Yes - a portable charger with the 14-50 will try to draw 32A. (it's max capable). that should pop the breaker. Get a 14-30 plug for your portable charger, or on your car's charging options limit it to 24A. (And check that regularly to be sure the car has not decided to reset itself...) But only as a stop-gap. Get the correct plug and it will limit the charger's draw.
Electrical code says "DO NOT DRAW MORE THAN 80% OF RATED CIRCUIT/BREAKER AS A CONTINUOUS LOAD" As MorrisonHiker says.
I have a Gen2 charger and got a 50A cord 14-50 from Amazon, so I could plug it in instead of hard wiring. But the Gen2 Wall Charger has a dial to set max current limit.
