BLACK+DECKER 8

1. BLACK+DECKER 8

  • Brand: BLACK+DECKER
  • Manufacturer: BLACK+DECKER

The BLACK+DECKER 8,000 BTU Portable Air Conditioner is designed for medium-sized rooms up to 350 sq. ft., making it an excellent choice for bedrooms and living spaces. This 3-in-1 unit functions as an air conditioner, dehumidifier, and fan, offering year-round utility. Its top-mounted LED display and remote control enhance usability, while the included window installation kit simplifies setup. The unit is highly portable, thanks to its lightweight design, side handles, and caster wheels.

In terms of performance, this model delivers reliable cooling for small to medium spaces, but its 6.2 SEER rating indicates average energy efficiency. At 52 dB, the noise level is moderate, suitable for daytime use but potentially disruptive during sleep. The auto water evaporation feature minimizes maintenance, and the slide-out washable filter ensures easy cleaning. However, its limited cooling power (4,100 BTU DOE) may struggle in extremely hot conditions or larger rooms.

Pros

  • Portable design with caster wheels and side handles
  • User-friendly remote and LED control panel
