Solar Airflow, Even After Sunset!

“I wasn't expecting much, but this 25W Solar-Powered Ventilation Fan Kit with 4000mAh Battery Backup picks up sunlight crazy fast – even on an overcast day, I hooked it straight to my fan and got a slow, steady spin. No joke. One heads-up: the battery came completely dead. Just leave it in direct sun for a good 4–6 hours to wake it up. After that first charge, it's been running like a champ and holds power way longer than I thought. Honestly, it exceeded my expectations by a mile. Totally worth it.” - Banes
