I'm sure I must be missing something, but...:
Is there any reason I can't build & use a hard-wired cable with a NEMA 5-20p plug on one end & a J1772 on the other, plugging the 5-20 into a L1 20A source & the J1772 into the Tesla adapter thence the car?
AIUI, there's some circuitry involved for the cord to tell the car "hey, you can draw up to 16A [in this case] and no more!" Can that be duplicated without the Mobile Connector magic? How does your average L2 J1772 charging spot do it?
Why? I'm probably going to be parking somewhere with limited power--i.e., the 20A outlet I'm considering. I'd like something less unwieldy than the Mobile Connector, and less tempting to a light-fingered thief. A basic "extension cord," fitted to connect to a 20A wall outlet on one end & an EV J1772 receptacle (Tesla adapter, in this case) on the other would seem to fit the bill....
