I have an EV that I've been charging from 110 because it works fine for overnight usage, but I've wanted to charge it from 240v as well for faster turnaround. I bought a 240v J1772 adapter a while back when it was on sale, but I haven't installed 240v in the garage yet. Now that I've placed an order for a Tesla I'm trying to decide the best option for charging the Tesla and also being useful for charging the existing EV faster. Also, I want to avoid doing too much work on this place because I don't own it and don't want to put too much money into improvements on a place I don't own and who knows how long I'll be here. The owner is not interested in doing the upgrades, but is OK with me running new lines to the garage on my own dime, though. Option 1: Install a 14-50 outlet, either plug in the Clipper Creek for the older EV or the UMC for the Tesla, Tesla is limited to 40A. I have to pack/unpack the UMC to charge the Tesla and also have it for emergency use on the road. Option 2: Install a 14-50 outlet and a wall connector that draws as many amps as my panel can support to the garage wall. I can charge either at best rate, but I have to watch and not charge both at the same time. Cleanest install with fewer devices being juggled. Harder to remove the wall connector when I move, though. Option 3: Install a 14-50 and modify a wall connector to take power from the 14-50. It looks like the design of the housing of the wall connector isn't designed for this, but it would make it easy to take the wall connector with me for future use. The wall connector would be limited to 40A as well in this configuration, but overall the solution is cleaner than using the UMC all the time. Option 4: Install a 14-50 and buy a second UMC. Not quite as clean feeling as having a wall connector, but saves having to pack and unpack it for every use or road trip and easiest to uninstall and take with me. Option 5: Install a hard-wired wall connector and continue to live with 110 charging for the other EV (which only has a 10kwh battery, so that is livable). Not sure how hard it would be to remove and take with me when/if I move, though. What's unclear to me is how hard it would be to "undo" a wall connector hard-wired connection and leave no/few marks if I take it with me. Also, if it is feasible to modify the wall connector to use a 14-50 outlet...?
