USB-C Power Delivery (PD)

[B1ng]

Hello Fine Forum Folks.

I am looking for some information and experiences on using USB-C Power Delivery, or PD, in conjunction with newer mobile device and Laptops.

The standards and Internet Searches only bring more confusion.

The reason to ask is this; I have, as I suspect others do, a multitude of Laptops, Phones and Tablets with a variety of USB-C chargers and cables. I am finding that only certain combinations of cables and chargers will work between devices. This is especially true when a device requires more power, such as a Laptop. All pieces in the chain (Charger, Cable, Laptop) support the same 'standard' of power.

Is there somewhere that makes sense of all this, or is the multiple variants of PD standards really such a mess?

Thanks for the responses folks!

After a little more digging (and picking up a cheap 45w PD unit), things are still no clearer.

I'm not sure at this point if my current daily laptop is just picky, or if some of the newer chargers I have (65w and 100w PD) can't negotiate down for some reason. Different cables, all 'rated' up to 100w, behave subtly differently. Some refuse outright to charge, some will charge slowly, some only charge when the Laptop is in standby. The bargain bin 45w charger just works, with all cables I have.

Steam deck, PD in portable battery pack work fine in all cases. Going to write it off as another of the universe's great mysteries.
