Note that many of the pictures don't include all the insulation. (I mention this in Footnote 5, so it's easy to miss.) In particular, there was a black plastic insulator over the USB output plug that only appears in the first picture. And there are several layers of insulating tape around the transformer. This should meet the safety standards; if it didn't, they wouldn't approve it after all.
