Frequently Asked Questions

Q: How does this portable USB desktop cooling fan work?

A: This mini air cooler fan draws warm air over a water-saturated pad inside its 500ml water tank, releasing a cool, humidified mist through the front vents. The USB-powered motor circulates the cooled air toward you, creating a refreshing personal microclimate at your desk or bedside — no refrigerant or complicated setup required.

Q: How long does the 500ml water tank last on a single fill?

A: On the lowest fan speed setting, the water tank can last up to 24 hours. Higher speeds will use more water and reduce the operating time accordingly. Simply refill the tank with water (you can add ice cubes for an extra cooling boost) when it runs low.

Q: Can I use this air cooler fan outdoors or while traveling?

A: Absolutely! Because it's USB powered, you can plug it into a portable power bank, laptop, or any USB wall adapter, making it great for outdoor picnics, camping, travel, or any situation where you need personal cooling without access to a traditional wall outlet.

Q: Is this fan noisy? Will it disturb my sleep?

A: This fan is designed for quiet operation, making it suitable for use in bedrooms and offices. The built-in night light and gentle hum of the lowest speed setting are perfect for nighttime use without disrupting your rest.
