USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray! (hackaday.com)

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?

I'm in my 40s and therefore generally in the "get off my lawn, kids" age.

But I totally agree with that article. I've converted quite a few legacy devices with barrel jack to USB-C - and got rid of a huge box of junky old power bricks. Especially for devices I only use occasionally I don't want to search for the matching power bricks - I just want to plug it into one of the 4 USB-C PD sockets I have installed into my desk.

How difficult is it to retrofit that into older devices? Because I'd love to get rid of my."Miscellaneous Power Cords/Adapters" box on my storage shelf.

If you can solder and heat shrink then search for "usb c trigger board" on ebay and get some for like $5. They will request either 5v, 9v, 12v, 15v or 20v. I've found for most older battery powered barrel jack devices a voltage that is an little under spec works just fine. Ive convertered everything in my house and now own a nice USB PD battery bank, life is good.

pretty easy, if soldering is easy:
