I guess I'd need to know what setting the charger was set to. The early Tesla chargers that went up to 80 amps smoked a couple of my installs. The newer ones have been ok. I don't care for the idea of the latest gen Tesla ones need you to connect to wifi to adjust the charger output. The previous ones had switching for it that I remember. What I really hate is skimpy to no documentation delivered with products and all you get is one of those codes to scan or a link. Don't they realize even in affluent areas, there isn't always wifi or cell service available. The lousy pictograms and poorly translated text is crap.
