10 Best Portable Air Conditioner 2026 in the United States

The BLACK+DECKER Portable Air Conditioner offers a solid cooling capacity with 10,000 BTU ASHRAE (6,300 BTU DOE), suitable for rooms up to 450 sq. ft. This makes it a good choice for medium-sized rooms. It provides three functionalities in one unit: air conditioning, dehumidification, and fan-only mode, adding versatility to its use.

The 'Follow Me' remote control is a standout feature, allowing more precise temperature control by using the remote as a thermostat. This can enhance comfort by ensuring the temperature is optimal where you are, not just where the unit is located. Mobility is well-designed with casters and side handles, making it easy to move around your home. The included window installation kit simplifies setup, which is a bonus for users who prefer an easy installation process.

On the downside, the unit's SEER rating of 6.7 is relatively low, indicating it’s not the most energy-efficient option on the market. Additionally, with a noise level of 52 dB, it might be slightly noisy for light sleepers, though it is still within an acceptable range for most users. This portable air conditioner is a convenient and effective solution for cooling medium-sized rooms, though it may not be the quietest or most energy-efficient option available.

The BLACK+DECKER Portable Air Conditioner offers a solid solution for cooling rooms up to 550 sq. ft. with its 12,000 BTU ASHRAE rating (8,000 BTU DOE). One of its standout features is the 'Follow Me' remote control, which allows for more precise temperature control by acting as a thermostat. This can be particularly useful for ensuring even cooling throughout the room. Additionally, this unit is easy to move around thanks to its casters and side handles, making it convenient for use in different rooms.

The included window kit simplifies installation, and the unit also functions as a dehumidifier and fan, adding to its versatility. The environmentally friendly R410a refrigerant is another plus for those concerned about ecological impact. However, the SEER rating of 5.8 indicates that it is less energy efficient compared to some other models, which might result in higher electricity bills over time.

The noise level of 52 dB is moderate, meaning it shouldn’t be too disruptive, although it might be noticeable in very quiet environments. The unit's dimensions (13.8 x 17.1 x 28.1 inches) and weight (56.8 pounds) mean it is relatively compact but still substantial enough to ensure effective cooling. In summary, this BLACK+DECKER model is particularly well-suited for users looking for a portable and versatile cooling solution with easy mobility and additional dehumidifying and fan features, though those prioritizing energy efficiency might want to consider other options.

The Dreo Portable Air Conditioner offers effective cooling with its 8000 BTU (ASHRAE) capacity, suitable for rooms up to about 150 square feet. It uses an R-32 refrigerant and has a decent SEER of 6.1, indicating reasonable energy efficiency for this type of device. One of its standout features is the patented noise isolation system that keeps operation quiet at 45 dB, making it a good choice for bedrooms or offices where low noise is important. The unit also includes a true drainage-free system which automatically handles water evaporation, reducing maintenance hassle, especially in humid environments. Portability is well addressed with caster wheels and a relatively compact size (about 15 x 14 x 25 inches), though it weighs 55 pounds, which might be a bit heavy for some users to carry frequently.

Installation is flexible with modular window panels fitting various window types and a 59-inch exhaust hose, making setup manageable for most users. The smart climate control stands out by allowing voice commands through Alexa, Google Home, or Siri, plus an app to monitor temperature and humidity, adding convenience for tech-friendly users. The 3-in-1 cooling, fan, and dehumidifying modes add versatility for different weather conditions.

The cooling capacity, while adequate for small to medium rooms, might not be enough for larger spaces. Also, while energy efficiency is decent, this model isn’t the most efficient on the market, so electricity costs could be moderate with frequent use. This unit is well-suited for those needing a quiet, smart, and easy-to-use portable AC for bedrooms or small rooms, especially where drainage-free operation and remote control are valued.
