Solar Power Backpacks

These voltaic backpacks are great for hiking because you can be charging up your gear while you hike.  Most of these backpacks come with a battery and you can charge up that batter to use for power later as you travel.  Some of these solar backpacks even come with adapters so you can power any electrical gear you may have taken with you.  These are very popular right now as solar power becomes the way to go.  Oh, and of course they are backpacks too so you can still store all your stuff you need inside.  But if you are hiking in the sun, you might as well use it's energy to power your stuff as well.
