Review on 🚗 Versatile Retractable Portable Car Fans: 4-Speeds for Headrest & Rear Seat, Small Cooling Vehicle Air Fan with Quiet Operation - Rechargeable & Battery Operated, 360 Degree Rotatable USB Fan for Baby, Puppy, SUV by Brandon Woodson

The fan is definitely a lot less powerful than I hoped (4 settings and all the same) and doesn't work when not connected to a power supply source with the supplied cable. It's okay because I have a car charger with a USB port, but still. I thought maybe I put the lithium battery in the wrong way round, but it doesn't work either way. It does the job, but I won't recommend it to anyone, nor will I buy it again.
