10 Best Energy Star Portable Air Conditioner 2025 in the United States

The BLACK+DECKER Smart Portable Air Conditioner offers strong cooling with 14,000 BTUs, suitable for rooms up to 700 square feet, making it a good choice for larger bedrooms or living areas. Its energy efficiency ratio (SEER) of 6.2 is decent, helping to manage electricity consumption without being the most efficient on the market. The noise level at 54 decibels is moderate—quiet enough for most living spaces but might be noticeable in very quiet rooms.

Portability is practical with its size and included window installation kit, though it weighs about 62 pounds, so moving it around may require some effort. A notable feature is its smart functionality, allowing control via an app or voice commands through Alexa and Google Assistant, plus the “Follow Me” remote that measures temperature wherever the remote is placed, enhancing comfort control. Besides cooling, it works as a dehumidifier and fan, which adds versatility during warmer months. The washable filter is easy to maintain, reducing ongoing costs.

On the downside, while it’s not overly complicated to set up, the unit’s size and weight may limit portability for some users. Also, the energy efficiency is average rather than top-tier, so power bills could be higher with frequent use. This BLACK+DECKER portable AC is well-suited for users who want a powerful, smart-controlled cooling unit for larger rooms with added dehumidifying capabilities, while accepting some trade-offs in noise and portability.

The BLACK+DECKER Portable Air Conditioner offers a cooling capacity of 12,000 BTU (ASHRAE) and 8,000 BTU (DOE), making it suitable for rooms up to 550 sq. ft. This unit stands out with its three-in-one functionality, acting not only as an air conditioner but also as a dehumidifier and fan. The 'Follow Me' remote control is a nice touch, allowing for more precise temperature control by acting as a thermostat. The unit is designed for easy mobility with built-in casters and side handles, making it simple to move from room to room.

The installation kit included makes setup straightforward, and the auto water evaporation feature reduces maintenance needs. However, the SEER rating of 5.8 indicates it might not be as energy-efficient as some other models. At 52 dB, the noise level is moderate but could be a concern if you're very sensitive to sound. The air conditioner includes environmentally friendly R410a refrigerant, adding a green touch. It's relatively heavy at 56.8 pounds, which might make it less convenient to move frequently.

The user-friendly LED display and top-mounted control panel, along with a programmable timer, add to its ease of use. This portable air conditioner is well-suited for those looking for versatility and ease of movement in cooling solutions, though it might not be the best choice for those prioritizing energy efficiency or noise control.

The BLACK+DECKER Portable Air Conditioner boasts a cooling capacity of 9,000 BTU (ASHRAE) or 5,300 BTU (DOE), making it suitable for rooms up to 400 sq. ft. It also functions as a dehumidifier and fan, adding versatility. The unit's Energy Efficiency Ratio (EER) is relatively low at 5.4, which means it may not be the most energy-efficient option available.

Its portability is a strong point, with casters and side handles making it easy to move between rooms. The noise level is 54 dB, which is moderate and may be noticeable but not overly disruptive. The 'Follow Me' remote control is a convenient feature that allows for precise temperature control by acting as a thermostat. Additionally, the easy-to-install window kit simplifies setup. Maintenance is straightforward with a reusable filter.

However, at 52.9 pounds, it is on the heavier side for a portable unit. This air conditioner is best suited for those looking for a versatile, portable solution for medium-sized rooms, who don't mind a bit of noise and are okay with a lower energy efficiency rating.
