Review on 🔋 10,000mAh Portable Fan - Rechargeable Battery Operated Desk Fan with LED Light, 3 Modes, 360° Rotation - Personal USB Small Fan for Camping, Golf Cart, Indoor Gym, Treadmill, Office by Susan Forrest

We put this item to the ultimate test. Trip to Disney World! Attachable stroller fan. I checked the battery life at home before the trip. It ran for 23 straight hours at level 3 speed. Impressive! We used it every day at Disney World and on hot, muggy days my son was cool and comfortable in the stroller. He slept so soundly. Even under a raincoat that would otherwise be stuffy. My sister sometimes used it on her disabled scooter. she liked it. Five days of 12+ hours at Disney, and it never ended or died. In fact, I think it never went below 66% power reserve. We even plugged it in and used it in our hotel room at night. The LED backlight is cool, but we never used it. We've also never used it as a power bank to charge cell phones, so I can't comment on that. But judging by the power this thing has left at the end of the day, I have no doubt that it can get the job done during use. I can absolutely recommend this fan!
