The BLACK+DECKER Smart Portable Air Conditioner with Heat is a versatile choice for rooms up to 700 sq. ft. It stands out with its 14,000 BTU (ASHRAE) cooling capacity and 10,000 BTU (DOE), ensuring it can handle larger spaces effectively. With an additional 12,000 BTU heating function, it is a reliable option all year round.

Despite not being Energy Star rated, it offers a Seasonal Energy Efficiency Ratio (SEER) of 6.2, which is decent but might not be the most energy-efficient option available. The noise level at 54 dB is relatively quiet, making it suitable for bedrooms and living areas without causing much disturbance. Portability is a key feature, with dimensions of 16.5” x 14.06” x 27.09” and a weight of 35 pounds, making it easy to move around.

The included remote control with FOLLOW ME function and smart features, such as Wi-Fi connectivity and voice control via Amazon Alexa or Google Assistant, add convenience and modern touches. The dehumidification function and the programmable timer and thermostat are useful for maintaining a comfortable environment. However, it could require regular maintenance, particularly regarding the filter. The installation kit is comprehensive, simplifying the setup process. It is a well-rounded portable air conditioner with additional heating capabilities, though those who prioritize energy efficiency might need to consider other options.

The BLACK+DECKER Portable Air Conditioner, with its 12,000 BTU (ASHRAE) cooling capacity, is efficient for rooms up to 550 sq. ft., making it suitable for medium-sized spaces like bedrooms and living rooms.

The 'Follow Me' remote control feature is a standout, enabling precise temperature control by acting as a thermostat. This is complemented by the easy-to-read LED display for convenient operation.

Mobility is another strong point, with built-in casters and side handles making it easy to move from room to room. The included window kit simplifies installation, so you can get it up and running without much fuss. However, this model has a few drawbacks. The energy efficiency ratio (EER) of 5.8 is relatively low, meaning it may consume more electricity compared to more energy-efficient models. Noise level at 52 dB, while not overly loud, could be noticeable in quieter settings.

Maintenance is straightforward with an auto water evaporation feature, though the filter will require periodic cleaning. This portable air conditioner is highly user-friendly and well-suited for those needing a reliable cooling solution with added dehumidification and fan options. It excels in ease of use and portability but may not be the most energy-efficient choice for those concerned about electricity consumption.

Portability is another strong point, with casters and side handles making it easy to move between rooms. The installation kit simplifies setup, which is a plus for users who prefer hassle-free installation processes.

Maintenance is straightforward, though, with a washable filter that keeps upkeep costs low. This BLACK+DECKER portable air conditioner is ideal for those seeking a multi-functional, easy-to-move cooling solution for small to medium-sized rooms, with the trade-off being its lower energy efficiency and moderate noise level.
