Frequently Asked Questions

Q: How does this silent desktop air cooler work?

A: This desktop air cooler uses dual ultrasonic misting technology to convert water into an ultra-fine 4.5μm mist, which evaporates rapidly as air passes through it, lowering the surrounding air temperature. You can add ice to the water tank to boost the cooling effect further.

Q: Will the mist make my desk or belongings wet?

A: No. The 4.5μm mist particles are so fine they evaporate almost immediately upon release. Even during prolonged use, the mist will not dampen your skin, clothing, or desk surface.

Q: What power source does this fan cooler use?

A: The cooler is powered via a standard USB connection, making it compatible with USB wall adapters, laptops, power banks, and other USB power sources. It operates at under 20V for safe, energy-efficient use.

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

A: The sealed water tank holds at least 700ml, which significantly reduces how often you need to refill it during the day. A built-in condensation collection tray at the base also captures excess moisture for easy drainage, helping keep your workspace clean and dry.

Q: Can I use the timer so it turns off automatically while I sleep?

A: Absolutely. The built-in timer has four settings — 2, 4, 6, or 8 hours — so you can set it to switch off automatically, making it ideal for nighttime use or when you're away from your desk.
