10000mAh Rechargeable Clip-on Fan

The F491 is an 8-inch portable fan powered by a 10000mAh battery that delivers up to 24 hours of runtime on a single charge. It operates on 12 volts with a 126-watt brushless motor and offers four speed settings plus an energy-saving mode. The sturdy 3-inch clamp and freestanding base suit desks, treadmills, golf carts and tent poles alike. Button controls and an included remote allow convenient operation from a distance.

Sustained Airflow and Quiet Operation

The brushless motor maintains consistent airflow across all speed settings without the drop-off common in smaller battery fans. Five wing-shaped blades move air at 14 feet per second while running quietly enough for sleeping infants or office calls. Fast 5V-2A charging restores the 10000mAh cell in about six hours, and the USB-C port accepts power from laptops, phone adapters or power banks for flexible top-ups during extended use.

360-Degree Positioning and Simple Setup

The fan head rotates 360 degrees vertically and horizontally, directing air precisely where needed without repositioning the clamp. The 3-inch clamp opens wide enough for thick desk edges or tubular frames yet remains secure on thinner surfaces. At 1.76 pounds the unit is light enough for travel but stable on its flat base. No tools or wiring are required — simply charge, clamp or stand, and press the button or remote to start.
