More on those cheap chargers / adapters. A few months ago, one apparently electrocuted a woman, in Australia:

They're of the same "flavor", as those that exploded in the original video. From past experience, I know the max output is pure fiction. With a 22 ohm power resistor as a dummy load, the voltage already dropped to 8.5V (385mA). This probably means that I'm already stressing the unit. I suspect the true max rating should be ~250mA. What I'm using it on, draws 35mA. It usually is powered off a battery. I'm never leaving this thing plugged in, unattended. Maybe I should build an insulated steel test box. I need one for thermal tests anyways. Put a powered supply inside, under various loads, and see when it burns up.
