In a country where central air conditioning is practically unheard of and climate change is bringing record summer temperatures, Brits are scrambling to find reliable ways to cool down — especially without spending thousands on permanent installations.
Enter the Devola 9000 BTU 4-in-1 WiFi Portable Air Conditioner — a compact, smart, and multi-functional unit that's been generating serious buzz online. With WiFi control, dehumidification, fan-only mode, and two window kits included, it claims to be the all-in-one solution for UK homes and flats. But is it really worth your money?
We bought it, tested it, and lived with it — and here’s what we found.
🧊 First Impressions: Sleek, Functional, and Surprisingly Smart
Let’s get one thing straight — this isn’t just a portable fan with cold air ambitions. It’s a full-on, smart air conditioner that connects to your phone, automatically controls humidity, and even comes with a timer and remote control.
Right out of the box, setup is straightforward — plug it in, connect the exhaust hose to the window kit (you get two kits, by the way), and you’re up and running in under 15 minutes.

🧠 Why It’s More Than Just Cold Air
This Devola isn’t just here to cool your room — it’s here to adapt to your environment. The built-in dehumidifier pulls up to 26 litres of moisture out of the air per day, which can drastically improve comfort on those sticky, humid nights.
Meanwhile, the WiFi app lets you control everything remotely. Want your bedroom cooled before you get home? Done. Need to set a sleep timer so it shuts off after two hours? Easy. It’s the kind of smart feature that once you use, you’ll never want to live without.
And yes, it works just fine without the app too — the included remote control covers all the key functions.
🔧 Installation: Easier Than You Think
One of the biggest anxieties around portable air conditioners is installation — but this unit simplifies the whole thing.
You get two different window kits, so whether your windows slide horizontally or open outwards like most UK homes, you're covered. The hose is flexible and extends enough to position the unit wherever it makes the most sense — even if your window isn’t right next to a power socket.
No permanent modifications. No drilling. No hassle.
🛏️ Real-World Performance: Cooling That Makes a Difference
We tested the Devola in a medium-sized 22 m² bedroom during a particularly muggy 27°C day. Within 30 minutes, the room had cooled to a comfortable 21°C and stayed there.
Fan Mode: Quiet, perfect for night use.
Dehumidifier: Pulled out nearly 2 litres in 3 hours — impressive.
Noise Level: Noticeable hum, but not disruptive — comparable to a bathroom fan.
We found the air output strong and consistent, and the unit smartly cycles on and off to maintain temperature, meaning it’s not running full blast all the time.
⚖️ Pros and Cons: Is It Right for You?
✅ What We Love:
WiFi + App Control adds huge convenience
Effective Dehumidifier helps with humidity and damp

🤔 Who Should Buy the Devola 4-in-1?
Renters who can’t install split-unit ACs

Final Verdict: Cool, Convenient, and Competitively Priced
The Devola 9000 BTU 4-in-1 Portable AC might just be the best-value smart air conditioner available in the UK right now. It’s not just about cooling — it’s about comfort, control, and convenience.
If you're looking for an affordable, easy-to-use portable air conditioning solution with modern features like WiFi control and multiple operating modes, this unit is an excellent choice for summer 2025.
