Piggyback Usb Socket

[T6 Owl]

Hi all,
I am wanting to add an extra USB socket to power my dash cam. I don’t want to use the existing sockets as they are all permanent live and I also want to hide it away.
I want to piggyback a socket from a switched live fuse.
I have found this on eBay and wondered if it would be suitable?

Thanks in advance.

Brilliant thanks for that Dell, top info.
Just to confirm, the black wire from the usb socket is the ground?
Also, what fuse size would you recommend for powering the dash cam?
Thanks again

The black out of a red/black is normally ground..

And 5a fuse for a dashcam.
