There is a reason for USB-C extensions not to be part of the standard. They can be bothersome in the best case and dangerous in the worst.

    Chaining regular extension cords isn’t a problem by itself, connecting too many things in parallel and exceeding the rated max is a problem (and chaining extension cords “just” increase the risk that ordinary people will decide to connect more than they should, especially because the lowest rated cable in the chain sets the total limit)

      The issue of chaining extension cords is that you can physically plug a 10 amp extension cord into a 30 amp cord. If you don’t know what amps the device will pull, the 10 amp cord can overheat.

      It’s an almost identical problem to USB c.

        That’s just rephrasing what I said. You can plug in too much for a single extension cord even if there’s no chaining. A chain “just” increase the risk.

          Yes but I was emphasizing the parallels to the USB c problem.

          In USBC if you use a 200 watt cable that has 200 watts going through it and then extend it with a 15 watt USB c cable, the 15 watt cable will over heat.

          If you plug a 30 amp load into a 30 amp cable and then extend it with a 15 amp extension cord, you will get overheating on the 15 amp extension.

        You could also just plug in the 10 amp cord and plug the device into it. The chaining doesn’t change anything here.

        I feel one would have to work really hard, with really shitty extensions, with really high amp draws to cause a problem.
