These are common outlets in the RV and manufactured housing industry.

You can get junctions and switches too. Wire goes through. Position the back side, Use a special tool or a big slip joint pliers and crimp until the latches on the sides catch. With the special tool you don't have to strip wires. Doing it with a pliers it makes it easier if you strip a short section. These make it easy to add outlets.
If you are using a conventional outlet with screws or push-in connections it must be in a plastic or grounded metal box. You can get old work boxes for adding a 120/USB outlet.
I added one of those and several just USB outlets wired directly to 12v. I much prefer the latter. I used a BlueSea outlets. I also got an offshore version that shows voltage at the outlet (sort of handy but not real uaseful) that is a QC2 version, faster charging.
