I was in an apple store earlier today purchasing an iPad 12W charger for my iPhone 6 plus. I overheard an employee telling a customer that it would damage their iPhone if they charged it with an iPad charger. She said to the customer that the iPad charger was meant for an iPhone and that the iPhone's battery wouldnt last as long in the long run. I later told the customer that its fine to use an iPad charger and that would it just charge his iPhone faster. I am doubting myself now. Just wondering what everybody else thinks about this? I havent opened my newly purchased iPad charger, but, have been using my charger that came if with iPad air with my 6 plus for a few days now.
