Has anyone had any experience with solar cell chargers? I saw one on a deal of the day site -dealblade.com - simultalk iPhone charger for $47- Is that a good deal? Do you like yours?
thnx

Ive got a Scosche Solbat II

I like it, it gives me about a 75% charge when my phone is completely drained. Really small and portable, ability to charge via USB or through solar, but a full solar charge can take up to 4 days in direct sunlight.
