25th #USB #TypeC analysis is the Anker PowerLine+ USB 3.0 A-to-C cord. [Model A8168091]
tl;dr: SAFE. Very nice fit and finish. But IR drop (.50v) is high, double the resistance of some A-to-C peers. Also not eMarked, only 5gbps.

This was pseudoanonymously donated from my Amazon Wishlist courtesy of "PK",  so I'm evaluating it. This is an incredibly fancy cable. Braided cloth construction, leatherette pouch. Cables are individually serialized. Major kudos to +Anker on all that!

Cable is SAFE. 56kR resistor, and wired correctly. Downsides are no eMarker and it only claims 5gbps support. (USB SuperSpeed = 5gbps, not USB SuperSpeed-Plus = 10gbps)

I am very concerned about the high IR drop/resistance. With 3A passing over it there is a drop of .50v. In comparison, the Belkin "Apple Store" A-to-C 3.1 10gbps cable drops .28v. This means the cable resistance is near double, and about 1.5W of heat is being dissipated... somewhere. This is likely due to Type-A contacts being a poor conductor compared to Type-C, or Anker using a cable with uniform data/power wire size, instead of larger Vbus/GND wires.

Belkin "Apple Store" A-to-C 3.1 10gbps for reference (.28v):

This is a concern since some recent phones (Note 7) are USB-C noncompliant, and use proprietary Samsung Adaptive Fast Charging or Qualcomm QC3.0 over Type-C. By default, compliant USB-C only permits 500/900mA over A-to-C --  with more if special signaling is used. However QC3.0/SAFC put up to 3A through without question.

Were you to use this cable with a noncompliant charger, you may notice some odd charging behavior due to the high cable resistance and high currents involved. (Apple-esque 2.4A D+/D- charging would be affected as well.)

All in all this cable is safe to use and very nice looking. But electrically and speed-wise, it performs moderately.
