It's for solar power to various devices for "camping" The circuit for the cell phone is right at the end. I would want to run it off a hub. Anyone know what one would need to do for that?

I've seen a company called Voltaic that makes ready to go stuff that (if you have it charge the phone directly, and not charge a battery first) start at about $35.

I can vouch for Voltaic's awesomeness. Husband got me the 4W charger and the V39 battery pack. Worth the dosh, it's tough and efficient. I start the battery on a full charge from a wall socket and then let it trickle charge from the solar panels all day, tapping the battery when I need to for my iThingies. Also charges Knog USB lights nicely.
