Review on O2COOL 5-inch Portable Fan Battery Operated, 1 Unit, Grey by Andrew Choukline

. I have used several laptops over the years but this one fits perfectly. I tried it at home just to make sure it lived up to its claim and it really does. Since it doesn't open all the way, at least on the two I bought, I sometimes have to rotate the batteries in their slot to get the fan working, but once it kicks in it works fine. If you're half asleep and want to move or adjust it, feel safe because the blades are covered in a grille front and back that even looks like it's designed to keep little fingers away from moving parts. Airflow is too noticeable at 2-1/2 feet with an anticipated decrease in airflow to be expected. I imagine waking up early in the morning and turning the fan on minimum so that humid air from the tent doesn't blow in my face. This action is easy to perform with a simple slide switch on the side. All in all a good little tent fan that I would recommend to family or friends and would buy again if it wore out. UPDATE: The device has been running continuously for 38 hours. at high speed and the fan still felt 24 inches away and it still worked. Looks like the perfect personal tent fan.
