Hmm. My power socket was mounted well above the mounting point for my charging unit, but in an orientation that would have made more sense if it were below the unit. And unfortunately, there wasn't enough room in the box to reorient the socket. But no matter: I had to change out the power cord on the unit anyway, because it (a United Chargers Grizzl-E) isn't available with a 14-30 plug, and I saw problems in putting a 14-50 socket on a 30A circuit. And the 14-30 dryer cord I installed on the Grizzl-E was plenty long enough and flexible enough to make a 180 degree turn above the power socket.
It should also be possible to find parts at your local Home Depot, Lowe's, Do-It Center, or similar establishment, that will allow you to build a short extension cord that would correct the orientation problem.
To see a set of pictures of my installation, go to the "Testimonials" page on the manufacturer's site (https://grizzl-e.com/testimonials/), and it will be in the testimonial from "James Lampert," with the upper right picture clearly showing where the charging unit is plugged in.
