The Fenix E-Star is a portable flashlight designed for emergency situations where power might not be available. The light can be powered by the included low-discharge Ni-MH battery, or one AA battery, or by pumping the charging handle when the battery is low or not available. It uses USB Type-C charging and the built-in super-capacitor helps with energy storage and buffering when the battery is damaged or missing. The E-STAR has four output modes with a maximum lumen output of 100 Lumens and beam visibility of 131 ft. This is a great light to keep on hand in your emergency preparedness kit - in the house or in the car!
