hello,
I am wondering does anyone have any idea how to have the smallest charging station as possible from an AC circuit directly to a micro USB port for a phone PCB?

Use a USB phone charger. Apple charger are about a cubic inch.
hi dennis
im more after a power convertor which would be directly placed in between the wiring of the 240v and the device.
if I could draw it with a keyboard something like this
=wiring "convertor" +device+

That describes a standard 240V mains powered USB phone charger, does it not?

You will not be able to make anything smaller than a bought switch mode power supply. You could make one the same size but you would have to design the transformer and find a manufacturer to produce it. They would probably only be interested in manufacturing if ordered by the thousand or more.
