Eh, I'd spend $10 more and get something like this with a built-in radio and crank/wall charging/solar charging/AA battery charging capabilities. It's a few dollars more for a lot more flexibility and functionality.

Between that, an 18650 headlamp, a solar-chargeable LED lantern, I've got reliable electronic light for months.

Ultimately it's up to what you think you need. Something like that hand-crank flashlight may be a good backup light source for a get home bag ... but I think there are better options for a multi-day bugout, especially if you need to keep on the move as much as possible.
