Best portable air-conditioner for fast cooling

Black & Decker 14,000 BTU Portable Air-Conditioner Unit with Remote and LED Display

When you’re shopping for a portable air-conditioner, looking for something that cools you down, and does it quickly. Keep an eye out for the energy output — the higher the output, the faster the cooling system.

This minimizes the ventilated hot air inside. This model comes with an LED screen, remote control and automatic operation. This means that if the power goes out, this unit will come back on automatically.
