For my iPhone and iPad --
I'm getting conflicting reports from friends who have tried to find a good one.
Ideally I'd like to be able to put out the charger in the morning, have it collect the sun's rays all day, make and store electricity, and allow me to fully recharge my iPad or iPhone from "just about empty."
Also it would be great if the solar collector is waterproof so I didn't have to worry about getting it out of the rain.
Any DLers know of a great waterproof solar charger?
