[Attack of the Cables!] 18th #USB #TypeC analysis: Plugable USB3.1Gen2 USB-IF Certified eMarked C-C cable. [Model USBC-C100]
tl;dr: GOOD. Properly eMarked 3A, USB-IF certified, economical, good support. High IR drop could be improved.

(These analyses will be a lot shorter, and rapid-fire. READ THE PDF.)

Here's a question: if manufacturers everywhere are breaking the rules, and you find a name-brand cable that is decent, cheap, reliable, and has good support -- do you go for it? Or push your luck? (Shopping mall parking hypothesis.)

This cable lies perfectly within USB-IF Specifications. It is properly USB-IF certified and eMarked, and the company itself is "honorable", for lack of a better word. But I will point out two hiccups in the design:

https://en.wikipedia.org/wiki/Zero-based_numbering

First, the "Product ID" field in the eMarker on some cables appears to be "Zero". If you are a computer guy/gal you know what "zero indexing" is. But do product numbers allow the same rules? To my eyes, "zero is a number" so it's OK, as long as it's unique and never re-used for another product. However, poorly-coded USB-C devices might scan the eMarker, see a zeroed out "Product number" field, and naively assume it's not there. So it's something to be aware of.

Second, the IR drop causes some charging issues on the Google Nexus 6P. (More on this in another post, later.) This is allowed for in the USB-C spec, and Plugable is doing everything by the rules. But again, a "problem device" that isn't following the rules is having trouble.

So if you want an USB3.1Gen2 cord "just to have", or for general use -- I recommend grabbing this since it is reliable and *literally* half the cost of the Belkin.

Hey I've got a question about the 15W charger that comes with the Pixel C, is it safe like the 22W charger?
 
+Zachary Batten​ I have mixed thoughts about that one. I haven't analyzed it fully. However, it is captive cable (looses the benefit of USB-C one-cord-for-everything), Vbus HOT (permissible on captive cord but inelegant/crude), and made by the same manufacturer who botched the 6P charger (Salcomp). So I'd say you are fine, but I wouldn't buy another one for money.
 
+Nathan K. Thanks for replying, I'm using it as my main charger for both the 6P and Pixel C. I'm happy to know that the 22W one is the safest 
 
Do you still recommend this (November 2016)? Or are there any other C to C 3.1 gen 2 cables that can be found on Amazon AND you recommend? Thanks and greetings to you from Colombia 🇨🇴
 
+Harold Juan Pablo Castro​ If it is USB-IF Certified (blue and white logo), it is safe. In theory. No need for me to check.

It may not be a good VALUE, or function WELL for certain needs, but is safe.
 
Understood. Turns out the Belkin cable I asked about was already on a recommended list that Benson has on his Amazon profile. Thanks for your prompt responses and for helping making the transition to a USB C connected world a little easier!
