Do I need a special charging cable to charge full rate and USB hub/dock suggestions

[Fraoch]

Confirmation that the Framework-supplied cable has an e-marker chip and is capable of 100W power delivery:

What are the specifications of the USB-C charging cable?

It’s a 5A cable with USB 2.0 support. It does have an e-marker to allow 100W.

and that every cable should be capable of 60W, but that you need an e-marked cable to deliver more than 60W:

What are the specifications of the USB-C charging cable?

100 W USB-C cables are electronically marked using a chip, I believe chargers will not supply more than 60 W (which is the minimum every USB-C cable should be able to provide) unless they detect that the cable is rated for it. So it should be a binary yes or no for that part. Unfortunately this spec is often only listed on the cable packaging and not the cable itself, so there’s no way to know for sure just by looking at the cable as far as I am aware.
