Today I made a teardown of a USB charger donated by one of my viewers and I reverse engineered its schematic. Then I found that the transformer in it has no isolation between the windings! This USB charger from China (fake Apple iPhone charger) has a transformer with no insulation tape between the primary and secondary side. The output of it (and thus the entire phone including its metal casing) is isolated from mains just by a super thin layer of enamel (lacquer) on the magnet wire! This means a very high risk of an electric shock and death. This dangerous electrocution device comes in various colors including white, which looks just like a real Apple iPhone charger.
