Earlier quoted context omitted.
That requires the computer to hotswap to be plugged into a power strip. It doesn't work if the computer is plugged into the wall directly. (Well leaving aside modifying the house's electricity / opening up the wall obviously.)
Incorrect. See this video[0] from the product stage. They have two ways to hotswap if it's not plugged into a powerbar: 1) plugging in their device into the adjacent power outlet then removing the socket assembly and 2) an adapter that can splice leads into the power cable https://youtu.be/-G8sEYCOv-o Pretty ingenious, tbh. Though I'm a bit concerned about how much you end up handling energized plugs.
Well that’s what I meant by “opening up the wall”.
