If it's only 6 days you need coverage for then you might want to consider a portable charger instead. It's basically a battery pack with a USB interface and they come in a lot of shapes and sizes. It would be a lot faster and more reliable than solar, but it too will run out after a few charges so they're only practical for a week or two. Just search Amazon for "portable battery charger" and you'll see a gazillion of them.
That's actually a good idea, I didn't think of it.
If I fully charge one of those units, and leave it OFF until needed, how long do you think it'll hold a charge?
For example, I charge it. 4 days into the woods I need it, turn it on. Do you think it'll still have juice on it?
