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 Whynter Portable Air Conditioner offers strong cooling power with 14,000 BTU, suitable for rooms up to 500 square feet, which makes it a good fit for medium to large bedrooms or living spaces. Its dual-hose design helps improve efficiency by using separate hoses for intake and exhaust, allowing quicker and more effective cooling compared to single-hose models. The unit runs relatively quietly at 51 decibels, making it suitable for bedrooms or home offices where low noise is preferred. It also includes a built-in dehumidifier that can remove up to 71 pints of moisture per day, which is great for humid climates. The energy efficiency ratio (EER) of 7.69 is decent, meaning it balances power use and cooling effect reasonably well, though it’s not the most energy-saving option available. The size (about 19 x 16 x 35.5 inches) and weight (73 pounds) make it less portable than smaller models; moving it around frequently might be challenging. Installation requires a window for venting, provided with a flexible kit, so it works best where window venting is possible.

Additional features like an activated carbon filter help improve air quality, and the unit offers three modes (cool, dehumidify, fan) with full thermostat control for convenience. One downside is its power consumption at 1300 watts, which might impact electricity bills if used extensively. Although it is award-winning and highly rated, the relatively large size and weight may not suit users looking for a very compact or lightweight portable AC. This Whynter model represents a solid choice if you want efficient, quiet cooling with dehumidifying for medium-large rooms and don’t mind the heavier size and window vent setup.
