The ZUKBEN Portable Air Cooler is a 3-in-1 device that functions as a fan, humidifier, and air cooler. It features three wind speeds, a 1000ml water tank, a 90° oscillation, and a 1-9 hour timer. With quiet operation and USB power, it’s ideal for personal use in small spaces like bedrooms, offices, or camping. Adding ice enhances cooling, but it’s not a full air conditioner.
