- Dual-head design with independent controls: The dual-head fan can be used as a single unit or as two separate fans; each head can be controlled independently to tailor airflow. The two fans double cooling power and improve air circulation, keeping you comfortable even in hot driving conditions, especially when the car AC is insufficient or unavailable. - Three speed settings: Low, medium and high. With the touch of a button you can tailor your cooling experience. The portable design is well suited for the rear seat and helps ensure both driver and passengers enjoy a comfortable ride by adjusting airflow to individual preferences and weather conditions. - Versatile charging compatibility: This auto fan runs on DC 5V and is compatible with power banks, car chargers and AC adapters. It works for larger vehicles such as trucks, SUVs and motorhomes. For optimal performance, the fan stops when the vehicle is off to save power and reduce fuel consumption. - 360-degree rotation: The improved design allows 360-degree rotation for flexible positioning and easy storage. You can adjust the angle to effectively cool both front and rear seats and provide refreshing airflow to rear passengers.
