I'd have a fire extinguisher rated to put out electrical fires nearby in case someone still decides to disconnect your EVSE, not pay attention to the warning sign, and plug in a 120v appliance. I'd do this because it's electrically safe so long as nobody ever tries to plug a 120v device into it, and it's the cheapest since the only expense is a $3 receptacle. I'd get a single receptacle instead of dual just to minimize the temptation to plug anything else in.

Well I finally got around to doing your suggestion. I also wrote in a sharpie all over the plate not to use for anything but car charger and 240 V. Nobody else around here usually messes with anything and there is an open regular 120 dual outlet 2 feet down the wall so I think that will be safe.
First try it had said 2 hr 40 mins to charge on the 120v. Plugged it in to the 240 and it says 1 hr 5 mins so it's more than twice as fast. Well worth the $5 this cost.
Although now I'm thinking about getting a real EV and if I do I'll add a new 50 Amp 240 breaker with it's own dedicated new wiring probably just in surface mounted conduit. I was looking at the Lightning (put a $100 order deposit actually) an think I'd just stick with the standard range which comes with a 32 amp level 2 charger. If you spring for the extended range you get an 80 amp dual charger but I'm not sure how that's wired at the wall. I know it has 2 charge cables from there to plug in to both side of the truck at the same time. So I assume that needs a 100 amp breaker.
Oh and they issued a recall on the rear hatch programming so someday I'll take it in for that. It still sometimes doesn't "start" and has to be turned off and back on to go into gear.
