I bought a Suntactics solar charger back in 2010 and have never regretted it. It's a charger only - no battery. It's only 1 amp (5vdc) via USB and it charges my small electronics (iPod, Kindle, smart phone) at about the same speed as using their respective AC cords, and, since it has a USB plug, it works for all three. I've never gotten mine wet, but it advertised as being waterproof.
