Review on 🌬️ Stay Cool on-the-go with the Upgraded Portable Waist Clip Fan - 8000mAh Battery Operated USB Cooling Fan for Outdoor Activities by Stephanie Traub

I'm not 100% sure what caused this problem but I've had this ventilator for 3 months. I recently turned it on/charged overnight for the first time. Maybe after about 3 months of light usage the battery will get weaker? But I think the problem was that this fan has no overcharge prevention function. At my job I worked the whole shift for 4 hours with the fan on 2nd speed and after that there was still juice left. But now that I've had 1 charge all night, my fan battery will be dead before my shift is over. Buyers, don't make my mistake, turn off your fans immediately when you see the green light indicates full charge. Up until this release, the fan was great where it counts: high winds and strong shirt clips that don't break easily.
