Comment on USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!

  Thank you. Also I could have written it better. Reading what I wrote again I wasn’t happy at all. It really sounded a bit fake…

    you wrote it? Cool!

    I’ve really been loving USB PD, and retrofit into several devices i use. My big next interest is the USB PPS, allowing devices to request extermly minute adjustments to the voltage, instead of just “9v”

      No, I only wrote the intro of this Lemmy thread. It’s the part that @rusticus@lemm.ee said was AI generated. At least that was my understanding.

      I really hope that the hackaday article cannot be confused with ai generated garbage… Or maybe my taste is really bad!

      A question because I don’t really understand:

      Does those “really minute” voltage adjustments really matter for the vast majority of things you can use USB PPS for? I’m sure there are some devices out there that do, but I would think most don’t care too much if the power is 9VDC or even 6VDC or 12VDC for brief periods. Perhaps the slightly increased lifespan might matter or not.

        Yea, i do think it will help, primarily with battery charging.

        Right now, in order to protect the battery, the phone will request 9v, then step it down as the battery charges, and send a reduced voltage to the battery, so over time the battery might see 9v… 8.95vm 8.9v, 8.85v…

        This allows the step down to happen at the charger, instead of in the phone, increasing efficiency, and reducing heat in the phone.
