BLACK+DECKER’s BDMC10 is a compact desktop cooler that uses evaporative technology. It’s a simple, USB-powered solution for personal cooling when a standard fan isn’t enough.

The 0.5-liter water tank is the key. Fill it, and the three-speed fan pulls air through a moistened cooling curtain. This adds a noticeable chill to the airflow, a tangible difference from just moving warm air around. It works best in dry climates and within a few feet of your face, making it ideal for a focused desk or bedside setup.

The trade-off for its size is capacity. The tank lasts about four to six hours on a medium setting, so refilling is a part of the daily routine. It’s a focused tool, not a room cooler, but for direct, humidified relief at your workstation, it delivers.
