I know about the problems with the first Banggood power supply that was copied from an old Greek kit but I do not know about this one.

Not much in the way of active devices for a PSU with voltage and current control. I wonder if they are doing something really nasty and handling the actual regulation within the micro?

I suspect it to be a variation of the
