In this video I’m examining and repairing my faulty USB phone charger (5V 1A switching power supply). It failed after 2 years of seldom use. I’ve drawn a partial schematic in the video. Full reverse engineered schematic of this charger is here:

WARNING:
Mains voltage is dangerous! Risk of electric shock and death. Risk of fire. Leave repairs to professionals. You do everything at your own risk. This video is not an instruction (this is just my vlog).

My problem is
In different mobile charger same voltage but different current , means there same 5 voltage d.c but there different current value ,
Like 0.5 mA ,0.7 mA ,1 ,1.5 mA .
How does it done in a charger.

Andy Tipping says:

fair play mate – enjoyed that

Benjamin Esposti says:

I think the 6Z2 chip is actually a dual common anode zener diode.
As for the emitter of the switching transistor – it probably connects to the chip because the chip has an internal current sensing resistor or something like that, for overcurrent/overpower protection.
