I'm setting up home charging for a Model 3 that will arrive soon. If I set up a Tesla Wall Connector and, in a few years, get a 2nd vehicle that is _not_ Tesla, is there any hope to charge it with the Tesla EVSE? Or, should I look at non-Tesla chargers now? No matter what, I must run a new branch for the charger I'm about to install. To be practical, it must surface mount outdoors (wet location).
