For my first test, I've got the iOrange-E cable plugged into an Apple proprietary Type-A charger, 12W version.
The Type-C end is plugged into Twinkie, acting as a pass through to Chromebook Pixel 2015. Picture attached!
localhost ~ # ectool --dev 1 usbpdpower Port 0: SNK Charger Proprietary 4618mV / 2400mA, max 5000mV / 2400mA / 12000mW Port 1: SRC
So far so good. Pixel identifies the charger as an Apple proprietary type adapter, and has negotiated 2.4A of charging.
Let's see what Twinkie says : > tw cc CC1 = 18 mV ; CC2 = 426 mV
The "tw cc" command reads the current voltage values from the CC pins. As you can see here, CC2 pin has a value of 426mV. Referring to the USB Type-C Specification Table 4-25 Voltage on Sink CC pins, this voltage falls right in the middle of the range allowed for vRd-USB, meaning that yes, this cable has the correct 56kΩ pullup resistor!
One more command : > tw vbus VBUS = 4707 mV ; -2447 mA
The tw vbus command uses twinkie's current and voltage meter ability. As you can see, the laptop is pulling just around 2.4A of current at 4.707V from the Apple adapter.
For a data test, I’ve hooked my Nexus 5X to my Chromebook Pixel via the iOrange-E cable to test large file transfer via MTP. It just works, no problem!
For a USB 3.1 SuperSpeed data test, I've hooked up my Pixel C to a Windows 10 laptop using the iOrange-E cable, and verified that it indeed enumerates at SuperSpeed using the USBView.exe debug app, and that large file transfers are stable. This is a great cable to have for MacBook users especially who want to use Target Disk Mode, which requires a SuperSpeed capable USB cable.
For more subjective evaluation of the cable : iOrange-E’s cable has aluminum shells on both ends, which meshes well with the all aluminum new MacBook, Chromebook Pixel 2015 and Nexus 6P. The braided cable is very nice, although since this is a SuperSpeed cable, it has 4 additional wires inside, meaning that this cable is noticeably thicker and stiffer than iOrange-E's 6ft USB 2.0 cable. iOrange-E also ships a handy velcro cable tie with this cable as well. Much appreciated. The C plug is a stamped variety, meaning it has a seam on one side of it, unlike other cables from Apple or Google which have deep-draw extruded plugs which is stronger.
Finally, I just want to mention that iOrange-E's cable is amongst the longest USB 3.1 A-to-C cables available on the market today at 6.6ft long. Most other A-to-C cables max out at about 1M or 3ft. When making cables longer, issues of signal integrity and power capability (longer cables may cause more IR drop and may result in much slower charging) will come up if the manufacturer is not careful, but iOrange-E's cable performs well in my charging and data transfer tests. Also, even compared to other USB 3.1 cables that are shorter, the iOrange-E cable's nylon braid makes the cable feel thinner. Really quality fit and finish for the actual length of the cable!
In conclusion : This is a fine USB Type-C cable from iOrange-E. The cable is a great safe way to charge and data sync your new USB Type-C devices such as Nexus 6P/5X or Pixel devices. It is future proof for fast charging USB Type-C devices to come, as well as future proof for USB 3.1 SuperSpeed devices!
