10 Best Se Portable Ac Units 2026 in the United States

The BLACK+DECKER Smart Portable Air Conditioner offers a solid option for cooling rooms up to about 500 square feet with its 12,000 BTU capacity. While the seasonal energy efficiency ratio (SEER) of 5.8 is moderate and it is not Energy Star certified, it provides decent cooling power for the price. Noise level sits around 52 dB, which is fairly average—noticeable but not overly disruptive for most settings like bedrooms or home offices. Its size is typical for portable units, and though it weighs nearly 57 pounds, it remains movable with some effort. The included window installation kit simplifies setup, though proper ventilation remains necessary for optimal performance.

A standout feature is the smart functionality; it supports Wi-Fi control through a mobile app and voice commands via Alexa or Google Assistant, adding convenience uncommon in many portable ACs. The Follow Me remote is also a nice touch, using its location to adjust cooling precisely where you are. It doubles as a dehumidifier and fan, offering versatility through the warmer months. On the downside, the water tank capacity is small (0.8 liters), which could require frequent attention in very humid environments unless auto-evaporation works effectively.

Due to the lack of Energy Star rating, it might consume more electricity than more efficient models, so it's best suited for users who value smart features and ease of use over maximum energy savings. This unit is a good fit for homeowners or renters who want a reasonably powerful, easy-to-control portable AC with smart technology, though it might not be the best pick if low noise or top-tier efficiency is a priority.

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.

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.
