Review on KZOBYD Mini Handheld Fan 3-Blade: Rechargeable USB Powered Personal Pocket Fan for Office, Car, Travel - Green by Heather Preston

This little fan is great for cooling one person. The blades fold easily into a tube for easy storage (small size) and use as they unfold automatically when you remove the cap. Then the cover is fixed by placing it on the opposite side. This serves as a shield for the charging ports. There is a handy loop/strap on the side for easy carrying. I gifted this to my 6 year old son and he loves having a fan to carry around in the car and when we go away on hot days. The blades do an excellent job of moving a lot of air without hurting them if they "accidentally" touch them while spinning. A built-in 2000mA rechargeable battery powers the fan and is also available as a power bank feature with a USB-A port to connect other devices such as phones or music players. When used as a fan, this will last for many hours. Of course, if you're using it as a power bank, the runtime will depend on what you're charging. Overall this is a really cool product and it works very well. I highly recommend it!
