【Dual Fan Heads – Powerful & Quiet Cooling】
The Hayousui USB car fan features two independently controlled fan heads, powered by a high-performance brushless motor and 100% pure copper spindle for a strong, steady airflow. Engineered for quiet operation (under 30dB), it delivers double the cooling—perfect for keeping babies, kids, and pets comfortable in the backseat without disturbing their rest.

【USB Powered & Easy Installation】
Compatible with 5V/2A power sources, this car fan works with most 12V/24V vehicles including SUVs, trucks, vans, and RVs. No battery needed—just plug in via USB-C and clamp it securely onto rear seat headrest bars. The adjustable spring clamp fits post distances from 4.33" to 5.51". Please measure your headrest posts before purchase to ensure compatibility.

【Customizable Airflow & Dual LED Lights】
Each fan head offers 3 adjustable speeds (low/medium/high) and can be turned on/off independently to suit passenger comfort. Built-in LED lights on each fan provide two brightness levels for added visibility during nighttime travel—great for families with kids.

【Flexible 360° Rotation for Full Coverage】
Mounted on bendable silicone hoses, both fans rotate 360° vertically and horizontally, allowing you to aim airflow exactly where it's needed. The compact, lightweight design takes up minimal space, while the safety grid protects curious little fingers from the blades.

【Multi-Use & Air-Purifying Benefits】
Ideal for use in cars, trucks, boats, and RVs, this rear seat cooling fan helps circulate air, defog windshields, and remove cigarette smoke, dust, and pet odors. An energy-efficient way to improve in-vehicle comfort and air quality for all passengers.
