Power Bank & Type C wires
https://www.youtube.com/watch?v=gEG9er0kLqA
I feel a QC 3.0 Power Bank with built-in Type C wire, which can be charged with a Type C wire is Best :good:
If you have any suggestion please share

Hello guys, I'm trying to interface android tab with peripherals. Problem is, it is having only one micro USB port which is used for charging and otg/host, only one function is possible at a time .But I need to charge the tab and simultaneously transfer data to peripherals, say for example I need to use external mouse and charge the tab at same time.
So, is there any way to do it?
I know usb has 4 pins 5v,d+,d-,gnd. I thought to wire charging input power to tab pin 5v and gnd and pin D+,D-of tab to mouse D+, D- and giving external power supply to 5v and gnd pin of mouse.
Is this a right method? To charge and transfer the data at the same time?
Kindly help me. Suggest a better way to do it.
(mini & micro) USB connectors have 5 pins: Vbus, D-, D+, Id, Gnd.
For OTG, the Id pin is connected to Gnd.
It's like the old adage, "You can lead a horse to water, but you can't make him drink."
You can connect a peripheral to an OTG host and have it work fine.
You can then connect an external power supply across the Vbus and Gnd.
The problem is, how does your host device know that it can "drink"?
There are basically two ways.
If the host detects power on its input before it switches into OTG host mode it may continue to charge.
If the host is in OTG host mode, device-specific commands to the charging circuits may convince it to charge.
There may also be non-standard Id resistor values for signalling host & charge for some devices.
I think your mileage would vary very much depending on what devices your using. AOS was not meant to deal with people hacking on the USB port, and probably the code to implement those features depend on your HW/FW.
If its a Samsung, you can play with some resistor values like these:

I think the USB "CarKit" specifications should allow you both to charge and "connect" in some way.
A more easy solution would be to use a BlueTooth mouse and keep charging as usual.
I'm installing a 2013 Nexus 7 into my car. I plan to load Timur's ROM on it. I have an OTG cable. I've also purchase a USB Y cable and a USB hub which i'm waiting to be delivered. Will a USB Y cable separate power and data? meaning will one USB port have power and the other data? seeing as I want to connect the data to a USB hub, the hub itself will need 5V power too.
I've sketched up a little idea which is attached below. Can anyone tell me if such a thing will work?
The idea is to have +12v ignition wire and ground from the car going to a 12v > 5v converter. The output of that converter will then provide charging power to the Nexus via the + and ground wires on the OTG cable. This leaves the + and - data cables untouched. Then the idea is to take the + and - data cables directly to the USB hub. And seeing as the USB hub also requires 5V power through its main feed USB, i can provide the same 5V power thats coming from the 12v > 5v converter.
This is just an idea, not sure if it will actually work. Other thing I can do i just stick with the Y usb cable.
Any suggestions and comments would be greatly appreciated.
Thanks
Using active USB hub with +5V You do not need Y-cable, just standard OTG cable.
I'm using this config with ElementalX kernel with N7 as external navigator/videoreg.
I'd suggest to browse through "InDashboard install" threads in "N7 2013 -> General" board for other tips and tricks.
Quick question for you.
I've just ordered a Nexus 6P and will have to change all my chargers at home and at the office.
Of course I'll only use cables purchased at the Google Store or cabler reviewed by Benson Leung.
What about wall chargers? Can I use 3A USB Type A chargers or should I upgrade those as well?
Thanks and sorry for re-posting. I just haven't found antyhing about the bricks. Only the cables.

A charger with a Type-A socket paired with a spec-compliant Type-A to Type-C cable will be able to provide a max of 2.4A of power. The only way to get more than 2.4A out of a Type-A charger will be to use a non-compliant Type-A to Type-C cable. In reality though, few chargers out there will actually give you 2.4A.
A charger with a Type-C socket and a Type-C to Type-C cable can do the full 3A while following specs.
Ok, but will the use of a compliant (Google) A to C cable and an old 1A-2.4A charger damage either my phone, the carger or the cable?

No, it won't. Googles cable is safe to use.
Googles A to C cable is properly designed. If you use a complaint cable (correct 56k ohm resistor) your phone will see it as a legacy charger and pull what the power brick allows it to pull.
Whereas, a non compliant cable (non 56k ohm resistor) will read as a USB 3.1 type C to type C cable to the phone; so it may (will if it's low on power) try and pull 3A out of a cable and power brick that don't support 3 amps.

Thanks. That answers my questions.
Hey folks, so I've done the hard wiring of older phones with MicroUSB and <2000mAh charging before. It was pretty easy by just using a 12V to 5V 3A converter similar to what you see in the attached pic.
Now I want to do something similar for my Google Pixel XL which has a USB-C interface and does smart/fast charging.
Problem is, I'm unfamiliar with this tech and don't want to just wire it up without asking for advice first.
I'm thinking I'll be just fine using the same adapter you see in the pic below.
And I'm thinking I'll be just fine by using the two power wires and two ground wires from the USB-C spliced onto the 12v-to-5v converter.
I do not believe I need to worry about the fifth cable used for signaling between two devices.
So, from the USB-C connector, I would splice its two power wires to the single [out] power wire on the converter. And the two ground wires to the single [out] power wire on the converter.
Then the [in] power and ground on the converter would be spliced into my 12v harness of my car (or Motorcycle).
This should get me full speed charging just like my stock USB-C charger from Google.
Do ya'll agree or am I missing something that may screw things up?

Four of these connections are designated as VBUS connections, carrying the power for charging and operating connected devices. In addition, two pins are used for grounding, and one pin is used for signalling between the two devices to determine how much power should be sent. Running at the USB standard 5 V, the VBUS cables can supply up to 3 amps, a big increase on the 2 amps available in USB 3 cables, and much more than USB 2.

The 12V to 5V 3A converter I use:
post a picture
I've finally ordered my 6P but it does not come with a charger or usb cable.
1: Do I need a power supply that states 5v 3A or are the ones that states 2.4amp enough for full speed charging?
2: does the charger have to be a USB C socket? Or is it ok if it a standard size USB socket and I use a USB standard to USB C cable?
Thank you for your help
you need a 3A with a compatible cable for that amount of current
