It offers a good cooling capacity of 14,000 BTU (ASHRAE) and 10,000 BTU (DOE), along with a heating function of 12,000 BTU, making it suitable for use throughout the year.

With a noise level of 54 dB, it operates relatively quietly, making it a good option for bedrooms and living rooms. It includes smart features like Wi-Fi connectivity and voice control through Amazon Alexa or Google Assistant, which add to its convenience.

The Follow Me remote control is a standout feature, allowing for more precise temperature control. Portability is ensured with its compact dimensions and included window installation kit, making it easy to set up and move as needed. However, it's important to note that it is not Energy Star rated, which may be a consideration for those looking for highly energy-efficient models. This unit is well-suited for those seeking a multi-functional portable air conditioner and heater with smart features and reliable performance, particularly in mid-sized to larger rooms.

This unit can effectively cool or heat rooms up to 550 sq. ft., making it suitable for bedrooms and medium-sized spaces. Its portability is enhanced by a compact form factor and wheels, allowing for easy maneuvering between rooms. However, it weighs 57.6 pounds, which might be cumbersome for some users to move frequently.

The energy efficiency ratio (EER) is 5.8, which is not the highest, meaning it may not be the most energy-efficient option available on the market.

The unit includes a smart control feature that allows for Wi-Fi connectivity and voice control via Amazon Alexa and Google Assistant, adding convenience for tech-savvy users.

Maintenance is straightforward with the dehumidifier function and easy-to-install window kit included.

The BLACK+DECKER 12,000 BTU Portable Air Conditioner is designed to cool rooms up to about 550 square feet, making it a solid choice for bedrooms or medium-sized living spaces. It offers a decent cooling capacity at 12,000 BTU (although the official DOE rating is 7,000 BTU), which means it can handle typical summer heat effectively. The unit operates at a noise level of 52 dB, which is relatively quiet but might still be noticeable during very quiet moments like sleep. One thing to note is its Energy Efficiency Ratio (EER) of 5.8, which is on the lower side, so it may consume more electricity compared to more efficient models, and it lacks an Energy Star rating.

Portability is a strong suit here — the unit includes casters and side handles, so moving it between rooms is fairly easy despite its 56.8-pound weight. You also get a handy remote control and a top-mounted LED display for easy temperature adjustments, along with a 24-hour timer and a 'Follow Me' feature that adjusts cooling based on the remote’s location. Maintenance is user-friendly, with a slide-out washable filter and an auto water evaporation system that reduces the need to manually empty water.
