**Portable Handheld Fan with Extended Battery Life & Phone Holder** **Long-Lasting Battery Life:** The handheld fan features an upgraded, large-capacity battery, providing up to 12 hours of continuous cooling on a full charge. More durable than other USB fans, it keeps you cool all day long. The portable fan operates with a simple one-button design. **Powerful Airflow & Low Noise:** Equipped with a new built-in brushless copper motor, this quiet fan's efficient power supply and conversion circuit maximize wind power while maintaining smooth, energy-saving, and environmentally friendly operation. The handheld fan offers three adjustable speeds, allowing you to switch settings as needed. **Detachable & Washable Design:** After some use, rechargeable fans inevitably accumulate dust. Our portable rechargeable fan features a detachable design: simply press both sides of the grille to easily remove it for cleaning. You can also remove the fan blades and wipe them clean simultaneously. (Note: Do not let water touch the motor and battery compartment.) **Integrated Mobile Phone Holder:** At the end of the battery-powered fan's handle, there's a small valve. Press it firmly, and the handheld fan miraculously transforms into a desktop fan with a convenient stand. Place your phone on the stand and enjoy a pleasant movie while relishing a cool breeze during summer. **Foldable & Ultra-Portable:** The handheld fan's handle boasts a 270° foldable design, allowing it to be used as both a handheld fan and a desktop fan. Perfect for school, its compact and portable design makes it an excellent choice for travel, workouts, barbecues, camping, watching ball games, and other outdoor activities. It's also ideal for providing cooling relief and reducing fever for babies at night.
