Basically I'm trying to figure out if I should just throw these out of my cable bin, or if they're actually decent enough to use.

Okay, so, reading Wikipedia and the PD spec and continued testing has convinced me that these cables won't go >60W because that requires actual chipping so the adapter/computer know its capabilities. But they shouldn't be restricted below that unless they have actual pins missing (and I'm not […]

Now I'm wondering if my meter supports > 100W though, so I can't even test 140W support.

Hmm, specs page claims it does, I really thought it was older than the 240W spec... don't necessarily trust them to have not reused the model number, but oh well.

tim.union.place.ap.brid.gy•46 days ago

Not 100% sure what device-side stuff I have that I'm sure does 140W...

tim.union.place.ap.brid.gy•46 days ago

Come to think of it I also don't know if I have any 140W cables

I sure wish there was some consistent external marking to go with the chipping. 😑
