10 Best Portable Air Conditioner 2025 in the UK

The Pro Breeze® 12000 BTU Portable Air Conditioner is a powerful and versatile cooling solution, ideal for medium to large rooms, such as bedrooms and home offices. With a cooling capacity of 12000 BTU, it can efficiently lower temperatures to as low as 16°C. An impressive feature of this unit is its integration with smart home technology, allowing you to control the air conditioner via a mobile app or voice commands through Amazon Alexa and Google Home, offering great convenience.

The energy efficiency rating of Class A ensures that it operates cost-effectively, which is a significant advantage for those looking to save on electricity bills. It also uses the eco-friendly R290 refrigerant, which is kinder to the environment compared to traditional refrigerants. The unit is relatively quiet with a noise level of 54 dB, making it suitable for use in bedrooms or nurseries, especially in its sleep mode where it operates at a lower noise level.

Some users might find the size and weight (27.3 kg) a bit cumbersome when moving it around the house, despite the inclusion of wheels for portability. The package includes a window venting kit for easy installation, and the air conditioner also functions as a fan and dehumidifier, adding to its versatility. The LED display, remote control, and the ability to set timers further enhance its user-friendliness. The Pro Breeze® 12000 BTU Portable Air Conditioner is a highly efficient and feature-rich appliance, well-suited for users looking for a multi-functional and smart cooling solution for their homes or offices.

The Pro Breeze 4-in-1 Portable Air Conditioner offers solid cooling power with 9000 BTU, making it suitable for medium to large rooms like living rooms, bedrooms, or offices. It can cool spaces down to 16°C effectively. This model is energy efficient, carrying a Class A rating and using an eco-friendly R290 refrigerant, which helps keep running costs and environmental impact lower than many alternatives. Noise-wise, it produces about 54 dB, which is moderate—noticeable but not overly disruptive for most users.

Portability is decent: it weighs 24.5 kg and includes wheels, allowing you to move it around within your home without too much effort. It also comes with window venting kits for both sliding and hinged windows, which helps with proper exhaust and prevents hot air from coming back in. One of the standout features is its smart home compatibility—via WiFi, you can control the unit using a smartphone app or voice commands through Alexa or Google Home, adding convenience.

The 4-in-1 functionality means it’s more than just a cooler; it can dehumidify, work as a fan, and has a sleep mode for quieter, gentler operation at night. While the size is reasonable for portability, it’s still somewhat bulky compared to smaller units, and at 24.5 kg, moving it up and down stairs could be challenging. The noise level, though acceptable, may be noticeable in very quiet rooms or for light sleepers. The energy efficiency ratio (SEER 2.6) is decent but not the highest available, so if you want the best energy savings, there are more efficient units out there. This air conditioner is well suited for those needing flexible cooling with smart controls and energy-conscious operation in medium-sized spaces, especially users who appreciate tech features and easy installation but can handle a slightly heavier unit.

The BLACK+DECKER BXAC40008GB Portable 3-in-1 Air Conditioner is a versatile appliance, offering cooling, dehumidifying, and fan functionalities, making it suitable for rooms up to 24m2. Its 12,000 BTU cooling capacity ensures effective temperature control, particularly during hot seasons. This model stands out due to its Class A energy efficiency rating, which keeps running costs low while minimizing environmental impact. Additionally, the 24-hour timer and remote control enhance convenience, enabling easy operation from a distance.

One of the notable features is its dehumidifying capability, capable of extracting up to 40 litres of moisture per day, which can help combat dampness and mold in your home. A self-evaporating system manages water disposal, reducing the need for frequent manual emptying. The noise level at 65 dB, although higher than some quieter models, is manageable and won’t be too disruptive, particularly with its lower noise setting for nighttime use.

The unit's portability is somewhat limited by its weight of 26.7 kg, which could make it challenging to move frequently, despite its compact dimensions (39 x 35 x 85.5 cm). The ventilation and exhaust setup will require proper placement near a suitable window or outlet to function effectively. This BLACK+DECKER model is an efficient option for those looking to manage indoor climate in medium-sized rooms. Its solid cooling and dehumidifying performance are its main strengths, but potential buyers should consider its weight and noise level in relation to their specific needs.
