The charger is supposed to provide isolation, in her case it didn't and her head was literally plugged into a light socket.
Don't think it could be intentionally triggered until they make chargers that communicate two way with the phone "telling the charger" to go into "full lightning" mode.
Now I just realized, most chargers DO negotiate communications before charging starts…
But the charger designers must be in on it.
(made in china alright)
