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 Uthfy 41" Swamp Cooler is a strong choice if you're looking for a portable air cooler that can refresh large spaces, up to about 1200 square feet. Its cooling power is impressive, delivering 4800 cubic feet per minute (CFM) of airflow, which means it can cool down areas like garages, patios, or yards effectively. The 10.6-gallon water tank is quite large, allowing the unit to run for many hours without needing a refill, and the option to connect a garden hose for automatic water filling adds convenience if you plan to use it frequently outdoors.

This cooler uses evaporative cooling with a 3-sided cooling pad and includes three ice packs to enhance the cooling effect, making it more energy-efficient compared to traditional portable air conditioners. It has three speed settings and 110° oscillation to spread cool air evenly. Noise levels are relatively low at about 45 dB, so it won't be too disruptive for casual use. Portability is well-thought-out here, with built-in 360° caster wheels—two with brakes—to move it easily around your space. The metal body with powder coating improves durability against outdoor elements and makes cleaning easier. Plus, the copper motor is designed for quiet, efficient operation and longer life.

Keep in mind that as an evaporative cooler, it works best in dry climates rather than humid ones. It requires regular water refills and maintenance of the cooling pads. At 44 pounds, it’s portable but not ultra-lightweight, so consider this if you'll be moving it often. The Uthfy 41" Swamp Cooler delivers powerful, energy-efficient cooling with useful features for outdoor or large indoor spaces, especially in dry conditions, but it needs water supply access and routine upkeep to perform well.

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.
