Wait, @Rocky_H was talking about the UMC which is correct but you added in the "car electronics" which is incorrect. The OP can charge at any amperage he wants without damaging his car.
That's probably true for time under warranty at least (and perhaps beyond for most cars) but I've read posts here about charger failures. They are high wear items, that require liquid cooling. I wonder if this one was charged at 21 amps daily (being 42 over dual chargers) it would have failed:
Tesla Model S Charger - NEEDS REPAIR
Perhaps not? Or maybe it still would have? Regardless, I'd rather spread the amps over two chargers, then pile them all into one. For only $500 for a HPWC I also get to keep the UMC in my car in case needed.
