Using this Tesla to J1772 adaptor to charge a Bolt with the regular Tesla charger is more kw than a standard L2 J1772 correct? (9kw I believe rather than 6kw)
So the adapter is only useful if there is no J1772 L2 or CCS around?Nope, charging is the lower of either EVSE or car. The Bolt is limited to 32A, so 7.2 kW @240V.
Having it would open a large number of free charging locations but realistically the $200 to buy it would almost never break even.The adapter allows you to use the versatile Tesla Gen II EVSE. You can also use it on Tesla destination chargers. If you don't own a Tesla Gen II EVSE, and don't intend to use a Tesla destination charger in a pinch, it is of no use.
