Most important from
18 reviews
The BLACK+DECKER Smart Portable Air Conditioner offers strong cooling power with 12,000 BTU, making it suitable for larger rooms up to 550 square feet like apartments or spacious living areas. Its inverter compressor is a notable feature, helping to maintain consistent cooling while improving energy efficiency, reflected in its SEER rating of 11. This means it can help save on electricity compared to less efficient models. The unit also serves as a dehumidifier and fan, which adds versatility for managing room comfort beyond just cooling.
A helpful portability feature is the included window kit and wheels, simplifying installation and moving the AC between rooms or seasons. The smart Wi-Fi connectivity allows easy control from a smartphone, adding convenience. The noise level at 52 decibels is average—not very loud but noticeable in quiet rooms. It weighs 55 pounds, so while portable, it may require some effort to move. Maintenance involves managing the air filter and window exhaust setup, which is typical for portable ACs but something to keep in mind.
The programmable timer and thermostat help customize cooling schedules, enhancing comfort and saving energy. Taking these factors into account, this BLACK+DECKER model is a solid choice for those seeking an energy-efficient, multi-function portable AC for larger spaces, with manageable trade-offs in noise and weight.

Most important from
836 reviews
The Midea MAP14HS1TBL is a versatile 3-in-1 portable air conditioner that combines cooling, dehumidification, and fan functions. With a cooling capacity of 14,000 BTU, it is well-suited for medium to large spaces, effectively cooling areas up to 550 square feet. One of its standout features is the innovative duo hose design, which enhances air circulation and prevents hot air from re-entering the room, offering a more efficient cooling experience.
Its inverter technology is impressive as it uses significantly less energy—over 40% savings compared to standard units—making it an eco-friendly choice. The ultra-quiet operation at just 42 dB is also a major plus, ensuring a peaceful environment while it runs. Portability is another strong point. Despite weighing 76.8 pounds, the design allows for easy movement, especially with built-in handles. The smart Wi-Fi capability enables convenient control via the Midea Air app or voice commands through Alexa and Google Assistant, adding a modern touch.
There are some considerations. While the duo hose design enhances efficiency, it may require more complex installation compared to traditional single hose units. Additionally, the unit's weight could make it challenging to reposition frequently, especially for those with physical limitations. The noise level can vary, with a peak at 52.6 decibels when running, which might still be noticeable in very quiet environments. Maintenance involves regular cleaning of the dust filter, which is manageable but necessary for optimum performance.
With its excellent cooling performance, energy efficiency, and smart features, the Midea MAP14HS1TBL is a great choice for anyone looking for a powerful and efficient portable air conditioning solution, especially for those prioritizing quiet operation and smart technology.
