This lightweight, multi-position fan is designed for everyday cooling—whether you’re commuting, sitting at a desk, or spending time outdoors.

How long will the battery keep the fan running?

Runtime depends on the selected speed: low settings extend battery life while higher speeds consume more power. With the built-in 4000mAh cell, expect several hours of continuous use—engineered for whole-day convenience on lower settings.

What makes this fan easy to carry and use while traveling?

The TUNISE fan folds flat at a 180° hinge and comes with a neck strap so you can wear, hold, or set it on a surface. Its compact footprint fits backpacks and totes, and the simple one-button control changes speeds and shows power at a glance.

How quiet and adjustable is the airflow?

• Ultra-quiet operation—under 15 dB on low
• Six-step speed adjustment including simulated natural wind
• One-button control to cycle through speeds quickly

Can this fan charge my phone in an emergency?

Yes—the fan’s battery can act as a power source for small electronics. When the fan isn’t in use or when you need a quick boost, connect your device via the fan’s USB output to transfer charge.
