Brand: SHENVITASO

Color: White

Features:

• 【Battery Backup for Day & Night Ventilation】Built‑in 7500mAh rechargeable lithium battery (≈31Wh)​ keeps the exhaust fan running after sunset or during cloudy weather. After 4–6 hours of charging, the fan can operate for up to 9 hours, ensuring continuous airflow when standard solar fans stop working. Automatically turns on when power is available—no daily reset needed.
• ​【Efficient 8‑Inch Ventilation Fan】​The 8‑inch solar exhaust fan delivers up to 430CFM airflow, providing strong ventilation for medium to larger spaces such as chicken coops, greenhouses, or garden sheds over 180 ft². Please note: airflow may be too strong for very small or tightly enclosed setups. For smaller spaces or more enclosed areas, we recommend choosing the 6‑inch version for more balanced airflow.​ Selecting the right fan size helps maintain comfort and efficiency.
• 【Real Dual Charging Flexibility】Comes with a 25W solar panel (21.5% efficiency) and 16.4FT waterproof cable, giving you freedom to install it on rooftops, fences, or outdoor walls. The Type-C port offers a secondary charging method via household power. Whether off-grid or home-based, your airflow remains uninterrupted day or night.
• 【Low-Noise Design】Designed for quiet operation, the fan runs below 36dB, making it perfect for use in sensitive environments like chicken coops and pet shelters. Gentle airflow ensures healthy air circulation without startling animals. Built with durable ABS material, suitable for seasonal outdoor use.
• 【Easy Setup & Versatile Application】Simple installation with included screws—no wiring required. Just drill a 7-inch hole, mount the fan, and set the solar panel in a sunny location. Perfect for chicken coops, greenhouses, attics, RVs, sheds, barns, and more. All-in-one solution for summer ventilation.
