Review on 🔋 Treva 5 Inch Battery Powered Clip Fan – Slim, Portable & Multi-Directional Cooling with Adjustable Head – Ideal for Travel, Outdoor Activities, Camping, Car, Office Desk, Baby Stroller – 2 Units, Khaki by Jerome Pritchard

These fans are quiet and move the air in my trailer beds well and keep them cool. Children could sleep peacefully without fan noise. Running at high speed drains the batteries a little faster. They snap into place, but the batteries make the clip a bit heavy. I had to make sure I fixed them as securely as possible so they wouldn't fall off. I also used one on the shower curtain rod to force air out of the trailer bathroom vent and it worked well. I would buy them again.
