Never have the problem of having your microlight run out of juice just when you need it, whether in an emergency from long storage or in the middle of a long night of clubbing from overuse. This small 2-LED white light recharges with just a few cranks of the retractable handle. The LEDs are very bright too, not like the dim light provided by many similar crank-charged lights. This is also a great item to give to those you love for emergencies. No need to worry the batteries have depleted from storage when it comes time to use the light. Compact size- just 1.25" wide x 1.5" long x 0.5" thick. Throw one in your car glovebox, leave one in your purse, and carry one with your keys.
