Frequently Asked Questions

Q: How does the USB evaporative air cooler work?

A: The ROFAELEC evaporative air cooler draws warm ambient air through a water-saturated tank. As the air passes over the water, it cools down naturally and is pushed out as a refreshing, humidified breeze. Simply fill the top water tank with clean water (or add ice for extra cooling), plug the USB cable into any compatible USB power source, and enjoy instant cool airflow.

Q: What USB power sources are compatible with this cooler?

A: This cooler is compatible with any USB power source operating under 20V, including laptop USB ports, USB wall adapters, and portable power banks. This makes it extremely versatile for home, office, and travel use.

Q: Can I use ice in the water tank?

A: Yes! Adding ice cubes to the water tank enhances the cooling effect significantly. This is especially useful on hot summer days when you want maximum refreshing airflow from your personal cooler.

Q: Is this cooler suitable for large rooms?

A: The ROFAELEC portable cooler is designed as a personal space cooler, ideal for small to medium areas such as a desk, bedside table, or a small bedroom or dorm room. It is not intended to replace a full-sized air conditioning unit for large spaces.

Q: How do I clean and maintain the water tank?

A: For best performance, use clean, fresh water and empty the tank when not in use for extended periods. Rinse the tank regularly to prevent mineral buildup. Always unplug the unit before cleaning.
