Jonhon's charging adapters are equipped with multiple safety features. Over - voltage protection ensures that the adapter can handle sudden voltage surges without damaging the vehicle's battery or electrical system. Over - current protection limits the current flow in case of a short - circuit or abnormal load, preventing overheating and potential fire hazards. Reverse - polarity protection safeguards against incorrect connection of the charger to the vehicle, which could otherwise cause serious damage. The adapters also have insulated housings and reinforced connectors to prevent electric shock and ensure safe handling. These safety features provide peace of mind for EV users when using charging adapters.
