Bests & Worsts Reviews from Amazon

Note : this cable is identical, down to the markings on the cable and the brand on the box as this cable from GT-Coupe : Type C Cable,GTcoupe Gold Plated 3 Feet/1M USB-C to USB2.0 Charge Cable Data Sync for Google Chromebook Pixel,MacBook 12inch,Nexus 5X/6P Huawei P9 LG G5 tablet I had previously reviewed this cable, so the review I am posting here for the OKPOW cable is identical. Benson here again, continuing my reviews of USB Type-C legacy cables, adapters, and accessories. Today I am reviewing GT Coupe's 1M USB Type C (USB-C) to USB 2.0 Type A cable. Let's check spec compliance : I'm using my trusty Chromebook Pixel 2015 with the Chromium Twinkie USB-PD Sniffer, available on Amazon from Plugable : Plugable USB 3.1 Type-C (USB-C) Power Delivery Sniffer For my first test, I've got the GT-COUPE cable plugged into an Apple proprietary Type-A charger, the one that comes with the iPad Air 2. The Type-C end is plugged into Twinkie, acting as a pass through to Chromebook Pixel 2015. localhost / # ectool --name cros_pd usbpdpower Port 0: SNK Charger Proprietary 4744mV / 2000mA, max 5000mV / 2000mA / 10000mW Port 1: Disconnected So far so good. Pixel identifies the charger as a Proprietary type adapter, and has negotiated 2A 10W of charging. Let's see what Twinkie says : > tw cc CC1 = 414 mV ; CC2 = 16 mV The tw cc command reads the current voltage values from the CC pins. As you can see here, CC1_PD pin has a value of 414mV. 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 = 4737 mV ; -2031 mA The tw vbus command uses twinkie's current and voltage meter ability. As you can see, the laptop is pulling just around 2A of current at 4.737V from the Apple adapter. For a data test, I’ve hooked my Nexus 5X to my Chromebook Pixel via the GT-COUPE cable to test large file transfer via MTP. It just works, no problem! For more subjective aspects of this cable, this cable stands out with its distinctive gold plated connectors on both the Type-A and Type-C plugs. Furthermore, the Type-C plug on this cable is also made using the deep-draw extrusion method much like the Apple and Google plugs, meaning the connector is stronger and doesn't have a visible seam on one side of the plug. The tip is also nicely rounded off so the edge of the plug isn't sharp. Overall, a very nice set of aesthetic choices by GT-Coupe. In conclusion : A high quality charging and data sync cable from GT-coupe. 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 also future proof for fast charging USB Type-C devices to come!
