HydroStar SUB Flashlight

Put that overworked right arm to some good use with the HydroStar SUB Flashlight. Incredibly useful in a jam, you'll never need to rely on batteries again with self-cranking power. It can even charge your cell phone or iPod if you're stuck without a charger, which obviously is the real emergency. The perfect worse case flashlight, it's waterproof, has four modes of light, including a power saver mode and is very durable.Source
