Bests & Worsts Reviews from Amazon

Benson here again, continuing my reviews of USB Type-C legacy cables, adapters, and accessories. Today I am reviewing "Anker USB-C to Micro USB Adapter" by Anker. This comes in a convenient 2-pack. 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 Anker MicroUSB Adapter plugged into a good quality (itself capable of >2.4A) Micro-B cable from Belkin. (this one: Belkin 6-Foot 2.0 USB Type C (USB-C) to Micro USB Charge Cable, USB-C Certified) . That is then plugged Apple proprietary MacBook charger capable of 5.2V at 2.4A. 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 --dev 1 usbpdpower Port 0: SNK Charger Proprietary 4744mV / 2400mA, max 5000mV / 2400mA / 12000mW Port 1: SRC So far so good. Pixel identifies the charger as a Proprietary type adapter, and has negotiated 2.4A. Let's see what Twinkie (the USB PD sniffer) says : > tw cc CC1 = 22 mV ; CC2 = 434 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 434mV. 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 MicroUSB adapter has the correct 56kΩ pullup resistor! One more command : > tw vbus VBUS = 4818 mV ; -2450 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 4.818V from the Apple adapter. For a HighSpeed USB 2.0 data test, I’ve hooked my Nexus 5X to my Chromebook Pixel via the Anker MicroUSB adapter + Belkin MicroUSB cable to test large file transfer via MTP. It just works, no problem! Now for more subjective judgments of this adapter : The Anker adapter has a black glossy overmold with the Anker logo on it. The whole thing is very small, barely larger than the Type-C or Micro-B connectors on both ends. The Type-C plug on this adapter is a very unique for a Micro-B adapter because in typical Anker fashion, it uses a very good quality plug made with a deep-draw extrusion process. The plug is a single continuous piece of metal all the way around, meaning it's stronger than other stamped type plugs. This type of plug is the same kind that is used on all of Google and Apple's Type-C plugs, and the quality shows here. In conclusion : A high quality charging and data sync MicroUSB Adapter from Anker! The adapter is a great safe way to breathe new life into your old A-to-MicroUSB cables for use with newer 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!
