Mini Portable Turbo Fan [16H Max] Personal, USB Rechargeable 4000mAh, Small Battery-Powered Pocket Fan with 5 Speeds - Brown

Patented Turbocharged Airflow: The portable turbo fan features two patented vortex technologies: Air Turbo and Air Jet. The airflow is accelerated and compressed by the air duct's turbine, resulting in a stronger wind and a more natural, refreshing breeze. 5-Speed Turbo Fan: This portable fan offers 5 speeds for powerful cooling. Simply press the power button to change the wind setting, a short press to cycle from low speed (3300 RPM) to high speed (6100 RPM), and a long press on any speed setting to turn it off. Up to 16 Hours of Cooling Time: The handheld fan comes with a 4000 mAh rechargeable battery (twice the capacity of a standard handheld fan), providing 3 to 16 hours of runtime (depending on the speed setting). You can charge it via a standard outlet, power bank, computer, or any other device with a USB port; a full charge takes just 3 hours.
Powerful and Energy-Efficient: This personal portable fan features a high-performance motor and an optimized air duct to maximize airflow while minimizing noise. Compared to other portable fans, it has a faster speed (6100 RPM) and a stronger airflow (4.8 m/s).
Portable and Desktop Fan: This mini portable fan comes with a cord and a non-slip mat on the bottom. You can hold it around your hand as a handheld fan outdoors and use it as a small desktop fan on a flat table indoors.
