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.

+Nathan K. Digging up an older post here. When you say Apple-esque charging is affected, does that mean that the 5" Pixel won't necessarily "charge rapidly" with this cable and a 5V/2.4A charger? Currently using the OEM A-to-C cable in my car but looking to replace it with something like this.
 
+Neil Konouchi​​​​​​​ I would not recommend this cable. Please consider the Belkin instead. I am referring to a technique called "current ramping". The Pixel determines a current level to draw based on when the voltage drops below a certain level. Because this cable's resistance (therefore voltage drop) is so high, it will pick a charging rate at a far slower value than it otherwise aught to.

Picture example attached of a "3a" charger maxing at 1.2a. Blue line is current. Red line is voltage. It "ramps" current multiple times trying to tests its limits (seeing where red line drops down), then settles on a value.
