10 Best Energy Star Portable Air Conditioner 2026 in the United States

The Whynter Inverter Portable Air Conditioner offers a robust 14,000 BTU of cooling power, making it suitable for cooling spaces up to 600 square feet effectively. Its inverter technology stands out by providing 20% more efficient cooling, which can be beneficial for energy savings. The dual-hose design is particularly efficient in preventing heat leakage, further enhancing its cooling performance.

The unit also doubles as a powerful dehumidifier, capable of removing up to 87 pints of moisture per day, which is great for humid climates. This model offers smart control through the NetHome Plus app, allowing you to adjust settings via WiFi, and is compatible with voice assistants like Alexa and Google Home, adding to its convenience. User-friendliness is boosted by its washable air filter, which simplifies maintenance, and the inclusion of a programmable timer and remote control for ease of use.

The unit operates quietly at a noise level of 42.5 dB, which is relatively quiet for its class. The product dimensions are 16.75 inches deep, 19.5 inches wide, and 32.5 inches high, so ensure you have adequate space for it. The Whynter Inverter Portable Air Conditioner is a powerful and versatile unit with smart features and efficient cooling capabilities, making it a strong choice for larger rooms.

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.

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.
