I was at Costco today and picked a pair of crank flashlights for 15 bucks. To my surprise, they are really bright! They played for about an hour and I didn't notice any change in brightness. And also have AM/FM/Weather. It also has a USB out so it can be used to charge a cel phone (at least in theory).

My girls had a blast playing with them tonight before bed. They look forward to taking them on our next camping trip.
