I have 6 chargers and I know a few that I have owned in the past have been counterfeit. I'm trying to weed any I have that are out. Of the 6 I have 2 are "green dot" (with serial no.'s) and 4 are "Apple Logo". I weighed them and the green dots are 23g and the logo ones are 25g. Here is a pic: http://i.imgur.com/tYch752.jpg QUESTION ONE: Any help on telling if these are legit? QUESTIONS TWO: If it's true that counterfeit 'bricks' can damage the iPhone, what damage do they cause and how?
