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 Whynter Inverter Portable Air Conditioner is a robust option for cooling large spaces up to 600 square feet with a significant 14,000 BTU cooling capacity. It's designed for high efficiency, boasting a dual-hose system that cools 20% more effectively and uses 40% less energy. This makes it an excellent choice for those who want powerful cooling without astronomical energy bills. The built-in dehumidifier is a handy feature, capable of removing up to 87 pints of moisture per day, which is ideal for humid environments. Users can enjoy smart control options through the NetHome Plus app, which integrates with Alexa and Google Home for voice commands, adding convenience and modern functionality.

This model operates at a quiet 42.5 dB, making it suitable for quieter settings like bedrooms or offices. However, one drawback is its lack of an Energy Star rating, which might be a consideration for eco-conscious buyers. The unit's portability is facilitated by its wheels and a relatively compact design (16.75”D x 19.5”W x 32.5”H). The inclusion of a window installation kit and washable air filter adds to its usability and ease of maintenance.

On the downside, its power consumption is relatively high at a maximum of 1293W, and the product might be on the pricier side given its comprehensive features. In summary, the Whynter Inverter Portable Air Conditioner is well-suited for those needing efficient, powerful cooling and modern connectivity features, but it might not be the best choice for buyers focused on energy efficiency certifications.
