15600mAh Rechargeable Battery Operated Drum Fan, 12 inch Yellow Industrial High Velocity Floor Fan, Shop Fan for Camping Gym Garage Outdoor Indoor, AI-F600Y

This fan is exactly what we need when the power goes out. My autistic son doesn't do well without his fan noises so this is perfect! I will be buying a few more for other rooms.

No electricity in my barn so this is perfect! I positioned them atop individual stalls for constant efficient air flow! Perfect for hot summer days!

Took this fan to a car show. Set it under my tent. 90 degrees plus and it worked perfectly.

The media could not be loaded. I ran four consecutive tests on the Airvention 15600mAh Rechargeable Battery Operated Drum Fan,16 inch Black Industrial High Velocity Floor Fan to see how long a fully charged battery would last.For each test I let the battery charge run completely out, until the battery was dead. Next I detached the dead battery from the fan and I fully charged the battery (a fully charged battery is indicated when the blue flashing power indicator lights turn off completely while plugged into the electric outlet), I attached the battery to the fan and powered the fan on.PLEASE NOTE: I did not charge any devices while running the fan; I ran the fan only powered solely by the fully charged battery.TEST #1 - With a fully charged battery, on the medium speed setting (right in the middle on the speed dial / knob) the fan ran for 25 straight hours on battery power only - QUITE IMPRESSIVETEST #2 - Again with a fully charged battery, on the medium speed setting the fan ran for 25 straight hours on battery power only - QUITE IMPRESSIVETEST #3 - Again with a fully charged battery, on the highest speed setting the fan ran for 4 straight hours on battery power only - VERY DISAPPOINTINGTEST #4 - Again with a fully charged battery, on the highest speed setting the fan ran for 4 straight hours on battery power only - VERY DISAPPOINTINGWhile running the fan continuously powered by a fully charged battery, consistently at the medium speed, the fan exhibits impressive results….running nonstop for 25 hours!However, when ran continuously by a fully charged battery, consistently at the highest speed, the fan’s performance disappoints running for only 4 consecutive hours.I do not how the fan will perform if I run the fan on a fully charged battery while charging my cell phone. However, I will share my results if I run this test.PLEASE NOTE: If the fan ran for a longer period of time, on a fully charged battery, on the highest speed setting, I would have given it five stars.PLEASE NOTE: On the highest speed the fan is a bit noisy, but not to the point where it is distracting. Also the fan arrives fully assembled.

Best fan for multi use. It has been hot and I bring this in my truck. I use it for my dog in hot days if we both have to kill some time in the truck. I use it for workouts in the garage. Super recommend

doesn't power on without being plugged into wall. Does not work w battery alone which is sole reason I bought it. Find another brand

This item is amazing. The battery last more than 10 hours. It's not heavy at all.

Perfecto
