Shaving off the Neutral pin from the NEMA 14-50 adapter in the mobile kit means that adapter would fit both NEMA 14-50 (50 AMP, stove) and NEMA 14-30 (30 AMP, driver) receptacles, should you come across either. Knowing the adapter is rated for the higher 14-50, it would easily handle the 14-30. You can adjust the charge rate on the touchscreen, so jack it down to 30 when you know you're plugged into the dryer outlet, jack it up to 50 if you're in a stove outlet. Anybody done this? Or maybe you can answer these questions, is there logic inside the adapter that: a) informs the mobile kit what adapter is fitted? b) senses for Neutral, faults if not present? If the kit needs to have Neutral present, then it would also be possible to not shave the Neutral pin off completely, but grind it "in half" (split lengthways) to fit both NEMA 14-30 and 14-50 receptacles (see pictures in wikipedia search "nema" to see what is meant). Anybody tried that? It would be a lot easier to take the pin off completely, if Neutral is not needed (sensed) by the mobile kit.
