So it is that the reports of the death by electrocution last week of a 23-year-old Chinese stewardess, apparently by way of a faulty third-party iPhone charger, were followed Friday by reports of a second Chinese iPhone electrocution — again via third-party charger and a wall socket of uncertain grounding.

According to the second story — reported Thursday by the 
Beijing Evening News
and picked up by outlets from AppleInsider to Morning Joe — 30-year-old Wu Jian Tong was plugging his iPhone 4 into the wall when he shouted (in Chinese) “I’m getting shocked,” stopped breathing and had to be rushed to the hospital, where he was still comatose 10 days later.

If there’s a lesson here — beyond the rules of second-day journalism — it’s that using knock-off iPhone chargers carries risks, especially in countries where you’re not always sure the electrical wiring is up to code.

For background on what separates a good charger from a bad, I recommend Ken Shirriff’s primers:
