Does anyone have any idea if there is a 12V wall socket that has the same mounting size as the USB ports? I have a 2021 Transcend 261BH and it has no 12V sockets, just USB ports. When I took them out to take a look at the wiring, they're barrel shaped on the back like they were intended as some kind of direct fit for what was a 12V socket before. But I haven't been able to find a 12V wall socket with the same screw pattern.

Anybody have an idea of where I might find that? I can work around it if necessary, but a direct fit would be easier and cleaner.
