is there a kernel or ROM that allows the nexus 7 (WiFi) to be charged wireless while OTG is in use? I'm trying to install it in my car and need my phone plugged into it via OTG. but I would like to charge wirelessly. I think I can get OTGy cable to work if it comes down to it.
Thats not possible

Why no use one of these? Elemental x kernel supports usb org + charging.

So i ordered USB HUB and OTG cable and made this: http://shrani.si/f/3m/Qg/JfkMcsx/20130808144649.jpg
Everything is working fine, just the battery life is short.
So i was wondering if I can connect USB HUB with A-A USB to USB Power Adapter (http://image.made-in-china.com/2f0j00CefTLRdzJBgP/5W-USB-Power-Adapter-MEU-.jpg) and charge my Nexus 7.
Greetings.

You won't be able to charge the nexus that way - you'd need a custom kernel for that (there's one for original nexus 7).
I'm planning on doing something similar, I'm wonder if a powered USB hub would at least power your USB accessories (I'm going to plug in a DAC and Hard drive).

Not for a few months at the very earliest would be my guess.
They make a otg cable that has a power port on it to power the flash drive so it don't drain your battery. I know amazon has them.

Would someone with a TabPro 10.1 please answer the following charging questions?
How long does this tablet take to fully charge from 25% or less charge?
If you attach a micoUSB OTG cable to a powered USB hub will the tablet still charge while using a device (USB harddrive, SDCard reader ... etc) that is also attached to the powered USB hub?
Can a microUSB OTG Y Cable concurrently charge from the standard USB charger and run an OTG USB device (e.g. SD card reader)?
I'm asking as I currently use a Nexus 10 attached to a powered hub with a USB ethernet adapter attached. Unfortunitely the Nexus 10 does not utilize the charge provided by the powered USB hub and looses charge. In this set up the powered hub only helps to power the Ethernet adapter so overall the Nexus 10 does not discharge due to the Ethernet adapter. I am hoping the TabPro 10.1 has a better charging implementation than the Nexus 10.
FYI: The Nexus 10 will not charge from its pogo connector when the micoUSB port is being used for charging or with an OTG device. The charging notification falsely indicates the device is charging.
Thanks for anyones insights.
I would like to know this too. I've purchased and the Note 10.1 2014 and this is the only issue I have with it is the lack of support for charging and USB OTG use. If the Tab Pro 10.1 or even 8.4 can charge with OTG I may exchange the Note. Thanks!
I just tried an OTG Y cable, it wont charge. I also tried a trick that worked on my lenovo windows 8 tablet where you turn the tablet off, turn it on with charger in, rip out the charger and plug in the OTG cable before it fully boots and then connect the charger to the OTG cable which allowed OTG+Power, didn't work on the tab.
IIRC this is something that can only be changed by a kernel modification as I think the old 2012 Nexus 7 could do this with a custom kernel, but I could never find a working download.
EDIT: Tried on my Tab Pro 8.4 running latest CM nightly
Hi all, I have the Nexus 5 and wish to connect the TP-LINK TL-WN722N USB Wifi Adaptor but I am having no success, I purchased a Y Cable to connect it to my phone but when i plug it in nothing happens on screen or no light comes on the Wifi Adaptor, I plugged my charging cable into the other end of the Y Cable but it doesn't charge the phone, I thought my cable must be faulty but i've now used 3 more and all with the same outcome. Is there something i need to do to my phone to get this to work? The port on the phone works fine as it connects to my computer and charges perfectly when i just use a normal cable. If you can help me it would be greatly appreciated.

from doin this on my nexus 7 to use nethunter kali with the wifi adaptor i would say you need a rom and kernel that support usb-charge and host. stock android doesnt support wifi adaptors . u can access and use the adaptor in a linux kali but you cant use it in stock android to say browse the web instead of using on-board wifi chip/card.
edit : Also most of the y-cables you can buy from e-bay dont actually route power to the phone/tablet and to the attached device, the power only goes to phone, i had to make my own charge/host usb cable with a soldering iron and heatshrink tubing. this cable charges the phone/tablet and provides steady power to the attached devices (wifi adaptor, mouse,keyboard,hard-drive) the ones i mention previously from e-bay dont provide enough juice to power the adaptor.
You need a custom kernel with module loading, root and your wifi adaptor´s module, altough my WN723N and a cheap old ethernet adaptor worked out of the box(chroma rom with elementalx kernel)

Many thanks for your reply, I will try these now and see how i get on
Hello,
As explained in title, I am looking for a 3-4 usb hub that supports otg and can charge the Nexus 7 at the same time at full voltage, without drain.
Any ideas? thanks

Yes http://www.ebay.com/itm/201372917160
but I'd prefer http://www.ebay.com/itm/191859127277
You will also need a kernel
What are you trying to accomplish

Forgot to mention, I'm doing a car install. I'm currently using Elementalx Kernel with Otg charge enabled.
hi there, im crazy with this
i got a nexu 7 2013 wifi, as like you I use CM 13 with elementalx installed and otg and charge enable.
i use a Y cable, a hub cable too and any works.
if someone can explain or tell me why.....i need it for my car

Otg splitter and hub is so you can power your tablet and any devices that are connected to the hub .. Ex. Joycon , video grabber , dac ...ect
Timurs kernel is the most reliable but you have to donate to get it ... Elemental is free but sometimes has issues with otg/charge bugs upon wake
You need the ability to enable Fast Charging for the kernel.
Simple USB-OTG won't get you full charge speed.
I know Timur's kernel for 2012 model has a Fast Charge option that is probably also available on the 2013.
And ElementalX kernel *might* be getting that option soon too, if not already.

You need to install a kernel for otg and charging ....
Two options
Elemental kernel ....slightly buggy loses charge on boot
Timurs kernel ...works flawless ... But you have to donate ...

Hi,
I've been doing some research on using an OTG USB-c cable/hub/y-splitter for data and simultaneous charging capabilities for the 5t. After sifting through forums and Google, the issue is the 5t can't use OTG data transfer and charge itself at the same time; it can only do one or the other (confirmed with my own experiences). I read that the cause might be because of the stock kernel not allowing for this. Would anyone know of a custom kernel for the 5t that allows OTG Host mode and charging simultaneously?
My use case would be to use my 5t to hook up a USB DAC over OTG cable/hub/y-splitter and then use the other USB port to connect to a wall charger to keep my phone charged while using the DAC. It could also be used for other devices that connect over OTG without draining your phone battery for extended use.
- Thanks
