Frequently Asked Questions

Q: How does the TEC cooling technology work in this portable neck fan?

A: The fan uses TEC (Thermoelectric Cooling) superconducting cold aluminum technology, which rapidly transfers heat away from the cooling plate, dropping its surface temperature by up to 16°C in seconds. When held near or worn around your neck, it delivers a refreshing, cool sensation without water or ice.

Q: How long does the 4000mAh battery last on a single charge?

A: Battery life varies depending on your chosen fan speed and wind mode. At lower speed settings, the 4000mAh battery can provide several hours of continuous use. Higher speeds and the active TEC cooling feature will draw more power. Charging is done conveniently via a standard USB cable (5V).

Q: Can I use this fan while it's charging?

A: Yes, the fan supports both USB-powered and battery-powered operation. You can plug it into a USB power source and use it simultaneously while it charges, giving you uninterrupted cooling.
