I think this may be the first time I've found one of the little transformers in these supplies with the windings straight on the top of each other. So the only thing between you and the mains is the lacquer on two tightly wrapped bits of thin copper wire.

I clearly have to take more of the transformers in these things to bits.

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.
