How Does the cooling work?

Devices use a miniaturized cooling mechanism that generates a refreshing breeze through its vent system. They are designed to provide instant cooling relief in warm environments.

The long-lasting rechargeable batteries typically provide up to 10+ hours of use on a full charge, depending on the cooling mode used.

You can charge the devices with a standard USB-C cable (included). Full charging usually takes 2–3 hours.

Is it safe to use on the skin or face?

Can I wear it all day?

Yes. The devices are lightweight and comfortable for daily wear. They can be worn on included lanyards, carried in hand, or clipped on to garment. The Nivi Neck Fan is designed to wrap around the neck for continuous cooling.

Does it make noise?

The cooling fan is very quiet — about the level of a soft whisper. It is suitable for use in public spaces, offices, or while traveling.
