10 Best Portable Room Coolers 2025 in the United States

The BLACK+DECKER Smart Portable Air Conditioner with Heat offers a versatile solution for room cooling and heating. With a cooling capacity of 14,000 BTU (ASHRAE) and 10,000 BTU (DOE), it is suitable for rooms up to 700 sq. ft., making it a good fit for medium to large spaces. The added 12,000 BTU heating capability further enhances its utility throughout the year, allowing for both summer cooling and winter heating. This unit also includes a dehumidifier and fan function, which adds to its versatility.

The water tank capacity and power consumption specifics are not detailed, but it does come with a 1-year warranty for reassurance on its durability. With a noise level of 54 dB, it operates relatively quietly, ensuring minimal disturbance. Portability is a strong suit with its compact dimensions (16.5” x 14.06” x 27.09”) and the inclusion of an installation kit for easy setup. Weighing 35 pounds, it is moderately easy to move around as needed.

Additional features such as Wi-Fi connectivity, voice control via Amazon Alexa or Google Assistant, and a 'Follow Me' remote provide advanced control options and convenience. However, it is not Energy Star rated and has a SEER of 6.2, which indicates it may not be the most energy-efficient option on the market. This portable air conditioner is ideal for users seeking a multi-functional, smart, and portable cooling and heating solution for medium to large rooms.

The BLACK+DECKER 12,000 BTU Portable Air Conditioner is designed to cool rooms up to 550 sq. ft., making it suitable for medium to larger spaces. Its 3-in-1 functionality as an air conditioner, dehumidifier, and fan adds versatility and convenience. The 'Follow Me' remote control feature allows for more precise temperature control, improving comfort.

The unit also includes a window installation kit for easier setup and Auto Water Evaporation to reduce maintenance effort, which are great additional features. With a noise level of 52 dB, it runs relatively quietly, making it suitable for bedroom use. The portability is enhanced by its wheels and side handles, facilitating easy movement between rooms. However, at 56.8 pounds, it might be a bit heavy for some users to handle.

The 0.8-liter water tank capacity is quite small, so you may need to empty it frequently when using the dehumidifier function, especially in very humid conditions. Power consumption is on the higher side with a SEER of 5.8, which might not be the most energy-efficient option available. If you're looking for a versatile and portable cooling solution for a larger room, this BLACK+DECKER model could be a reliable choice, but keep in mind the potential for frequent water tank emptying and higher power usage.

The SereneLife Small Air Conditioner is a solid choice for cooling small rooms up to about 300 square feet. Its 8,000 BTU cooling power suits compact spaces, using 1150 watts in cooling mode, which is typical for this size. A built-in dehumidifier removes around 1.1 liters of moisture per hour, making it effective for reducing humidity as well as cooling the air. Noise levels are low at about 55 dBa, ensuring quiet operation suitable for bedrooms or offices.

Mobility is enhanced with rolling wheels and a window mount kit for easy setup, ideal for moving the unit between rooms. It also offers WiFi connectivity and comes with a remote control, allowing convenient adjustments of temperature, fan speed, and timer settings from anywhere in the room. The water tank capacity is not separately specified because moisture is drained continuously, so drainage management depends on placement. While the 8,000 BTU rating works well for small rooms, it may be less effective in larger spaces or very hot conditions.

Weighing 45 pounds, the unit is manageable but might be heavy if frequently carried instead of rolled. This model combines effective cooling with features like dehumidifying and air purification, making it well-suited for users seeking a compact, feature-rich portable air conditioner primarily for small rooms.
