FEATURES
DUAL POWER OPTIONS: Enjoy continuous cooling with flexible charging solutions. The high-efficiency monocrystalline solar panel (5V/80mA) powers the fan automatically in direct sunlight - simply wear it outdoors to activate. When indoors or in low-light conditions, the built-in 1000mAh battery provides reliable backup power. Easily switch between power sources with a long press of the control button.
360° ADJUSTABLE FAN: Direct airflow precisely with a fully rotatable fan. The 7000 RPM motor delivers whisper-quiet cooling, while the full-cover safety grill prevents hair/finger contact. Tilt the fan 360° for comfort during workouts, hikes, or commutes.
SMART DISPLAY & 3-SPEED CONTROL: Track battery status in real-time with the integrated LED display. Adjust cooling intensity effortlessly using the tactile button to switch between three preset speeds (low/medium/high).
BREATHABLE & SUN-SAFE DESIGN: 10cm brim provides UPF50+ sun protection. Lightweight (56-60 cm adjustable headband) with moisture-wicking inner lining. Detachable fan module simplifies cleaning.
EXTENDED RUNTIME: Choose between 8-16 hours (1000mAh extended battery) or 4-8 hours (650mAh standard). Ideal for travel, sports, or outdoor work.
