I would expect that every J1772 opportunity charge cord ("adapter") provided by
a vehicle OEM will be UL listed and is clearly approved by that vehicle OEM for
use with their vehicle(s).

This sort of adapter would be used by a non-OEM EV to charge *from* a J1772
EVSE (such as a public Level 2 charging station). A J1772-compliant EV will
not charge unless the EVSE/adapter provides a valid pilot signal, however, a
J1772-compliant EVSE (charging station) *will* provide AC to a non-J1772
compliant EV/charger as long as the adapter loads the EVSE pilot signal
appropriately.
Cheers,
Roger.
