Do you want to provide Power over Ethernet (PoE) to an Ethernet device/network? If so, at minimum, the dongle would have to be designed to transmit DC power from whatever power adapter you are using. This seems pretty unlikely if you are using a standard USB-Ethernet adapter, unless it was specifically designed to provide PoE.
Do you want to connect an Ethernet based network to an electrical outlet to be able to utilize the wiring in your house or greater electrical grid to communicate data? If so, the dongle or adapter would need to support Power Line Communication (PLC). Your expectations for data networking over in-house electrical wires or the electrical grid servicing your area, would need to be extremely basic and would require more hardware to connect devices to data being shared from other electrical outlets (or maintain signal over the grid).

Curious to see what the packets are saying from a packet dump.

No, but close! https://en.wikipedia.org/wiki/Power-line_communication
I used this for a couple of years. Worked great.
It kind of depends on what fuse your outlets are on and how your place is wired.
It is a gamble, but when it works, it works great!
we’re currently using powerline as a stopgap until we can get around to running cables in the attic for a couple of our security cameras. we get about 300 megabit! not terrible imho
I hear a temporary solution about to become permanent 😄
oh god i hope not. I have an ibm mainframe chassis in the garage i’m converting into a high temperature rack, and that’s going to need fiber xD
For anyone else that needs it, there’s also stuff for co-ax. Some cable guy went nuts putting coaxial cable into just about every room of my new (very old) house. I seriously considered MoCA for a bit, but wifi is working well enough for the moment.

Depends on what job you want to be done. It would be a perfectly fine solution to make a very subtle light in the dark room, for example.
Power line networking is a thing so why not?
you need to use a crossover cable to get that to work
yes that’s called ethernet-over-powerline
Yes, it will give Power Over Ethernet to whatever PoE device you plug it into.
No. That is an Ethernet to USBC so it’s trying to get data to the power plug. I don’t think it will provide POE
If your goal is to burn your house down, probably.
It shouldn’t; the USB wall plug will provide 5 V which powers the dongle, but it’ll just be idle since there’s no computer communicating with it over USB.
