This is very new to me. I'm a little confused on how to get started using it. . I just purchased a Droid and am already liking it a lot better than my BlackBerry. Like anything new, it takes time to figure out. I just purchase a xpal 2000 power charger. It is a 5 volt charger. I don't know if I can safely charge the 3.5 volt battery in the Droid.
