4-in-1 Portable Air Conditioner 7000 BTU Review UK 2026
Quick verdict
Score: 7.8/10
Best for: Moveable cooling in a heatwave without fitting a fixed unit
Not for: Anyone wanting silent running or the lowest possible electricity use - a fan is cheaper but doesn't truly cool
Bottom line: A practical portable air conditioner (7000 BTU, 4-in-1) for proper, portable cooling around the home.
This review is based on the Other, built for rooms up to 15 m², with cooling, fan and dehumidifying modes. The key advantage is that the same unit combines multiple comfort functions for small spaces, with control via remote control and a 24-hour timer. The UK version also supports Wi-Fi/app access for routine management, but performance may not suit larger rooms, and window venting is required.

Cooling Power (BTU)
The 4-in-1 Portable Air Conditioner's cooling power is rated at 7000 BTU, and this rating is the main indicator of how much heat it can remove in use. The unit must work to maintain a steady temperature, so real-world cooling performance can vary. With a built-in fan and dehumidify mode, the cooling workload can change, particularly when indoor humidity is high. The 7000 BTU rating is suited to moderate comfort, but it may feel limited in hotter conditions. This is a portable option rather than a whole-home system.
Room Size and Coverage
With a stated capacity of cooling up to 15 m², the Other is designed for small, single-room spaces such as a bedroom, home office, or a compact living area. Coverage can vary with room layout, insulation, and sunlight exposure, so cooling may be more effective on cooler days. For best results, it needs proper placement with airflow and correct window venting set up, so warm air is expelled outside via the window venting kit. Larger open-plan rooms are less likely to feel uniformly cooled, because the unit is intended for limited areas.
Modes and Dehumidifier Function
After considering that this unit is intended for small spaces up to 15 m², it is useful to look at how its 4-in-1 operation supports day-to-day comfort, as results depend on the active mode. In cooling mode, the device lowers room temperature for comfort in warm conditions. Fan mode circulates air without aiming to reduce the temperature. The dehumidifier function reduces dampness, which can help rooms feel less sticky when humidity is high. Users can switch modes with the remote and use timers to start the selected mode, although performance will depend on the room conditions.
Noise Level and Energy Use
Noise level and energy use matter because this 4-in-1 portable air conditioner is designed for small rooms up to 15 m² and offers remote control, plus Wi-Fi and app control. Noise is most noticeable at higher fan speeds, and it can interfere with sleep or video calls. The unit is rated energy class A, which generally indicates lower running costs than less efficient models. The dehumidify and fan functions can reduce humidity while the unit is running, and continuous operation changes comfort because cooling depends on airflow.
Installation, Hose and Setup
Installation for this 4-in-1 portable air conditioner is designed to be fairly straightforward, but it still requires attention to window fit and hose routing. First, position the window venting kit, then attach the exhaust hose so the connection remains sealed when the unit is moved. The kit should match the window opening, because gaps can reduce cooling efficiency. Next, lay the hose with a gentle bend, avoiding sharp kinks or tight loops near doors. After placement, power on the unit, select cool, and check airflow from the outlet vents. Setup is then ready for normal use.
Who Is This Portable Air Conditioner For?
This portable air conditioner is best suited to people who need a mobile cooling setup for smaller rooms. It is rated at 7000 BTU and is intended for spaces up to 15 m², making it a practical option for renters or home users who prefer not to install a fixed unit, since it uses a venting kit for window exhaust (setup details follow). The 4-in-1 functions, including cooling, fan, and dehumidify, suit buyers who want one device for mixed day-to-day needs. Smart Wi-Fi and app control add convenience, while the remote control also helps with day-to-day operation.
Where to Buy in the UK
Where to buy this Other Smart Wifi in the UK depends on where shoppers can find the exact model with the features stated in the title, including smart Wi-Fi/app control, a remote control, a 24 hour timer, and the included window venting kit. Start with major UK retailers such as Amazon UK, John Lewis, Currys, AO, Argos, and B&Q, then check each listing for those same points.

Frequently Asked Questions
Is the Other worth it?
For cooling a room in a heatwave without fitting a fixed unit, the Other (7000 BTU) gives you proper, moveable cooling that a fan can't. Check the current Amazon UK price, as these spike in summer.
How much cooling power does the Other have?
The Other is rated at 7000 BTU. As a rough guide, around 5,000-7,000 BTU suits a small bedroom, 8,000-10,000 BTU a living room, and 12,000+ BTU larger or open-plan spaces - this one covers up to 15 m².
How many BTU do I actually need?
Match BTU to room size: roughly 5,000-7,000 BTU for a small bedroom, 8,000-10,000 for an average living room, and 12,000+ for large or sunny rooms. Too few BTU won't cool the space; too many wastes money and can leave it clammy.
Does the Other need a window or exhaust hose?
Yes - like all portable air conditioners, the Other vents hot air out through an exhaust hose, which needs to reach a window (a window-sealing kit is usually included). This is normal and the key difference from an air cooler, which doesn't cool as effectively.
Can the Other do more than just cool?
Yes - the Other is a 4-in-1 (cool, fan, dehumidify) that also works as a fan, so it earns its space year-round, not just in summer.
Are portable air conditioners expensive to run?
They use more electricity than a fan, since they have a compressor like a fridge. The Other is energy class A, which helps. Running cost depends on the wattage, how long you run it and your tariff - use it to cool a room then switch to a lower fan mode to keep costs down.
Where is the Other best used?
The Other suits any room where you want moveable cooling without a permanent installation - bedrooms, home offices and living rooms. You can wheel it between rooms, as long as each has a window for the exhaust hose.
