Review on 🌀 AURTEC Portable Neck Fan - Hands-Free Bladeless Neck Fan with LED Display, Personal Summer Cooling Neck Fan - 3 Speeds, 4000mAh Rechargeable - Blue by Trent Kraft

In two high speed tests I got 3-4 hours of operation, less than the advertised 5-10 hours for the fan. Charges in about 8 hours. Pros: Bladeless is better if you have long, tangle-free hair. The side effect is that the mosquitoes don't touch your face, they obviously don't like strong winds. USB-C is used for charging. Very good for high water. Well, if it's around your neck, for example, you can't talk to another person. It's quite heavy, you can't walk in it, it bounces up and down, and it's very uncomfortable. There's another one you can bend a bit to better fit and align the fan.
