Inside some dodgy Chinese USB power supplies from Greece.

I'd like to thank Filippos for sending these VERY shady USB chargers which he bought from a Chinese outlet in Greece. The flat one has one of the scariest transformers yet with no extra insulation between the secondary and sense windings. It also had a rather odd output capability of around just 20mA before the voltage plummeted.
