10 Best Se Portable Ac Units 2026 in the United States

The Dreo Portable Air Conditioner offers a solid cooling capacity of 8000 BTU (ASHRAE rating) but effectively 5000 BTU DOE, making it suitable for small to medium bedrooms up to about 150 square feet. Its energy efficiency is decent with a SEER of 6.1, which should keep running costs reasonable for this type of unit. One of the standout features is its very quiet operation at 45 dB, thanks to Dreo’s patented noise isolation system, making it a good choice for bedrooms or workspaces where low noise is important.

The unit is fairly portable with smooth caster wheels and fits a wide range of window sizes using modular panels, though at about 25 inches tall and weighing 55 pounds, it’s not the lightest model around. Installation includes an exhaust hose that needs window ventilation, which is typical but something to plan for. The drainage-free system is convenient since it automatically evaporates moisture, eliminating the hassle of manual drainage in most humid conditions.

Additional smart features include app and voice control compatibility (Siri, Alexa, Google Assistant), customizable temperature and humidity settings, and a sleep curve function that can enhance comfort during the night. The cooling power may be limited for larger rooms or very hot climates, and while the noise level is low, it’s not completely silent. Also, some users might find the 59-inch exhaust hose a bit short depending on their window setup. The Dreo AC318S is a versatile and user-friendly portable AC that fits well in small bedrooms or personal spaces where quiet operation and smart features are valued.

The BLACK+DECKER Smart Portable Air Conditioner offers a strong cooling capacity of 14,000 BTU, making it suitable for cooling rooms up to 700 square feet, which fits well for medium to large rooms. It also works as a dehumidifier and a fan, giving you versatile comfort options beyond just cooling. With a SEER (Seasonal Energy Efficiency Ratio) of 6.2, its energy efficiency is moderate, so it won't be the cheapest on your electricity bill but not overly costly either.

Noise is a consideration here; at 54 decibels, it's somewhat noticeable, roughly like a normal conversation, which could be a bit distracting for very quiet settings like bedrooms at night. The unit is fairly portable for its size and power, measuring about 16.5 x 14 x 27 inches and weighing 62.4 pounds—manageable if you need to move it between rooms but not super light. Installation is straightforward with the included window kit and exhaust hose, designed for typical window setups, though proper ventilation is necessary as with all portable ACs. A standout feature is its smart capabilities: you can control it via a mobile app or voice commands with Alexa and Google Assistant, plus the Follow Me remote acts like a thermostat, improving temperature accuracy where you are in the room. The washable filter is a plus for maintenance and longevity.

The cooling capacity stated as ASHRAE (14,000 BTU) versus the lower SACC rating (10,200 BTU) indicates real-world cooling might be less than the headline number suggests, which is common in portable units but worth knowing. Also, the 1-year warranty is somewhat short compared to some competitors. This BLACK+DECKER model is a solid choice if you want a smart, multi-purpose portable AC for medium-large rooms and don't mind a bit of background noise or moderate energy use.

The BLACK+DECKER Portable Air Conditioner offers a cooling capacity of 9,000 BTU ASHRAE (5,300 BTU DOE), suitable for rooms up to 400 sq. ft. It's a versatile three-in-one unit functioning as an air conditioner, dehumidifier, and fan. The unit comes with a 'Follow Me' remote, allowing precise temperature control by acting as a thermostat.

Its easy mobility, facilitated by casters and side handles, makes it convenient to move between rooms. An included window kit aids straightforward installation, while the vented airflow outlet ensures efficient cooling. However, its Seasonal Energy Efficiency Ratio (SEER) is relatively low at 5.4, indicating it may not be the most energy-efficient option available.

At a noise level of 54 dB, it might be slightly noisy for some users, particularly in quiet environments like bedrooms. It weighs 52.9 pounds, which is manageable but might be heavy for some users to move frequently. It's a solid choice for those needing a portable cooling solution for medium-sized rooms, balancing functionality and ease of use.
