Review on 🌀 Smartele FF16 Floor Fan - Rechargeable Outdoor Fan - Waterproof Portable Fan - Cordless Industrial Fan - Air Circulating Fan With 15000mAh Battery - Up to 30 Hours Runtime - Stepless Speed Control - Ideal for Garage, Barn, Gym, Patio, Camp - Hurricane 16 by Darin Merriwether

Fresh out of the box, this fan charges quickly (I plugged it into the charger, cooked dinner and did some chores and came back to check but it was already charged). It pushed out an incredible amount of air, and while I chose it for my Hurricane stash to provide some airflow when the power goes out, I think I'll be using it in the garage and other places that don't have good airflow to have. This fan is really good! Haven't turned off the power completely to see how long it really lasts, but after an hour there was no sign of slowing down. Very happy with this fan!
