From what what i gather the cable must meet the following:

1. Must support USB PD.
2. Must support 5A current.
3. Must be at least USB 3.1.
4. Must have E mark chip.

I just ordered this, but it's only 6ft. I'll let you know how it turns out. The thing that is most upseting is you cant even by 1st party cables from Samsung. I would just buy those.
