Aiming for the max (V3 = USB-C Socket)

With USB-A and 5V, the max charging current seems to be 1A. With USB-C and 5V it seems that 1,5A are possible. So lets do another (last?) version.

At least according to this source - higher currenty on USB-C with 5V should be easy. According to the headline, up to 3A should be working.

I ordered two USB-C sockets which I found out without even trying, that these small pins will not become friends of my loose-in-the-air resistor cabling.

Oh, there are pretty nice small boards with soldered USB-C sockets availabel as well. Let’s order these and wait again.

When the mini boards arrived, I just had to adjust the 3D model again, making it a nice housing for the small board instead.

Putting it together

Result

Measurements done on the laboratory power supply show that my Galaxy S21 draws around 1,5A from the socket when connected to 5V. Not quite the 3A that seem to be possible as well, but better than the 1A from previous model.
