does anyone have any experience with solar chargers? I spend alot of time outdoors an would like to find one that works good. i read one post about this, but i was wondering if anyone else had any recomendations. I would like to be able to spend a week out and use only a solar charger to keep me up and going. i'm currently using a commando and it would be kinda silly to have phone, gps, camera etc... when this one device could do it all. thanks for the help. Ton Bon.
