Frequently Asked Questions

Q: How does the portable evaporative air cooler work?

A: This portable air cooler uses dual ultrasonic atomizers to convert water into a fine cool mist, which is then blown through a cooling pad to lower the temperature of the air. The result is a refreshing, cool airflow that can reduce ambient temperature by up to 50°F — all without expensive compressors or refrigerants.

Q: What power source does this mini air cooler use?

A: The air cooler is USB-powered (DC 5V / 2A), making it compatible with USB wall adapters, power banks, laptop USB ports, and car USB chargers. This means you can use it virtually anywhere — at home, in the office, or on the road.

Q: How large a space can this air cooler effectively cool?

A: This is a personal/desktop air cooler designed to cool the immediate area around you — such as a desk workspace, car seat, or bedside table — rather than an entire large room. It is ideal for personal use in small to medium spaces.

Q: How often do I need to refill the water tank?

A: The 1,000ml tank at high spray mode (120ml/h evaporation) will last approximately 8 hours before needing a refill. At low spray mode (80ml/h), you can get up to 12+ hours of continuous operation. You can also add ice cubes to the tank for an extra boost of cooling.
