I have a second fan and they both had the same problem. Power it up with plenty of airflow cooling our first walk with it. Then when you use it the second time after 30-60 seconds, it turns off, turn it on again and it turns off. After I charged it and the same thing happened, I changed it, but unfortunately the same thing happened. Don't buy this if you need to keep your kid cool (what's the point)!
