Review on 💨 WIOR 5V 1.5A Mini Portable Waist Fan – Rechargeable USB Powered Fan for Camping, Traveling, Cycling, Working, and Fishing – Low Noise with 3 Speeds and Hanging Design by Bret Wong

The best thing about this fan is the hook you can attach your shirt to to keep the air circulating instead of pulling the shirt into the fan. It's not easy, it's not small. I would compare it to the size of an average man's clenched fist, maybe a little more. It's not small and you can't really hide it. But I sweat just thinking about sweat and it helps me stay cool. It's not perfect, but it definitely does what I wanted it to do. Add a hand fan for the neck area and sweat will be minimal.
