Review on O2COOL 10-Inch Battery Operated Fan - Portable with Rechargeable Battery, Multiple Power Options - AC/DC Adapter, USB Port for Emergencies, Camping, Travel, Indoor & Outdoor Use (Orange) by Mark Colbert

I expected a charged battery to last me at least a few hours on a single charge, taking less than a minute to deplete , tried a few once fully charged and the same thing. As a result, I slept with a $50 piece of junk next to me in the heat. You can imagine it wasn't a happy night for me or my family at the campsite. I used to have many fans and this is the worst and most expensive. Stay away from this product.
