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 SereneLife Small Portable Air Conditioner offers solid cooling power with 10,000 BTU, making it suitable for rooms up to 450 square feet. It’s a good choice if you want a device that not only cools but also includes a built-in dehumidifier and fan modes, which help improve comfort on humid days. The unit features a decent energy efficiency ratio (SEER of 10.5), which means it balances performance and energy use fairly well. Noise-wise, it runs around 52 decibels, so it’s relatively quiet for a portable AC but still noticeable in very quiet environments. Portability is a plus here—though it’s on the heavier side at about 55 pounds, it has smooth wheels and side handles that make moving it between rooms manageable. The included 59-inch exhaust hose and window sealing kit simplify setup, important for proper ventilation.

The digital control panel and remote control add convenience, allowing easy adjustments of temperature, fan speed, and modes from across the room. While it provides strong cooling and dehumidifying functions, the unit’s size is a bit bulky compared to smaller models, and it requires a window for exhaust. The one-year warranty is standard but not extensive. For those needing a reliable portable AC with multiple functions for medium-sized rooms and who don’t mind a bit of weight, this model offers good value and ease of use.
