Review on 5000mAh USB Rechargeable Handheld Fan by SAYTAY - Portable Personal Fan with 7-24 Hours Work Time, 5 Speeds, Ultra Quiet Operation, Phone Holder - Ideal for Office, Bedroom, Outdoor Use (White) by Tasha Price

So many speeds but since it's on the table next to me I set it to level 1 or level 2, even at those airflow speeds it's enough. At maximum speed, the airflow can be felt throughout the room from 15 to 20 feet away. I charged it fully and now it runs at level 2 for about 7.5 hours. The battery level is still at 75%, please update this review with the actual hours if the battery runs out. Given the accurate battery level readout, this is a nice little addition, especially as it easily shows the speed the fan is set to. Also, it's pretty quiet. All in all, this fan was added as an addition to my desktop.
