Frequently Asked Questions

Q: How does the USB mini air cooler fan work?

A: The fan draws warm ambient air and passes it over a mist generated by its dual spray nozzles. The evaporation of the fine water mist lowers the air temperature before it reaches you, creating a refreshing cooling effect. Adding ice cubes to the 880ml water tank enhances the cooling output even further.

Q: What power source does the Houselin USB air cooler fan need?

A: It is powered via a USB Type-C cable (included, 1.2m long) at 5V/5W. You can connect it to a USB wall adapter, laptop, desktop computer, or a portable power bank — making it extremely versatile for home, office, and camping use.

Q: How loud is this mini air cooler fan?

A: The fan is engineered with a low-noise motor designed for quiet operation, making it suitable for use while sleeping, studying, or working. It runs quietly across all three speed settings.

Q: Can I use it as a humidifier or night light only?

A: Yes! The 7-color adjustable night lamp and the humidifier mist functions can be used independently from the fan, giving you flexible control over your environment at any time of day or night.

Q: Is this fan suitable for camping or outdoor use?

A: Absolutely. Its compact size (255 × 153mm) and lightweight design (586g) make it easy to pack and carry. Simply connect it to a portable power bank and you have instant cooling wherever you go.
