I wanted to share this opinion on Hackaday about a topic that is the usefulness of a something that has become ubiquitous relatively fast.

This techonolgyy has a lot of potential, what do you think?

    Yes, you have 5 V. THen you have outomotive 12 V. But now you would have also automotive 48 V. USB-PD is one standard and can deal with different level of power requirements, from headsets up to laptops. And then you can use for other things as well, in a way that can be more practical than dealing with 110-220 V AC.

    Is it a monstruosity? I don’t know honestly. I trust hackaday in that sense, and they usually praise it, without any hidden reason, I think.

    Also, if you read the article, you can see that it is also a continuation of one from a few years back, before USB_PD was widespread. It touches also the points that you wrote. Give it a read:

      I wouldn’t say usb pd is one standard. There is a combinatorial explosion of devices and cables with different voltage support, current capacity, presence or absence of E-mark and of Thunderbird, the famous incident where a bad cable blew up Benson Huang’s laptop, etc. If you intersect down to the universal standard in the middle, it’s just plain 5 volts like before.

      And are really going to push 240W through that teeny connector and not have any melt?
