We bought this fan to use in the car on hot days when we take my kids to the parks or to the zoo. It has great battery life. I think it took almost 4 or 5 hours for us (didn't have time). The legs can bend and stay where you put them. In addition, the front of the fan is too small for little fingers. So I feel safe with my 2 year old holding it alone. It's not noisy at all. Just a naked rumble. It also has 3 fan speed settings. Easily fits in a diaper bag or stroller case. A lightweight. I plan to buy a second one so my kids don't have to share it. 😂
