I'm using the UMC at home, plugged into a 30A dryer outlet. Rather than unplug , coil up and put the UMC away in the trunk after each charge, I decided to leave it plugged in and hanging on the wall. It took less than an hour to cut out wood pieces and then glue and screw them together for a handy and secure wall hanger that doesn't bend the cable too much. I used 1/2" plywood for the 12" x 16" backboard and 8" diameter circular face. I cut 12 stand-offs 2 1/2" using 1x2 lumber. I drew pencil lines on the 8" diameter face dividing it into 8 segments. Then I glued and screwed 8 stand-offs around the circumference. Next, I added 4 more stand-offs in the spaces between in the upper half to provide good support for the cable. Next, I mounted the assembly to the backboard, gluing and screwing it together from the back side of the backboard. Finally, I added two 1/2" x 1/2" x 3" retainer tabs using one screw as a pivot to allow them to be swiveled out of the way when removing the cable from the hanger. A small screw on each side and one in the middle serve as a bumpers.
