We use this as an extension for the Tesla mobile charging cable and it works well for that purpose. On a 50A circuit with a Tesla mobile charger, we can draw 38A (= 30 mph charge per Model Y). Neither this cable nor the mobile charger gets very hot. It's heavy, bulky, and not exactly cheap, but it does its job well and securely.
