Rear camera and USB power in van

[unwashed potato!]

I have the below system in my van

https://amzn.eu/d/aeckXDO

The rear camera worked but the way I had the camera cable running was in the way of some units so I ran it another way, however it meant it was short by about 30cm of reaching the display. I bought a cable, linked below, to extend but it doesn't work. Am I doing something wrong? The camera doesn't power at all.

Is this the right cable? I have never seen a cable this thin be able to provide power, as well as whatever image and audio from the camera.

And then also I'm trying to get rid of the power cable this device comes with and swap to a USBc cable that can go into something like below. The below I bought and this doesn't power the unit at all. I have it into the same cigarette lighter spot as the power cable it came with, but the above does nothing. The reason I want to swap to a different smaller charger is because I want to add USB charging else where in the van, and the unit it comes with is too big

If anyone has an suggestions for usb hubs for vehicles please suggest away.

That looks like an audio cable you linked. I wouldn't expect that to deliver video or very much power, if any

You know what i need in thst case? The cable linked is the correct size but I can't find a video/power version of it

I think at least one of the reviews suggest doing exactly what you are needing it to do.

Thanks I've bought so wills ee of this fixes the issue of the rear camera.

Any thoughts on why the device doesn't power when I use the USB cigerette style devices I linked above?
