I think i already know the answer to this one but thought I'd ask an expert here. We have two iPhone chargers in the house and I recently started using one of them. Upon plugging it in I've noticed there is an ever so slight buzzing noise when charging. It is now unplugged and no longer in use! (Click to enlarge) The lighter one of the two is the one I know is official whilst the darker one on the right is my suspected fake. They look identical on design but the darker one had different information printed on it in a different style. Official: Model no: A1399 Lighter plastic Slightly heavier. Suspected fake: Model no: A1299 Darker plastic Slightly lighter Buzzing noise. Am I right in thinking I have a fake accessory in my midst? I found it unused in a drawer at home and had no idea where it has come from. Thanks!
