After fully charged, the portable fan can be used for about 3-5 hours (depending on the wind speed you choose). The product is equipped with a USB data cable, you can use chargers, computers, powerbanks and other equipment to charge the fan. LONG AIR OUTLET & LOW NOISE: The extended air outlet brings more air volume, which can quickly remove heat and help you stay cool.
