10 Best Small Portable Air Conditioners 2025 in the United States

The BLACK+DECKER 10,000 BTU Portable Air Conditioner is a solid choice for cooling rooms up to about 450 square feet. Its cooling capacity is suitable for small to medium rooms, making it practical for bedrooms or home offices. The unit combines three functions—air conditioning, dehumidifying, and fan modes—which adds versatility to help improve comfort beyond just cooling. It has an energy efficiency rating (SEER) of 6.7, which is decent and supported by a 5-star Energy Star certification, indicating that it won’t be a big energy drain. Noise-wise, it operates at 52 decibels, which is moderately quiet but may still be noticeable in very quiet environments like bedrooms at night.

On the portability front, it’s fairly lightweight at 47 pounds and includes casters and side handles, so moving it between rooms is straightforward. Controls are user-friendly with a top-mounted panel plus a remote control, adding convenience especially when you’re relaxing. Maintenance is manageable thanks to a slide-out washable filter and an auto water evaporation system that reduces the hassle of emptying water tanks regularly.

One minor downside is that the actual cooling power measured as SACC BTU is 5,800, which is somewhat lower than the rated 10,000 BTU, so it might struggle slightly in very hot or large rooms. Also, while the included window installation kit makes setup easier, window compatibility can vary depending on your space. This BLACK+DECKER model suits users looking for a portable, multifunctional air conditioner that’s easy to move and maintain, delivering effective cooling and dehumidifying for small to medium rooms without complicated controls.

The BLACK+DECKER Smart Portable Air Conditioner is a versatile unit suitable for rooms up to 700 sq. ft., making it a great choice for medium-sized spaces. With a cooling capacity of 14,000 BTU ASHRAE (10,000 BTU DOE), it offers robust cooling, which is essential during hot summer months.

Its energy efficiency ratio (SEER) of 6.2 is reasonable, though not the highest, indicating moderate efficiency in power usage. The noise level of 54 dB is relatively quiet for a portable unit, making it suitable for bedrooms or living areas where low noise is important.

Portability is a strong point, with dimensions of 16.5” x 14.06” x 27.09” and a weight of 62.4 pounds, which is manageable for most users.

The BLACK+DECKER Smart Portable Air Conditioner is designed for rooms up to about 550 square feet, making it suitable for medium-sized bedrooms or living areas. With a cooling capacity of 12,000 BTU (8,000 BTU SACC), it offers solid cooling power to handle warm days effectively. It also doubles as a dehumidifier and fan, which adds to its versatility during humid or milder weather. The energy efficiency ratio (SEER) of 5.8 is average and the unit is not Energy Star certified, so it might use more electricity compared to more efficient models. Noise-wise, it runs at 52 dB, which is moderate—noticeable but not overly disruptive, suitable for most home environments including bedrooms.

One standout feature is its smart connectivity, allowing control through a mobile app and voice commands via Alexa or Google Assistant, plus a remote with a “Follow Me” thermostat that helps maintain precise temperatures based on where the remote is located. Portability is decent given its size and weight (about 57 pounds), and it includes a window installation kit for easy setup, which is handy if you move it between rooms. Maintenance is relatively straightforward with auto water evaporation, which reduces the need to drain water manually often.

The unit is somewhat bulky compared to smaller portable ACs and lacks energy-saving certifications. Its warranty is limited to one year, which is fairly standard but might be short if you expect heavy use. This BLACK+DECKER model is a convenient, easy-to-control portable AC with good cooling for medium rooms, best suited for users valuing smart features and ease of installation, though it may not be the most energy-efficient or quietest option available.
