As a matter of interest how was the fake UK charger connected to the the (presumably US) power supply?
Was any attempt made to separate the effect if any of the socket adaptor from the device performance?

Also looking at the oscilloscope traces I suspect that not only was this tested only for 230V but also only at 50Hz.
