Review on 🌬️ Next-Gen Portable Fan with LED Lights - Rechargeable for Baby Strollers, Desks, Travel, and Personal Use - Charger and High-Performance Batteries Included - Eco-Friendly USB-Powered Cooling Fan by Ronnie Saylor

I use this product when I'm in a restaurant or other place where it's tight and difficult to breathe. I didn't actually have rechargeable batteries before and they drained the batteries very quickly. Like less than an hour. However, when I bought the rechargeable batteries that came with the fan, they actually lasted about 7 hours. I love it and bought two so I can rotate devices and always be sure I have a charged device. It's also good for keeping the kids cool in the stroller.
