DICMKY dual head car fan upgraded rechargeable design, built-in 2000mAh battery, can be used unplugged after fully charged. The fan body can be adjusted at any angle, which can blow both the front row and the back row, making the air circulation in the car smoother. It has retractable arms that can be pulled in to blow air in the back to keep passengers cooler; when not in use it can be folded behind the headrests without taking up too much space. It comes with a 70-inch long Usb to Typc-C charging cable that makes it very easy to charge it in the car. It has three adjustable wind speeds for different temperature conditions. If you often travel with your family in the summer, having one of these fans for your rear passengers is a great addition.
