I haven’t yet worked out why cheap 100W PD cables partially fail after about 6 months.

They can still provide some power, but between a MacBook and official Apple power supply, they’ll keep flicking between charging and not charging.

Likely the emarker chip in the cable is reporting higher power capabilities than the cable can support long term. It'll work initially but then can't maintain that after resistance in the wires increase with wear.

My personal favorite is the usb-c cable that works when you rotate the connector upside-down.
