12V plugs to replace USB

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.

I'm doing the same do we can run our CPAPs when we are boondocking.

It only has 12V input. There is a white one on Amazon the shows the back, dimensions, and the wire.

You will need to open the hole up a little more though. It's a standard outlet size.

Yep, that's my backup plan if I can't find what used to be used in these trailers before GD switched it to USB. As you say, just need to make the hole a little bigger.

Well, considering you will not be using the USB ports (neither will we), I don't think it's going to be that big of a deal.

The irony is that most of the time I will be using USB ports, just better ones than the terrible little 1.2A ports that come from GD. Those won't even charge my kids' iPad minis. Heck, one of the ports next to the bunks was nonfunctional when we got the trailer, and the other port was really loose (but did charge my phone). So that socket will just get a decent dual port USB charger stuck into it that can flow enough power to charge an iPad. The one up in the bedroom is slightly more complicated, because I want to charge my phone, watch, and run the CPAP. Though the low power USB ports on the Magnadyne are probably sufficient for my phone and watch.
 
One other thing to consider, make sure the wire that is feeding the existing USB port is going to be larger enough to handle the load that you will be putting on the new socket. I have no idea what size wire they use for those, but it certainly needs to be considered.

Since this is in the bedroom, I'm just going to use the existing wire to pull (okay, try to) 12 GA wire for the socket. For that run, 12 GA is enough for both the CPAPs. I've done my calculations on that already. I REALLY don't want to wake up to a fire.

Good to hear you are on top of it....and I agree, no reason to cause a safety concern with wire that's too small for the load!

I haven't measured the actual conductor size yet, but the wiring harness looks like it's probably 12 gauge. Considerably larger than the cute little leads going to the USB port itself. It's the same wiring driving the radio, which is spec'd at 10A. That's more than enough for any of the adapters I'll be using, even the CPAP only pulls 7 amps. Beyond that, I'll just have to assume that the fuse in the panel is sized correctly to protect the wiring.

Hopefully the fuse prevents that scenario :).
