Manufacturer description
The Koonie 10000mAh clip-on fan solves the problem most portable fans dodge: running all day without a cord. Its 10000mAh battery is rated for up to 24 hours per full charge, and the three 8-inch blades push real airflow instead of the token breeze you get from palm-sized USB fans. A 3-inch clamp grips desk edges, treadmill frames, golf cart posts, tent poles, and nightstands, and the head rotates 360 degrees both vertically and horizontally so you can aim air anywhere without moving the mount. Four settings give you three speeds plus an energy-saving mode for overnight use, and Koonie tunes…

Frequently Asked Questions
How long does the Koonie clip fan run on one charge?
Koonie rates the 10000mAh battery at up to 24 hours per full charge. That figure reflects the lowest speed or energy-saving mode; expect noticeably shorter runtime on speed 3.
How long does it take to fully charge?
About 6 hours with 5V-2A (10W) fast charging. The Type-C port works with laptops, phone adapters, power banks, and standard USB chargers.
Will the clamp fit my treadmill or golf cart?
The clamp opens to 3 inches, which covers desk edges, treadmill frames, golf cart posts, tent poles, and nightstands. Measure your mounting surface first if it's thicker than 3 inches.
Is it quiet enough to sleep or work next to?
Koonie designs the motor to stay quiet even at high speed, and includes an energy-saving setting alongside the three standard speeds for overnight or nap-time use.
Can I use it as a desk fan instead of clipping it?
Yes. It's a 2-in-1 design that sits on a flat surface as an 8-inch desk fan or clamps to an edge, and the head rotates 360 degrees either way.
