Frequently Asked Questions

Q: How does this portable mini air cooler work?

A: This personal air cooler uses evaporative water-cooling technology. Water from the 380ml tank is drawn over an internal cooling element, and the built-in fan circulates the cooled, humidified air outward. It works best in warm, dry environments and is ideal for personal use at a desk or bedside rather than cooling an entire room.

Q: What do I need to power the USB air cooler?

A: It runs on a standard DC 5V USB connection, drawing between 0.2A and 1.4A depending on the selected fan speed. You can power it from a laptop USB port, a USB wall adapter, or a compatible power bank — no dedicated power outlet required.

Q: How long does one tank of water last?

A: The 380ml water tank provides approximately 3 to 8 hours of continuous use. The actual duration depends on the ambient humidity of your environment and the fan speed setting selected — lower speeds and higher humidity extend run time.

Q: Is this air cooler noisy?

A: On its lowest setting the unit operates at just 30 dB — quieter than a typical whisper — making it well-suited for office work, studying, or use while sleeping. Medium and high settings reach 38 dB and 46 dB respectively, still quieter than most standard desktop fans.

Q: Can I use ice in the water tank?

A: The tank is designed for water only. Adding ice cubes directly is not recommended as it may affect the internal components. For enhanced cooling, you can use chilled or cold water when refilling the tank.
