10 Best Portable Air Conditioner 2026 in the United States

The Hisense 8,000 BTU portable air conditioner is a solid choice for cooling spaces up to about 350 square feet, making it suitable for bedrooms or small living rooms. Its dual-hose design helps cool more efficiently and maintain consistent temperatures better than single-hose models. Thanks to inverter technology, it uses less energy—up to 40% more efficient—so it can help save on electricity bills. The noise level is fairly low at 42 decibels, which is about as quiet as a normal conversation, allowing you to use it comfortably in bedrooms or offices. It also offers three modes: cooling, dehumidifying, and fan-only, adding versatility for different weather conditions.

The unit comes with a remote and a window installation kit, making setup and daily use straightforward. On the downside, it weighs 65 pounds, which might be a bit heavy if you plan to move it often. While the size is compact enough to fit in most rooms, keep in mind it requires a window with specific dimensions for the exhaust hose. Also, it has a limited 90-day warranty, which is shorter than some competitors, so warranty support is limited.

Its smart features, including Wi-Fi connectivity and voice control via Google and Alexa, add convenience but may be more useful to those comfortable with smart home devices. This Hisense model successfully balances effective cooling and energy efficiency with quiet operation and handy smart features, although it may be somewhat bulky to move and has a shorter warranty period.

The BLACK+DECKER Smart Portable Air Conditioner is a solid choice for cooling rooms up to 700 sq. ft. With 14,000 BTU ASHRAE (10,000 BTU DOE), it offers substantial cooling power, making it suitable for larger spaces. Its portable design (16.5” x 14.06” x 27.09”) makes it easy to move around, though it's on the heavier side at 62.4 pounds. The SEER of 6.2 indicates decent energy efficiency, though not the best in its class. The noise level of 54 dB is relatively moderate, meaning it won't be too disruptive in most settings.

One of its standout features is the 'Follow Me' remote, which acts as a thermostat for more precise temperature control. Additionally, the smart capabilities, including Wi-Fi connectivity and voice control via Amazon Alexa or Google Assistant, provide modern, hands-free convenience. The included installation kit makes setup straightforward, though some users might find the included window kit a bit cumbersome.

The unit also functions as a dehumidifier and a fan, adding to its versatility. The washable filter is a practical feature for easy maintenance. However, some users might find the need for occasional manual water drainage due to its dehumidifying function an extra task. It’s an excellent option for those looking for a smart, multi-functional, and powerful portable air conditioner, though it may not be the quietest or most energy-efficient option available.

The BLACK+DECKER Portable Air Conditioner with 14,000 BTU cooling power is designed to cool rooms up to 700 square feet, making it suitable for medium to large bedrooms or living areas. It also includes a heating function (12,000 BTU) for year-round comfort, plus dehumidifier and fan modes, which adds versatility beyond standard cooling. The unit’s noise level is about 52 decibels, which is moderately quiet—similar to a conversation—so it should be comfortable for sleeping or working. With dimensions roughly 27 x 16.5 x 14 inches and weighing 35 pounds, it offers reasonable portability but might require some effort to move around frequently. Installation is fairly straightforward thanks to the included window kit and exhaust hose.

Energy efficiency is moderate with a Seasonal Energy Efficiency Ratio (SEER) of 6.2, and the unit uses an environmentally friendly refrigerant (R-32), but it isn’t Energy Star rated, meaning it may use more power than the most efficient models. One of its standout features is smart connectivity—it supports Wi-Fi control via a mobile app and voice commands through Alexa or Google Assistant, plus the remote control’s “Follow Me” function uses the remote’s location to maintain your desired temperature accurately. However, it does not have an inverter compressor, which means it might use more electricity and be less quiet during operation compared to inverter models. The washable filter is a plus for easy maintenance.

This BLACK+DECKER portable AC represents a solid option if you want a multi-functional unit with smart features for a medium-sized room, though it may not be the most energy-efficient choice available.
