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 : [[ASIN:B015X29HLM Plugable USB 3.1 Type-C (USB-C) Power Delivery Sniffer]]
For my first test, I've got the Tronsmart USB 2.0 Type-C to Type-A cable plugged into an Apple proprietary Type-A charger, the stock iPad Air 2 charger.
The Type-C end is plugged into Twinkie, acting as a pass through to Chromebook Pixel 2015. Picture attached!
First let's run the ectool command from Pixel's command line to check what Pixel thinks is happening on its USB-C ports :
localhost / # ectool --name cros_pd usbpdpower
Port 0: SNK Charger Proprietary 4643mV / 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 (the USB PD sniffer) says :
> tw cc
CC1 = 413 mV ; CC2 = 10 mV
The tw cc command reads the instantaneous voltage values from the CC pins. As you can see here, CC1_PD pin has a value of 413mV. 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 USB cable has the correct 56kΩ pullup resistor!
One more command :
> tw vbus
VBUS = 4733 mV ; -2037 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 4.733V from the Apple adapter.
For a USB 2.0 High Speed data test, I’ve hooked my Nexus 5X and my Pixel C to my Chromebook Pixel via the Tronsmart Type-C to Type-A cable to test large file transfer via MTP. It just works, no problem!
Now for more subjective judgments of this cable : The Type-C plug on this cable is a stamped metal part that's been wrapped around to the shape of the plug. It does have a seam on one side. Not my preference, but the
In conclusion : A high quality charging and data sync A-to-C cable from Tronsmart! The cable is a great safe way to charge and sync newer USB Type-C devices such as Nexus 6P/5X or Pixel devices with your old Type-A equipment. It is future proof for fast charging USB Type-C devices to come!
Benson here again, continuing my reviews of USB Type-C legacy cables, adapters, and accessories. I've been getting and reviewing these to try to separate the good from the bad in the emerging Type-C marketplace. Today I am reviewing Tronsmart's USB 2.0 Type C (USB-C) to Type A (USB-A) Cable, 6ft.
