The BLACK+DECKER 10,000 BTU Portable Air Conditioner is suitable for cooling rooms up to 450 square feet, making it an excellent choice for bedrooms or small living areas. One of its major strengths is its portability, thanks to its casters and side handles, which allow for easy movement between rooms. Additionally, it has a 3-in-1 functionality, serving as an air conditioner, dehumidifier, and fan, providing versatility for different weather conditions.

The unit comes with a remote control and a top-mounted control panel with LED display, making it user-friendly. The slide-out washable filter is a convenient feature for maintenance, and the auto water evaporation system reduces the need for manual water removal. The 24-hour programmable timer adds flexibility in managing cooling schedules.

On the downside, its Energy Efficiency Ratio (EER) is 6.7, which is relatively low, indicating it may not be the most efficient option in terms of energy consumption. Additionally, the noise level is 52 dB, which might be noticeable, especially during sleep. Despite these drawbacks, the included installation kit simplifies the setup process, and the unit's cooling power is sufficient for the specified room size. This air conditioner is ideal for users looking for convenience, portability, and multi-functionality in a single device.

Its 10,000 BTU cooling capacity effectively serves this space size. The unit offers three different cooling and fan speeds, allowing you to tailor the airflow to your comfort.

It also helps reduce humidity with a dehumidification capacity of about 2.7 pints per hour, improving comfort on muggy days.

Noise at maximum settings can reach up to 60 dB, which is typical but might be noticeable in very quiet environments. Installation is typical for a window unit, requiring a compatible window and some setup effort.

The included air filter helps keep the air cleaner but may need regular cleaning or replacement to maintain performance.
