Kevin McCoy, USA Today:

The knockoff power adapters and chargers, which Apple says could cause electrical shocks, allegedly traveled from a manufacturer in Hong Kong to Amazon.com, with stopping points at the Brooklyn location and New Jersey electronics companies.

And:

From outward appearances, the Apple-like products seemed genuine.

However, the chargers and adapters lacked adequate insulation and had improper spacing between the high voltage and low voltage circuits, creating risks of overheating, fire or electrical shocks, Apple charged in a 2016 federal court lawsuit. The case ended with confidential settlements in late May.

And:

Twelve of 400 fake iPhone adapters tested in a study unrelated to those in Apple’s lawsuit were so badly constructed that they posed “a risk of lethal electrocution to the user,” U.S.-based safety standards leader UL warned.

When I first came across this article, I was pretty sure Amazon would be part of the equation. In addition to the obvious safety hazard issues, I also wonder if there are some counterfeits with embedded malware, just waiting for an unsuspecting device to be plugged in. One reason I zealously guard the USB bricks that come in the iPhone and Apple Watch boxes.
