Review on 🌀 Stay Cool and Comfortable with OUTXE Hanging Neck Sports Fan: Explosion-Proof Battery, 4000mAh, USB Rechargeable, Hands-Free, Personal Wearable Neckband Fan by Chrissy Ramirez

This is a nice little personal fan, but it can be used for other purposes. You can put it on the table and have one fan for yourself and one for a friend. just aim it! The fans have 3 speeds. Also, the small fans can be removed and you can see that it is USB only, and the part you wear around your neck has a USB connector socket. This serves two purposes, you can plug the fan header into any USB power source and you have a fan. You can also plug other things into your neck like a USB flashlight or even charge your phone. With a capacity of 4000 mAh, that should be enough in a pinch! All in all it's a nice little device and I really like it.
