What is the advantage of HPWC vs J1772 80A power connection, or are they compatible?
Will the HPWC work with non-Teslas?
Does the Model S charge differently with HPWC vs J1772?
Not compatible. No non-Teslas on HPWC. Hi amp J1772s will charge the same as HPWCs. The HPWC plugs in directly to the MS without adapter. Some install them at home for the convenience (even without having twin chargers), no UMC needed, so it can be left in the trunk for road travel.
