We always needed a device that is portable to easy to carry anywhere and a Fan With Emergency light that is portable is best choice To buy Jy Super did hard work to make it easy to use easy to charge and easy to carry . they created it with 12v powerful motor and 21 smd light to produce bright light with dual option one for low and for high for both light and fan separate mean if you need only fan then just press fan button and if want emergency light press light button . They also added one 5v jack to charge or use it with solar power .
