10 Best Portable Air Coolers 2025 in the United States

The BLACK+DECKER Smart Portable Air Conditioner with Heat is a versatile option for those looking to cool or heat a room up to 700 sq. ft. Its 14,000 BTU ASHRAE (10,000 BTU DOE) cooling capacity and 12,000 BTU heating capacity make it suitable for year-round use.

One of its standout features is its smart functionality, allowing control via a mobile app or voice commands through Amazon Alexa or Google Assistant. The 'Follow Me' remote control feature enhances convenience by enabling precise temperature control from any part of the room where the remote is located. Additionally, the unit includes a dehumidifier and fan, making it a four-in-one appliance that can adapt to various needs throughout the year.

The Seasonal Energy Efficiency Ratio (SEER) of 6.2 suggests it may not be the most energy-efficient option available. The noise level of 54 dB is relatively moderate but may still be noticeable in quieter environments. Portability is a strong point, given its compact dimensions (16.5” x 14.06” x 27.09”) and a weight of 35 pounds, making it easy to move from room to room. An installation kit is included, simplifying setup. However, it lacks Energy Star certification, which might be a concern for eco-conscious users. This portable air cooler is best suited for those who need a multi-functional unit that can provide cooling, heating, and dehumidifying capabilities with the added convenience of smart controls.

The BLACK+DECKER Portable Air Conditioner is a versatile and convenient cooling solution for rooms up to 550 square feet. It boasts an 8,150 BTU SACC/CEC rating and a higher 12,000 BTU ASHRAE rating, ensuring effective cooling for larger spaces such as apartments and cabins. One key strength is its three-in-one functionality, serving as an air conditioner, dehumidifier, and fan, which can cater to various comfort needs. The 'Follow Me' remote control feature is particularly useful, allowing precise temperature control by acting as a thermostat.

The unit is easy to install with a window kit and exhaust hose, making setup straightforward. With a noise level of 53 dB, it is relatively quiet for its size and power, promoting a comfortable environment without excessive noise. However, it does not have an Energy Star rating, which might be a consideration for those focused on energy efficiency. Additionally, while the product is portable with wheels, its weight of 55.4 pounds might make it less easy to move for some users.

The auto water evaporation feature reduces maintenance, negating the need for frequent water bucket draining. Despite these advantages, it’s not the most energy-efficient option available, as indicated by its SEER rating of 2.6. Users looking for a powerful and multi-functional cooling unit for larger spaces would benefit most from this product, especially if energy consumption is not their primary concern.

The Hessaire MC18M portable swamp cooler offers solid cooling power with its 1300 CFM airflow, suitable for outdoor or large indoor spaces up to 500 square feet. Its 4.8-gallon water tank is fairly generous, allowing a few hours of continuous cooling before needing a refill. It uses energy efficiently at 82 watts, which helps reduce electricity costs compared to traditional air conditioners. Noise is moderate at about 53 dB—comparable to a quiet conversation—which makes it fairly unobtrusive but might be noticeable in very quiet settings.

The cooler is designed for portability with wheels and a top handle, weighing 16 pounds, making it easier to move around despite its size. The body is made from lightweight ABS resin, which balances durability with lightness. The two-speed fan control and a patented axial propeller improve air throw distance, enhancing comfort in larger areas. As an evaporative cooler, it works best in dry climates and outdoors, as it adds moisture to the air rather than lowering temperature like a refrigeration-based air conditioner.

Maintenance is simple but requires regular water refilling and occasional drying before storage. For those living in hot, dry areas and needing an energy-friendly, portable cooler mainly for outdoor or well-ventilated spaces, the Hessaire MC18M serves as a practical choice. It may not perform well in humid environments or sealed indoor rooms.
