pqins 5.5in Solar Fan with Battery – 30W Solar Powered Outdoor Ventilation (18600mAh)

Overview

Meet the pqins 5.5in Solar Fan with Battery, a compact, rugged solution for ventilating small outdoor spaces. It combines two hi-velocity 5.5-inch DC fans that push air quickly with a 30W solar panel and an 18600mAh intelligent battery. Daylight powers the fans and charges the battery, while excess energy is stored for dusk-to-dawn use. Built for outdoor environments, the system is waterproof and ready for easy placement with a 16.7 ft extension cable.

Performance is designed for real-world settings. The dual fans can reach up to 3800 RPM and deliver up to 720 CFM of airflow, making it suitable for chicken coops, greenhouses, sheds, cabins, and other compact spaces where air movement matters. The solar panel drives both the fans and the battery at the same time, enabling ventilation even off-grid. Airflow naturally rises on sunny days and tapers on overcast days, while the stored energy supports night-time operation.
