Review on 🌬️ O2 Cool Fan: Versatile 8 inch Portable Fan with AC Adapter - Battery or Electric Operated for Indoor and Outdoor Use, 90 Degree Tilt Feature by Ashlee Washington

Batteries just received and installed. I didn't expect the air outlet to be very strong, but I am very surprised that when using batteries whose name is NO Air, the stronger airflow actually comes from the back of the fan and not from the front as on the Photos shown where it's "o2cool. Then when using AC everything is fine - good strong airflow. Update: I believe the fan blades spin backwards when using batteries - or only very weak with batteries but they should be fresh As they came from Revain at the same time.. Works well with AC I already have AC fans, ordered this one for mobile use.
