Power Connection
The ERYUE 3 Heads Car Fan is powered via a USB connection. Connect the USB cable to a compatible USB power source in your vehicle, such as a USB port or a USB car charger adapter. Ensure the power source provides sufficient voltage (USB 5V 2.1A) for optimal performance.

Mounting the Fan
The fan is designed for clip-on mounting. Securely attach the fan base to a suitable surface in your vehicle, such as the dashboard or center console, ensuring it does not obstruct your view or interfere with vehicle controls. The base should be stable to prevent movement during driving.

Adjusting Fan Position
Each of the three fan heads can be rotated 360° horizontally and adjusted up or down. This allows you to direct airflow precisely where needed, providing personalized cooling for different occupants or areas of the vehicle.

Operating Instructions
Power On/Off and Speed Control
Once connected to a power source, use the push button switch located on the fan base to turn the fan on or off. Pressing the button cycles through the two available wind speeds (low and high) to suit your cooling preference.
Airflow Adjustment
Individually adjust each fan head by rotating it 360 degrees or tilting it up and down. This allows for precise targeting of airflow to different areas of the vehicle, maximizing comfort for all passengers.

Maintenance and Care
Cleaning
- Ensure the fan is powered off and disconnected from its power source before cleaning.
- Wipe the exterior of the fan with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the ABS plastic material.

- Do not immerse the fan in water or any other liquid.
