This fire hazard is a bunch of iPhone 5C units plugged in and warming up for a September release.
While it’s possible that this is a knock-off, website Engadget says it it seems that the person who posted it does (or did) in fact work at Pegatron’s Shanghai plant. Her name is Sina Weibo, she was part of the company’s quality control department. The above images may be iPhones plugged in as quality control folks test them out to make sure they are fully functional.
We will see it to an official capacity on September 10.
