10 Best Portable Air Conditioners 2026 in the United States

The BLACK+DECKER Smart Portable Air Conditioner is a versatile unit with a solid cooling capacity of 14,000 BTU, making it suitable for rooms up to 700 square feet. It also doubles as a heater (up to 10,000 BTU), which is handy for year-round use. The device includes a dehumidifier and fan, adding to its functionality beyond just cooling. Its noise level is about 54 dB, which is moderate and might be noticeable but not overly disruptive in most home settings. The unit is somewhat large and weighs around 60 pounds, so while it's portable, it might not be the easiest to move frequently without some effort. It comes with an installation kit for window venting, simplifying setup.

Energy efficiency is average (SEER 6.2), and this model isn’t Energy Star certified, so it may use more power compared to more efficient options. The smart features, including Wi-Fi connectivity and voice control with Alexa or Google Assistant, add convenience, and the Follow Me remote is a neat feature that helps maintain precise temperature by using the remote as a thermostat. Programmable timer and full remote control improve user-friendliness. However, the water capacity for dehumidification is limited (0.8 liters), meaning you might need to empty it relatively often in very humid conditions. The lack of Energy Star rating and moderate noise level might be drawbacks for users prioritizing low energy consumption and quieter operation.

With a one-year warranty and positive customer ratings, this product represents a dependable choice for those needing a multi-function portable AC that covers both cooling and heating, suitable for medium to large rooms.

The BLACK+DECKER Smart Portable Air Conditioner is designed to cool rooms up to 700 square feet, making it a good choice for medium to large rooms like bedrooms or small living areas. It offers a strong cooling power of 14,000 BTU (10,200 BTU SACC), which should be effective in warm conditions. Besides cooling, it doubles as a dehumidifier and fan, adding to its versatility. The unit includes a washable filter and uses a more environmentally friendly refrigerant (R-32).

This model is moderately energy efficient with a SEER rating of 6.2, helping to keep electricity costs reasonable. Noise level sits around 54 decibels, which is somewhat noticeable but generally acceptable for a portable AC, especially in larger spaces. Portability is decent given its size (about 17 x 28 x 14 inches) and weight (62 lbs), so moving it around is possible but might require some effort.

A standout feature is its smart connectivity: you can control the AC with a mobile app or voice commands via Alexa or Google Assistant. The included remote has a 'Follow Me' function that uses the remote as a thermostat, allowing more precise temperature control wherever you are in the room. Installation is straightforward with the included window kit and exhaust hose. While the actual cooling capacity (SACC) is lower than the maximum BTU, which means it might perform less efficiently in very hot climates or poorly insulated rooms, it is quiet enough for most uses though noise might be noticeable in very quiet environments like bedrooms during sleep. The 1-year warranty offers basic coverage but might be limited for some users. This portable AC suits those who want a smart, multi-functional unit that can handle sizable rooms and appreciate easy control options, balancing good cooling power, useful features, and reasonable energy use, but may be less suited for very small spaces or users sensitive to noise.

The BLACK+DECKER Portable Air Conditioner offers a cooling capacity of 10,000 BTU ASHRAE (6,300 BTU DOE), making it suitable for rooms up to 450 sq. ft. This ensures effective cooling for medium-sized spaces. The unit is designed to be portable, featuring casters and side handles for easy mobility, which is a significant advantage if you need to move it between rooms.

The 'Follow Me' remote control is a convenient feature that allows for precise temperature control by acting as a thermostat, enhancing user comfort. Additionally, the unit functions as a dehumidifier and fan, providing extra versatility and comfort during humid conditions. The included window kit simplifies installation, making it user-friendly even for those with limited technical skills.

The noise level at 52 dB is relatively moderate, which might disturb light sleepers. The Energy Efficiency Ratio (EER) of 6.7 is on the lower side, indicating it may not be the most energy-efficient option, potentially leading to higher electricity bills. The size is fairly compact with dimensions of 15.3” x 14” x 24.8”, ensuring it won't take up too much space. This air conditioner is ideal for users seeking a portable and multifunctional cooling solution for medium-sized rooms, though it comes with some limitations in energy efficiency and noise level.
