I love that it has a standard RJ45 ethernet connector.

I thought I saw an HDMI connector, but maybe I was wrong.

Ha! Reading this comment made me curious, so I went back and looked at the article and there does seem to be a full sized HDMI connector. I wonder if it is enabled, or just for Tesla internal testing?

It's only a debug port and not actually HDMI signaling, unfortunately.

How many PoE adapters would it take to charge a Tesla?

Mostly depends on how fast you want to charge.
