Portable Solar Clip Fan

The EINSKEY Solar Hat Clip Fan is a lightweight, portable cooler that clips to hats, bags or gear for hands-free airflow during hiking, golf, fishing or other outdoor activities. Dual power modes let it run directly from its built-in solar panel or from the integrated 3.7V 300mAh lithium battery when light drops. Three button-controlled speeds adjust output to match conditions.

Dual Power And Charging

Switching between solar-direct and battery operation is automatic, so cooling continues in shade or cloud. The advanced IC charging circuit provides overcharge and overdischarge protection while a clear indicator shows charge status; a full charge takes 2 hours via the included cable. Two fans and two cables are supplied in the pack.

Runtime And Coverage

On battery power the fan delivers up to 2.5 hours on low speed, 2 hours on medium and 1.5 hours on high. The 3-watt motor drives blades sized for 44 coverage while the unit stands 2.95 inches tall, making it suited to personal cooling rather than area ventilation. Buyers needing all-day operation without sunlight or higher airflow for larger spaces will find the capacity insufficient.
