I ordered several USB-C connectors from AliExpress with just four solder pads on it. I will only use these for powering and not data transfer btw.
This is the connectors i ordered:
I have read that USB-C is good for up to 20V and 5 amp and i just wonder if i need to use all four solder pads or just "V" and "G" (ground)?
Do i have to use the two in the middle D+ and D- ?
Powering what?
If it is a computer then I don’t think it will like 20V.
If not it is a bit dangerous as it might get accidentally plugged into one.
You don’t have to make use of the D+ & D- lines, but if you do it makes a better connection with less contact resistance at the plug / socket interface. But it also increases the danger if the lead is ever misused.

It is vastly more complicated than that.
You need to read up on how USB-C works!

If you are only going to use as a power connector with no data I would double up on the pins. Normally I buy a connector based on the intended application. I haven't a clue the current handling capacity of those connectors you posted. Anyway I would double up since it takes no effort of any amount. Then too, that would not be my connector of choice for 20 V 5 A.

If you examine that image, it would appear that all power pins are in fact, paralleled.
What puzzles me is that there are only seven connections per side, whereas USB-C defines 12 actual pins per side.
20 V/ 5 A - or indeed anything above 5 V, only happens if there is a chip in the connector.
