'Fake' iPhone charger cited in electrocution death probe
New details reveal victim may have been using an unauthorised charger for her iPhone 4
A woman killed by an electric shock while using her iPhone may have been using a non-Apple-made battery charger at the time of her death, Chinese state media reported.
“Knockoff chargers sometimes cut corners,” Xiang said. “The quality of the capacitor and circuit protector may not be good, and this may lead to the capacitor breaking down and sending 220 volts of electricity directly into the cell phone battery.”
Another possibility was the charger had been intended for use in Hong Kong, Taiwan or Japan, Xiang said.
“Hong Kong, Taiwan and Japan all use an electrical voltage of 110 volts,” Xiang said. “Mainland China uses 220 volts. If the charger was made to accommodate only 110 volts, then it’s possible it may have broken down and [overloaded.]”
Xiang's comments are not entirely accurate - Hong Kong has a standard electrical voltage of 220, although 120 voltage outlets are found in some hotels. Japan has a standard voltage of 100 volts.
Xiang said that normally, the electric current from an overloaded charger would overheat the phone’s casing, damaging the circuits inside and rendering the device unusable. In the case of Ma’s iPhone 4, however, authorities said the phone could still be started normally despite severe traces of burning on its exterior. The phone’s data cable, charger, and plug were all intact.
A police investigation is underway. A spokeswoman for Apple said the company was “deeply saddened to learn of this tragic incident and…will fully investigate and co-operate with authorities in this matter”.
