USB-C PD: New Technology Done Right
hackaday.com
There is a tendency as we get older, to retreat into an instinctive suspicion of anything new or associated with young people. All of us will know older people who have fallen down this rabbit hole…

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?
