifier removes up to 1.8 l/h of moisture from the air, tackling that heavy, oppressive humidity that makes summer indoors so uncomfortable. Energy efficiency class A keeps running costs in check even during extended use. And when you need it in the bedroom, the sleep mode keeps noise down to 55 dB — quiet enough for a proper night's rest.

Castors underneath mean you can move it from room to room in seconds. The telescopic exhaust hose and window sealing kit vent warm air straight outside — compatible with standard window frames, no structural work needed. The LED display shows both target and actual temperature at a glance, and the 24-hour timer can be programmed in 1-hour increments as either an on or off timer. Come home from work to a room that's already cool — without leaving the air con running all day.

The Grandbreeze Pro 14K is ideal for rented properties where a fixed installation isn't an option, as well as home offices, playrooms, and small commercial spaces up to 65 m². Unbox it, fit the hose to the window, plug it in — and it's up and running in under 10 minutes. It also makes a genuinely thoughtful gift for parents, elderly relatives, or anyone moving into a new flat.

Three operating modes, four fan speeds, and a dedicated sleep mode give you complete control over the climate in any room up to 65 m². Order the Grandbreeze Pro 14K today and feel the difference from the very first evening.

Klarstein Grandbreeze Smart Potable Air Conditioner 16000 BTU Beast Of A Cooling Machine!!!

I already had a DeLonghi portable air conditioner with 11,500k BTU cooling capacity which I regularly move from my living room to my bedroom every night during the heatwave seasons which unfortunately not powerful enough for my 270sq ft living room but perfect for my 168sq ft bedroom.

I now recently bought the Klarstein Grandbreeze Smart 16000 BTU Portable Air Conditioner Black to use in my living room only. After using this for a couple of hours, it chills like a pro! Dropped 28°C to 22°C in 20 mins on High, so cooling is top-notch. The 16k BTU output is no joke — it’s a proper unit.

Noise is where placement matters:
- On High @ 1m = 61 dB (like a fridge + fan).
- On Low @ 1m = 58dB also (like a fridge + fan).
- On Sleep mode = 48-50 dB (library quiet).

Pros:
- Serious cooling power for the price — chills a 30m² room no problem_
- App control + WiFi works well from Cheltenham to phone abroad_
- Build feels sturdy (vs cheaper 12k models)
- Comes with decent window kit + remote
- Drainage is easy via hose tap_
- Timer + multiple modes (Eco/Turbo/Sleep)

Cons:
- Hose is short (1.5m), don’t expect to move it far from window.
- No condensation tank level indicator (just a red light when it’s full)
- Klarstein’s UK support is email and live chat on website only (no phone help)

Overall: If you’ve got space + position it right, this is a beast. 5 stars from me *****

Très bon produit, conforme à la description. Par contre je n'ai jamais réussie à le connecter au wifi et l'associer sur l'application. Si quelqu'un à réussie je suis preneuse d'un peu d'aide :)

Die Anlage wird über einen unseriösen Versanddienstleister versendet "trans-o-flex Express GmbH" wo mir einfach jeden Tag der Aktuelle Tag als Liefertag angezeigt wird. Die Telefonnummer auf der Klarstein.de Rechnung exestiert nicht. Der Kundenchat hat nur einen Bot der Rückrufe anbietet die es wiederrum nicht gibt. Seriös sieht anders aus.

Die Kühlleistung der Klimaanlage ist meiner Meinung nach doch sehr ordentlich. Bei meiner offenen Dachgeschoss Wohnung 58 qm Fläche ( mit teil offenem Deckenbereich zur Dachgaube hin ) lag die Innenraumtemperatir bei 34°. Die Klimanlage hat es relativ zügig geschafft auf 30° runter zu kühlen ( bei 39° Außentemperatur wohl gemerkt und meine Wohnung war mit einer Wärmelast schon vorbelastet durch die 34° ). Die Klimaanlage war dann auch sehr gut in der Lage die 30° zu halten bis zum Ende des Abends. Sobald es draußen kälter wurde kühlte die Klima auch wieder herunter. Sie lief unter extremen Bedingungen 39° Außentemperatur das darf man nicht vergessen
