There are cheaper ones as well with a single output voltage. Use the highest output voltage that can still be accepted by your dc dc converter.

What module you use for usb C charge ?

Thanks for sharing your make! Glad you like it so far.

Finally my first bench power supply!
The case fits my cheap dc buck converter perfectly.
Keeping my fingers crossed, that the hot glued USB-C connector board doesn't come loose.

Anyway, I think it looks great on my table, doesn't take up much space and just works! Thank you so much for sharing!
