The barrel pin system could have been great if it was standardized. Only one valid polarity with barrel size being keyed to voltage while pin size was keyed to amperage, for example. A plug would only fit if it was the correct specs, and would always fit if it was the correct specs. Unfortunately, nobody ever had this idea while they were popular and it’s much too late now.
