Review on 🌬️ NuPow 8-Inch USB Desk Fan: Portable, Quiet, and Space-Saving for Bedroom, Office, or Home by Randy Robinson

The connector on the back of the fan needs a little tweaking to get it to turn on, but when seated properly it's fine. I didn't use batteries so I don't know about it. I use it under my desk for air circulation. It's so quiet I forget to turn it off. If it didn't have a nice little colored indicator on it I wouldn't know it was there. Very adaptable and versatile. Also very easy. The different speeds are great. I love it. And the price was right.
