AFAIK, there aren't any. There isn't any standard for voltage. There isn't much demand or advantage for DC in the home. There might be slight efficiency gain but have to replace all of your appliances. Appliances which don't exist.
There are a bunch of DC power connectors but they are mainly for connecting cables and for low voltage. Powerpole is my favorite since genderless and maintains polarity, but can pull out.
Boats, RVs, and off grid homes mostly use 12V DC. There are some that are using 48V for efficiency and higher power appliances. My understanding is that everything is hardwired. Lots have inverters and AC plugs.
- mixmastamyk 3y agoI exempted kitchen appliances, and suppose laundry too. Sometimes these are on 220 which is a different circuit already, right? Everything else in our place needs to be converted to DC. Edit: can't reply, so added below: Our lighting has been LED for a decade. USB PD up to 240W handles most of the other issues you mention. I have a USB Fan at my desk. I think the issues are solvable if one is motivated. ;-)
- ianburrell 3y agoWhy? Which DC voltage? The low voltage that use now is too low voltage for running in the walls. You're going to need converter boxes; DC-DC converters are more efficient but you are going to have wall warts everywhere. Also, USB-C is not enough power for things like TVs. Plus, I have a bunch of things like fans and lamps that need AC. So now going to have converter boxes from AC toDC. Also, appliances are where all the efficiency gains are because that is where all the power goes.
- Dylan16807 3y agoNormal AC power for LED lights means you have big capacitors getting very hot and that dimming is very difficult. It's not a good way to do it.
