I was looking for a flashlight that was waterproof, solar powered, and also had a hand crank. I found such a flashlight made by SolaDyne here on Amazon:

Do you think this is a good flashlight for a medium-sized or larger survival kit?

I have a Duracell brand version in my car pack:

It does not have a solar panel but is crank powered. I like this one because it has a radio and can also charge my cell phone by using the included adapters. I think the two pack ran about $24.

Does not appear to be available through Amazon.com at the moment.

If it's in your pack, but you don't know how to use it...it's useless. So, always test your skills as a form of preparation...Don't wait until your life depends on it. That's a lesson you don't want to learn the hard way.

The Duracell flashlight you mentioned does have a hand crank, but lacked the other features (waterproof and solar power) that I was looking for. And it's available right now on Amazon.
