Large Water Tank: Equipped with a 3.17 gal/12L water tank, this fan mister delivers lasting misting through three adjustable modes: maximum continuous, minimum continuous, and interval spray. The setup lowers refill frequency and maintains smooth cooling for a more consistent experience. When the water in the bucket is low, turning on the humidification function will cause noise. When using the humidification function, please add water in time Adjustable Wind Levels: Powered by a 2400RPM motor, our portable mister provides strong and quiet circulation. Four adjustable wind speeds let you move easily between gentle and powerful cooling, supporting various settings while offering steady comfort and refreshing airflow. During spraying, water mist collects into droplets, which flow through the panel into the water channel on the cover and back into the water bucket, preventing the floor from getting wet High-Capacity Battery: This VEVOR water misting fan features a 20000mAh battery that charges in about 9–12 hours and delivers long cooling after each charge. It supports daily use and outdoor activities with steady airflow and mist, letting you enjoy refreshing comfort wherever you go Adjustable Light Modes: Our water cooling fan provides three lighting options that let you adjust brightness for gatherings, camping, or daily use. Its 120° horizontal swing and 120° vertical tilt support even airflow and light coverage, giving you comfort from multiple angles
