A difference with the illustrations of the article:
The 2 cables, AC and USB are white.
The transformer is at the end of the cable industry and it is he who carries the 220v input plug.
Final details:
Its color aluminum (slightly lighter than Apple) goes Tinto My Mac.
Cables good measure 1 meter each.
