I find this dubious. I don’t doubt the woman died, but did she die from being electrocuted?
iPhone charger something like 5 Watts (5 volts at 1000 mA).
That might give you a tingle, but it’s not going to kill you...
Unless it somehow wasn’t working properly.. or she tried to unplug the main and the connected to that. But assuming the charger was working dropping the phone on the tub still connected shouldn’t have anywhere near enough to kill.
I am wondering if she had a heart attack or aneurism while in tub with phone and as a result phone wound up in the water. Roommate touches water and gets a tingle and assumed electrocution.
Granted I wouldn’t try this at home, but really See no way if the charger was working properly it’s going to kill you on the output. If it could people would be shocking themselves all the time when they touched their charging cable and it being plugged into the wall but not yet plugged into the phone
1000 mA is 1 amp. Anything over 100 mA can stop the heart. You can feel tingling at 1 mA and at 10 mA your muscles can contract to the point you can't let go of whatever may be killing you.
