Review on 🌬️ Stay Cool Anywhere with the YXwin Stroller Fans Mini USB Desk Clip on Fan - 40 Hours Battery Life, 360° Rotation, 4 Speeds - Perfect for Outdoor/Indoor Baby Car Travel, Office, Camping, and Library by Christine Sandoval

What I like about this fan: 1. Dual battery installation allows you to extend the life of the fan. This fan will run at least all night on medium to low settings.2. The ability to connect it to a USB power adapter extends the fan's lifespan almost as long as you want it to. Instead of a High-Medium-Low setting, this fan has an adjustment dial that allows you to set the speed to high or low to your liking. This is good if you just need a little breeze or if you're worried about fan noise.4. It's probably as quiet as you can make a fan. The motor is quiet (although you may hear it more on the lowest settings) and on high settings you only hear the fan blades spinning (which is to be expected).5. This fan blows a decent amount of air. Simply put, it performs as well as you would expect from a fan of this size.6. The clamp function is very useful. Overall I am very happy with this fan. Highly recommended.
