Dangerous USB chargers 17 (QC 3.0 with schematic)

Yet another pair of questionable USB phone chargers. They don't comply with safety regulations, they can cause an electric shock, fire or electromagnetic interference (EMI). One is a Quick Charge 3.0 charger rated 5V/3A, 9V/2A, 12V/1.6A (not really), the other is a small 5V/1A charger (again a fake current rating). Let's test them, see what's inside and how do they work, including the schematic of the fast charger.
