4 in 1 Portable Waist Clip Fan - 12000mAh Battery Operated 22h Long Last USB Rechargeable Personal Belt Fan & 3 Speeds 7.01 m/s Strong Airflow Hands-Free Necklace Fan for Gift

【Strong Wind】 Adopting the principle of brushless motor and fanless fan, we widen the diameter of the air inlet to 6.8cm, and the diameter of the air outlet to 5.5cm*2cm, driving a large amount of air convection and providing you with strong wind power. The fan has three adjustable speeds so you can tailor the airflow to your needs. And with a hands-free design, you can move freely without any restrictions.

【Durable】The portable mini waist fan is durable. It is made of high-quality materials that can withstand even the harshest conditions. Whether you're working in hot, humid weather or a dusty and dirty environment, this fan will keep you cool and comfortable. The built-in 10000mAh battery supports the fan to run for up to 18 hours, even at the lowest speed, enough to keep you cool all day at the workplace or outdoors.
