Is there even a proper full size DC plug standard suitable for residential use? Besides USB I mean, since USB-C is designed for dainty little gadgets, not full blown appliances.

I find most 12V stuff like modems and routers run off a 2.1mm or 2.5mm barrel jack. (And of course it doesn’t imply 12V). You’d need to bodge a double ended connector. Maybe screw terminals would be ideal so you can cut your wall wart cable and wire it up. Most devices will have a bridge diode inside (total waste of electricity, but not going there right now). I guess a cigarette lighter port could make sense but now we might be asking too much on the BoM.

  When I say full-size, I mean a plausible NEMA 5-15 replacement exclusively for DC power; something that you could reasonably run at least a kilowatt or two through, and with a mechanically robust design. It should be able to power a toaster oven or stand mixer, and be mechanically robust enough to survive people tripping over the cable many times and being generally rough with it. Those little barrel jacks are fine for what they are, but I can't imagine powering a toaster oven with one. Cigarette lighter ports might fit the bill, at least mechanically. I haven't seen one of those in many years and forgot about them.

    Really depends on what kind of amperage you want to run through it. A kilowatt at 12V is going to be 85 amps and too hot for something rated for 15 amps. Not sure what’s approved for DC use in general. Standards bodies will probably disagree with using something typically used for AC with DC because of the risk of plugging the wrong thing into it.

    Plenty of options exist in adjacent industries. Stage rigging has a lot of nice stuff for powering lighting/effects (like Neutrik powercon) as does automotive (deutsch dtp or dthd). https://www.neutrik.com/en/products/power/powercon-20-a https://www.neutrik.com/en/products/power/powercon-20-a https://www.te.com/usa-en/products/connectors/automotive-connectors/intersection/deutsch-dthd-connectors.html?tab=pgp-story https://www.te.com/usa-en/products/connectors/automotive-con...

USB-C now supports 240W @ 48V. That's enough to power a full size slow-start fridge.
