The newest of the Sunbender DIY solar kits, the Sunbender USB with Digital Meter is the perfect kit to learn about solar energy and build something you can really use. Includes everything you need except 4 AA NiMH batteries. Includes a high output USB board that can charge even the "power hungry" phones like the iPhone 5 (does not include phone!). As long as you have enough power in your AA's from solar charging, this charger will charge your smartphone as fast as if it was plugged into the wall outlet. This do it yourself solar kit requires basic soldering skills and basic construction assembly skills.
