True. However, where I live, there are a number of lodges and B&B's in the northern West Virginia highlands and ski areas that provide free L2 charging for people coming there in EV's - but they only have standard Tesla chargers. This is logical, because until a few months ago, the Tesla is the only car with the range to cross the charging deserts between those places from the DC area or Pittsburgh. So if you are an early adopter of a Chevy Bolt (I think they just became available in Maryland?) this adapter might be useful - but that's the only situation I can think of.Most of Teslas public charging networks are superchargers, which this thing doesnt support. It only works with the wallboxes for home or office installations, so it's not likely to be very useful for anyone who doesn't also have a tesla.
