10 Best Lightweight Portable Air Conditioner 2025 in the United States

The BLACK+DECKER Smart Portable Air Conditioner, with its 14,000 BTU ASHRAE (10,000 BTU DOE) cooling capacity, is a strong choice for cooling rooms up to 700 square feet. Weighing 62.4 pounds, it is relatively easy to move around, although it might be a bit heavy for some users. This unit stands out with its smart features, including Wi-Fi connectivity and voice control compatibility with Amazon Alexa and Google Assistant, making it convenient to operate remotely.

The 'Follow Me' remote function allows for precise temperature control, which is a useful feature for maintaining comfort in specific areas of your room. Additionally, this air conditioner also functions as a dehumidifier and fan, offering versatility in different weather conditions. The energy efficiency ratio (SEER) is 6.2, which may not be the most efficient on the market but is reasonable given its power and multifunctionality. Noise levels are at 54 dB, which is relatively low and should not be too disruptive, especially if used in a bedroom. Installation is also made easy with the included window kit.

Some users might find the weight a bit cumbersome when moving it between rooms. Furthermore, the energy efficiency could be improved, considering other models have higher EER ratings. Despite this, the BLACK+DECKER Smart Portable Air Conditioner offers a solid balance of cooling power, smart features, and ease of use, making it a suitable option for those looking to cool medium to large rooms efficiently.

The BLACK+DECKER 8,000 BTU Portable Air Conditioner is a solid choice for cooling rooms up to 350 square feet, making it ideal for bedrooms and small living spaces. Weighing approximately 45.8 lbs, it is relatively easy to move around, thanks to its caster wheels and side handles. This unit also functions as a dehumidifier and fan, offering good versatility in a compact package.

The 'Follow Me' remote control feature is a nice touch, allowing for precise temperature adjustments based on the remote's location rather than the unit itself, which can improve comfort. The included installation kit facilitates an easy setup, so you can start cooling your space without much hassle. The cooling efficiency, with a Seasonal Energy Efficiency Ratio (SEER) of 5.4, might not be the most energy-efficient option on the market.

Additionally, while the noise level is rated at 54 dB, it might still be slightly loud for very noise-sensitive individuals when running at higher settings. In summary, if you need a portable and reasonably priced air conditioner that offers decent cooling and additional features like dehumidification and fan modes, this BLACK+DECKER model is a competent option, especially for smaller rooms.

The BLACK+DECKER 12,000 BTU Portable Air Conditioner is a strong contender in the lightweight-portable-air-conditioner category. With a cooling capacity of 12,000 BTU, it can effectively cool rooms up to 550 sq. ft., making it suitable for medium-sized spaces. The unit's weight is 56.8 pounds, which is relatively heavy for a portable model, but its design includes casters and side handles for easier mobility, helping mitigate this issue.

This air conditioner boasts a Seasonal Energy Efficiency Ratio (SEER) of 5.8, which is decent but not the most energy-efficient option available. The noise level is 52 dB, which is moderate and should allow for comfortable use without being overly disruptive. The 3-in-1 functionality (air conditioner, dehumidifier, and fan) is a notable strength, adding versatility to its use. The dehumidification function is an added benefit for maintaining comfortable humidity levels in the room.

Control options are user-friendly with a top-mounted LED display and a 'Follow Me' remote that acts as a thermostat for precise temperature control. This feature is particularly convenient for personalized comfort. The product comes with a complete installation kit, easing the setup process. Energy efficiency might be a drawback for those prioritizing lower energy consumption. In summary, this BLACK+DECKER model is a well-rounded option for users needing effective cooling and dehumidification in medium-sized spaces, with user-friendly controls and acceptable noise levels, though it might not be the lightest or most energy-efficient choice available.
