Frequently Asked Questions
Q: How does the mini portable evaporative air cooler work?
A: The cooler draws warm air through a water-saturated evaporative pad, then uses the nine-leaf spiral fan to push cooled, moistened air out through the double-nozzle mist outlets. Filling the 500ml tank with cold water or ice cubes enhances the cooling effect significantly.
Q: What USB power sources are compatible with this air cooler?
A: This cooler operates at 5V and is compatible with any standard USB power source — including laptop USB ports, desktop computers, USB wall adapters, and portable power banks. It also features a built-in 1800mAh battery for cordless use.
Q: How large a room can this portable cooler effectively cool?
A: This mini evaporative cooler is designed for personal or small-space use, covering areas up to approximately 25 m². It is most effective as a personal desktop cooler in offices, bedrooms, or similar compact spaces rather than large open-plan areas.
Q: How do I clean or refill the water tank?
A: The tank features a large top-fill opening that makes refilling with water or ice cubes quick and effortless. For cleaning, simply remove the tank, rinse thoroughly with clean water, and allow it to dry before reassembling. Regular cleaning is recommended to maintain optimal mist quality.
