The KC-F20K is a foldable neck fan with a semiconductor cooling plate for hands-free airflow and localized contact cooling. Its flexible tube structure can be folded into a compact shape for storage and adjusted around the neck for different wearing positions. Three airflow levels allow users to balance cooling strength and battery runtime, while dual 800mAh batteries provide up to approximately six hours of fan operation. The KC-F20K also includes a brushless motor and an aroma function that allows compatible fragrance oil to be added at the designated air inlet. It is suitable for appliance retailers, travel accessory stores, online sellers and private-label personal cooling collections.
