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 Efraine Cruise

These fans are quiet and do a good job of moving the air in my caravan beds to 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.
