10 Best Portable Room Air Conditioners 2025 in the United States

The BLACK+DECKER 10,000 BTU portable air conditioner is designed for rooms up to 450 square feet, making it a good fit for apartments, dorms, or small living spaces. It combines cooling, dehumidifying, and fan functions, which gives you flexible control over your comfort. The unit has a moderate noise level of about 53 dB, so it won’t be completely silent but should be tolerable for most daytime use. It includes a full-function remote control and an easy-to-install window kit, boosting convenience and portability.

Its cooling power is solid for the size of room it targets, though the energy efficiency ratio (EER) of 2.6 is on the lower side compared to some other models, meaning it may use more electricity to run. The unit features an auto water evaporation system that reduces the need to manually drain water, simplifying maintenance. It also offers a programmable thermostat and timer, allowing you to set cooling schedules and maintain a comfortable temperature without constant adjustments.

However, the weight (around 55 pounds) means it isn’t the lightest option, so moving it frequently might require some effort. The plastic build is standard for portable units but may feel less durable than heavier-duty models. With a 1-year warranty and positive customer ratings, this BLACK+DECKER portable AC is a practical choice if you want straightforward, multi-function cooling for small to medium rooms, but if energy efficiency or very quiet operation is a priority, you might find better options elsewhere.

The BLACK+DECKER Portable Air Conditioner is a versatile unit with a cooling capacity of 10,000 BTU ASHRAE (6,300 BTU DOE), suitable for rooms up to 450 sq. ft. It combines air conditioning, dehumidification, and fan functions, making it a multifunctional appliance. The 'Follow Me' remote control feature is a strong point, allowing the remote to act as a thermostat for better temperature control, which can be very convenient for users seeking precise cooling without adjusting the unit manually.

With a noise level of 52 dB, it is relatively quiet, ensuring a peaceful environment, especially useful in bedrooms or offices. The unit's mobility is enhanced by casters and side handles, enabling easy transfer between rooms. Additionally, it comes with an easy-to-install window kit, simplifying the setup process.

However, the energy efficiency ratio (EER) of 6.7 indicates it is not the most energy-efficient model available, potentially leading to higher electricity consumption. While the dehumidification feature is beneficial, the capacity is modest at 0.45 liters, meaning it may require more frequent emptying in humid conditions. This BLACK+DECKER model stands out for its multifunctionality, ease of use, and mobility, though it may not be the best choice for those prioritizing energy efficiency.

The BLACK+DECKER Smart Portable Air Conditioner with Heat is a versatile choice for rooms up to 700 sq. ft. It stands out with its 14,000 BTU (ASHRAE) cooling capacity and 10,000 BTU (DOE), ensuring it can handle larger spaces effectively. With an additional 12,000 BTU heating function, it is a reliable option all year round.

Despite not being Energy Star rated, it offers a Seasonal Energy Efficiency Ratio (SEER) of 6.2, which is decent but might not be the most energy-efficient option available. The noise level at 54 dB is relatively quiet, making it suitable for bedrooms and living areas without causing much disturbance. Portability is a key feature, with dimensions of 16.5” x 14.06” x 27.09” and a weight of 35 pounds, making it easy to move around.

The included remote control with FOLLOW ME function and smart features, such as Wi-Fi connectivity and voice control via Amazon Alexa or Google Assistant, add convenience and modern touches. The dehumidification function and the programmable timer and thermostat are useful for maintaining a comfortable environment. However, it could require regular maintenance, particularly regarding the filter. The installation kit is comprehensive, simplifying the setup process. It is a well-rounded portable air conditioner with additional heating capabilities, though those who prioritize energy efficiency might need to consider other options.
