Take a look at there. Personally I wrote many times "kidigi". :D

Here's the converrsation:

I get a review from Kidigi about the first USB type c dock ever. here's their results:

"Dear Kamaji,

I had a quick test on my newly purchased Nexus X5 with the following setting:

- Nexus X5 (32G), Hong Kong version

- KiDiGi LC-UTC

- Apple Macbook Pro

It was working normal at 4.8-4.9V / 0.89A – 0.98A, the screen of X5 showed ‘Charging’

After 20 minutes, the Macbook Pro was working normal and all the connectors (Type-C to Nexus 5 & USB 2.0 to Macbook Pro) were in normal room temperature.

- Nexus X5 (32G), Hong Kong version

- KiDiGi LC-UTC

- KiDiGi 5V/2.1A Adaptor

It was charging normal at 4.9V – 5.12V / 0.95A – 1.05A, the screen of X5 showed ‘Charging’ and sometime jumped to ‘Rapid Charging’.

After 20 minutes, the Nexus 5 was getting a bit warm and the Adaptor was at normal room temperature.

To my understanding, the 56 kΩ Pull up Resistor is used to identify (the cable or the dock) itself as a “Default USB 2.0 Power”, then the 5X will only ask for a default current (i.e. 1.0 – 2.4A).

When the cable / the dock uses a 10kΩ Pull up Resister, the 5X will ask the source of power (AC Adaptor / Notebook Computer / USB Hub) for 3A current. Surely if the source of power (AC Adaptor / Notebook Computer / USB Hub) is able to provide 3A current, then that will damage the Type A connector (as USB 2.0’s default current is only 2.4A. But if the source of power could only provide 2.4A or below, then the dock should be fine……

My engineer will perform testing overnight tonight and I will let you know more.

Thanks

May you take a look at this? What's the meaning? Yay or nay? :D﻿

+Onur Kazancı That is actually quite encouraging. It sounds like you pointed out that there may have been an issue with their product, and they actually consulted their engineers, reread the specification, and decided that they made a mistake and are working on fixing it.

They are doing the right thing here. We should support them! I will definitely buy one of their docks for review.

+Onur Kazancı I'm not on the Nexus team, actually, so I can't talk about product decisions about the phones.

If you get the dock in the mail, I recommend returning it to them and waiting until they fix the identifier resistor first.﻿
