10 Best Portable Air Conditioner

The De'Longhi Pinguino PACN82 Eco is a portable air conditioner designed for small to medium rooms (around 80 cubic meters) with a cooling capacity of 9,400 BTU (2.4 kW). It offers decent cooling power suitable for bedrooms or offices. Its energy efficiency is rated class A with a Seasonal Energy Efficiency Ratio (SEER) of 2.4, which means it uses electricity fairly economically compared to many portable ACs. One notable feature is the use of environmentally friendly propane gas (R290) which has no greenhouse emissions, adding an eco-conscious benefit.

The unit operates at a noise level of 52 dB, which is moderate—not too loud for most indoor settings but could be noticeable in very quiet rooms. The size and weight (30 kg) make it less easy to move around frequently; while it’s portable, it’s on the bulkier side compared to lighter models. Ventilation is handled via an exhaust hose, typical for portable ACs, which requires a window or outlet for hot air release.

Additional features include a dehumidifier function, three fan speeds to balance cooling power and noise, an electronic timer and thermostat for better control, and a remote control for convenience. These features add to user comfort and flexibility. Despite a relatively low star rating (1 Star BEE) and moderate customer reviews (4.2/5), the unit performs well for energy use and cooling. It is best suited for those who prioritize eco-friendliness and steady cooling in smaller spaces, though those needing a very quiet or highly portable unit might want to consider alternatives.

This NELGOLLE portable air conditioner offers 7000 BTU cooling capacity, suitable for rooms up to about 25 square meters, which makes it a decent choice for small to medium-sized spaces. Its energy efficiency rating of A means it should use power reasonably well, helping keep electricity costs manageable. The unit is fairly compact and comes with wheels and a handle, making it easy to move between rooms as needed, which is great if you want flexibility. Installation is straightforward thanks to the included window kit and exhaust hose, fitting most window types without much hassle.

The 4-in-1 functionality allows you to cool, ventilate, dehumidify, or run a quiet 'silent mode' for nighttime, adding versatility beyond basic cooling. The digital display and remote control provide easy operation and temperature monitoring. On the downside, while the unit aims for quiet operation, portable air conditioners naturally produce some noise due to the exhaust fan. At 23.9 kg, it’s portable but not lightweight, so moving it might require some effort. Also, the cooling power is modest, so it may struggle in very hot or larger rooms.

Maintenance is easy with a washable filter, but regular cleaning is necessary to keep performance optimal. This air conditioner suits users who want a flexible, energy-efficient cooling option for small to medium rooms, with simple setup and useful extra modes. It may not be the best fit if you need quiet operation at high cooling levels or for larger areas.

The Ariston MOBIS PLUS 10 UK is a solid choice if you need a portable air conditioner for a medium-sized room between 13 to 20 square meters. With a 10,000 BTU cooling capacity, it can effectively cool spaces of this size without struggling. One of its strong points is energy efficiency—rated A+ with an Energy Efficiency Ratio (EER) of 3.1, it should help keep electricity bills on the lower side compared to less efficient models. The noise level is reasonably quiet at 50 dB, which is about the sound of a moderate conversation, so it won’t be too distracting in your living room or bedroom.

Its size (roughly 40 x 47 x 77 cm) and design make it portable, but it is on the heavier side at nearly 32 kg, so moving it around might require some effort. Installation is straightforward in UK-style windows, as it comes with all necessary adapters and hoses. Additionally, the intuitive controls and remote make adjusting the temperature hassle-free.

While it carries a modest 1-star BEE rating, the A+ class and EER rating indicate good practical energy efficiency. Its cooling capacity is best suited for smaller rooms, so it may not perform well in larger or open-plan spaces. This model offers reliable cooling with good energy efficiency and quiet operation, making it a practical option for users wanting an easy-to-use, portable air conditioner for typical UK rooms.
