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 Honeywell 500 CFM Portable Evaporative Cooler is a solid choice if you live in a hot, dry climate and need a portable way to cool small to medium indoor or outdoor spaces up to about 300 square feet. Its 500 cubic feet per minute airflow provides noticeable cooling by using water evaporation, which also adds some humidity—helpful in dry areas or even during winter months. The large 6.6-gallon water tank means longer run times without frequent refills. It runs on 235 watts, which is quite energy-efficient compared to traditional air conditioners.

Noise level is around 64 dB, making it a bit louder than a quiet fan but still reasonable for most home or patio use. Portability is made easy with built-in wheels and a freestanding design, allowing simple movement between rooms or outside. Additional features like a remote control, low water alarm, timer, washable filter, and an ice compartment add convenience and versatility.

This unit cools through evaporation, so it works best when humidity is below 60% and won’t be as effective in very humid or large spaces. Also, the noise might be noticeable in very quiet environments. For those seeking an eco-friendly, low-power cooler for spot cooling in dry climates, this product is a suitable option. For stronger cooling needs in humid or larger areas, other options might be more appropriate.
