I've pretty much made up my mind to buy a Prius Prime plug-in early next year, either as my only *EV for a while or in addition to an M3 when my reservation comes up. So for now I'll need a J1772 charging solution. I'd like to future-proof my charging needs, and if not too expensive, install a charging station for courtesy use for Tesla and other EVs in addition to my J1772 charging requirements. Can a Tesla Wall charger fill these duties ? I realize that an alternative is to install an L2 40A J1772 solution and let Tesla owners attach an adapter.
