I just received delivery on my 2023 MYLR and have a NEMA 14-50/240 v outlet with a 50 amp breaker. My electrician told me I can charge at 40amp but is worried about 50 amp, and of course the current TESLA OEM mobile charger delivers at 32amps. There are 40amp mobile or “portable” chargers on the market and I want to charge at a higher because I will be traveling with a camper/trailer (2100lbs) and would like to charge at a faster rate than 32amps. Does anyone have an opinion if there are “safe” 40amp mobile chargers for the MYLR? Why does TESLA only have 32amp mobile chargers and not have higher amp chargers on their Store website? The TESLA wall mount charger is 48amps but is not portable.
