I took a look at a few of them. 1 says 5.5 Volts, and the others say 5.0 volts. The all seem to say 1 Amp, and those are all for output, I assume the input doesn't matter. Should I use the 5.0 volt ones, or the 5.5 one? Does it matter? I would assume it does. If I am underpowered, does that just mean it takes longer to charge? If I am over-powered, can I fry something?

Sorry for all the questions...

And thanks for the help so far!
