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

  Do you have an source on that? I planned to get one soon and that's worrying. So far I've found this post after a quick search, which claims PD is supported.

    Maybe he’s talking about the pi 4, which did have usb-c power issues on its first revision. bgr.com/…/raspberry-pi-4-usb-c-charging-issue-how…

      The Pi 5 wants 5A and 5V, which I believe [citation needed] isn’t supported by USB-PD:

        This article about usb-pd lists 5v 5A as an available option howtogeek.com/…/what-is-usb-power-delivery-usb-pd…

        USB PD never exceeds 5A of current, but the voltage can be dynamically configured to meet the needs of a device up to the maximum power limit for the standard.

        And

        When a USB PD charger connects to a device, it performs a “handshake” asking the device how much power it needs. USB PD supports seven voltage levels at 5V, 9V, 15V, 20V, 28V, 36V, and 48V.
