- Initial Use Recommendation: For optimal performance and longevity, fully charge the battery before first use. - Low-Power Protection Function: The Feng fan is equipped with a low-power protection mode. When battery levels drop below 10%, the fan automatically reduces its speed to conserve energy. For instance, at 8% battery, the fan will limit maximum speed to Gear 8 and will continue to adjust as power decreases. - User-Friendly Control Operation: Operating the fan is simple and intuitive. There is no infinite encoder knob and no self-check required at startup. You can turn the fan on or off by long-pressing the power button from any position. Quickly rotate the knob for immediate access to the highest or lowest speed, or adjust gradually by turning the knob slowly for single-speed increments. - Smart Digital Display: The fan features a built-in digital screen that shows real-time battery percentage while charging or in operation. It indicates the current charge level (displaying "100" when fully charged) and displays the selected gear level during adjustments, reverting back to the battery level automatically afterward. Key Benefits: - Perfect for personal use at home or in the office, offering efficient cooling when you need it most. - Ideal for outdoor activities such as camping or picnics where power conservation is essential. - Great for areas with limited power access, thanks to its low-power protection feature that maximizes battery life. With its combination of intelligent features and user-friendly design, the Feng fan stands out as a reliable cooling solution that adapts to your needs while ensuring efficient energy use.
