From what I know, AC let go current at 60 Hz triggers at a smaller amperage than DC, making it more dangerous at the same voltage.
Not quite sure what you mean by that, but I'm not a doctor, and it's quite possible that the AC, if you don't (or can't) let go actually ends up being more likely to stop your heart. In any case, like you said, either is quite capable of killing you.
She may have touch outlet but no way you can get electrocuted from charger that is plastic .
I don't think AC or DC has any think to do with it .You can get electrocuted from both.
You're correct that you can get electrocuted by AC or DC, but like many in this thread have said, there are a number of ways in which a faulty charger, possibly coupled with bad house wiring, could have fed 220V AC to the conductive outside case of the iPhone through the ground line of the charging cable. That the outside case of the charger is plastic is completely irrelevant--it has wires coming out of it going to the phone, which itself has a conductive outer case.
What you're saying is like saying you can't get electrocuted by your toaster because the power cord is coated in rubber.
.... and this. Apple will regret throwing suppliers under the bus
What on earth does Apple inspecting Foxconn factories for safe labor practices have with someone who bought a knockoff charger (no doubt not made by Foxconn) in China? (Probably bought from a fake Apple store selling counterfeit Apple accessories at a huge markup.)
It's utterly and completely irrelevant, unless you're implying that Foxconn--one of the largest manufacturing companies on earth--has a James Bond villain evil scheme to dump dangerous knockoff iPhone chargers on the Chinese market hoping that they will electrocute some people and give their
largest customer a bad name. I mean, it's not like they might, you know, get CAUGHT when somebody investigated the deaths and figured out where the faulty chargers came from, which could result in their being punished by the Chinese government (which has been known to execute people for dangerous consumer practices), and would most certainly make Apple, their largest customer, really, really angry.
