Portable Handheld Fan with 4000mAh Battery, 3-in-1 Personal Travel Fan

The ColdSky personal fan is equipped with a high-quality brushless motor and a 7-blade design that provides powerful airflow. Users can switch between 5 adjustable wind speeds with a single click, keeping them cool and comfortable whether they are working, sleeping, or relaxing.

Featuring a built-in 4000mAh battery and energy-efficient technology, the ColdSky battery-operated fan offers long-lasting battery life. The fan can run continuously for 7-20 hours, allowing users to enjoy a cool and comfortable experience without worrying about running out of power. This makes the fan perfect for travel, makeup, lash application, camping, outdoor activities, and indoor use.

The smart digital screen on the small fan displays the remaining battery life and speed level, making it easier for users to adjust the fan to the ideal wind speed and stay aware of when they need to charge it. This can prevent the fan from running out of power unexpectedly while used outdoors.

The 3-in-1 multifunctional design of the ColdSky fan allows it to be used as a handheld fan, neck fan, or desk fan. The adjustable 90° vertical design enables users to redirect the airflow and stay cool from any angle, making the fan suitable for various settings and scenarios.

Benefiting from silent motor technology, the ColdSky USB fan reduces noise while generating maximum airflow. Compared to competitors, the motor produces a noise level that is 30% lower at the same wind speed. This ensures the fan will not disturb users' work or sleep.

The cover of the ColdSky fan can be detached for easy cleaning by turning it counterclockwise. Additionally, the fan features a 2-in-1 non-slip base that can serve as both a fan holder and a phone holder, providing users with a convenient and versatile experience.
