I have everything planed out for my tab install for my Dodge Magnum. But since the Nexus 7 doesnt have a sd slot I need to find a cable that can charge the tablet and use my flash drive at same time.
My flash drive(Usb on dash, so its easily removable)
http://www.amazon.com/gp/product/B00812F7O8/ref=ox_sc_act_title_4?ie=UTF8&smid=ATVPDKIKX0DER
Plugging this into the usb otg cable
http://www.amazon.com/Black-4-Port-...qid=1348442221&sr=8-3&keywords=4+port+usb+hub
I would love host cable with 2 usb inputs but cant seem to find it and dont know if its even possible.
Any help would be appreciated.
I found this on the bay : item # 140839631580 (Can't post link I'm too new... I was a lurker for a while -_-)
i didn't think the N7 could support power and OTG
You want it for video or audio? You could try a wifi solution for audio. Or be the guy that gets the pins to work.
there is NO data and charge at the same time. This is due to how the device switches from charge to usb mode thru the pin 4 . it senses rather a data cable or charge cable is being used . will not charge via otg..
there are several threads with experiments trying to get this work .You could use a wifi or bluethooth drive for data...
I have no clue what im doing but this is what im playing with at the moment. Its a old dock for sgs2 i believe but it has a dc and usb input on the back of it.
Im about to this because i have very little patience for china.

Would get the cheaper one but the juiced one has a flexible cable vs the fixed usb on the other one. Would this be pointless though?
Unfortunately OTG sends ground up the sense pin to trigger host mode. Once activated it sends 5V DOWN the USB cable to power your USB devices. Trying to send voltage up the cable at the same time to the Nexus would not be a good idea. The only way around it I can think of would be to hack the firmware to only activate the data pins in host mode and keep the power circuit seperate, then you could power the USB device from a modified dock/hub which sends power up the USB cable to the device.
A lot of work, and without the powered hub, OTG would be useless!
In the long run wouldn't it be easier to just plug in the power lead when needed and have the otg in the rest of the time? (or vice versa). It would mean you having to have easy access to the usb port but I can't see an easy non technical solution to connecting both at once.
Don't use the Nexus 7 for a car install. You can get an Acer Iconia A100 with a full-size USB port to connect to whatever external storage solution you want, and it's usually about the same price or cheaper than the Nexus 7.

Would it be possible to charge while using an OTG Cable for Keyboard/Mouse or does the same principle apply as inn data via OTG & charge?

Same principle. In normal OTG host mode the tablet powers the peripherals. A USB keyboard/mouse will be no exception to that.

Sorry to resurrect an old thread but was wondering if you ever ended up getting that Juiced systems adapter and if it worked well with the N7. Been looking at it but haven't found any success stories on XDA with the N7, just the few Amazon reviews...
That cable would work but u need specific kernel tweaks for otg + charge to work. Pm me if anyone needs it.

Ofcourse there is charge and otg at the same time by just simply shorting pins 4 and 5 with a resistor,in my case for xperia p , a 100k resistor does it.
Timurs USB ROM from another site is what you want. Has links and everything you need.
I was going to do a car install as well but after sourceing parts and work estimates ( I want clean install, like stock) just more hassle than its worth for me. Please post pics if you get an install going.

That's because the iPad charger doesn't have the data pins shorted out to enable fastcharge . Easiest way to accomplish fastcharge with your charger, is to buy a charging cable (data pins shorted out, so it is not a data cable:
http://dx.com/p/usb-male-to-lengthe...for-samsung-i9500-9300-htc-white-100cm-207353
It even has the lengthened micro usb connector the Nexus 7 needs.
Or maybe better, buy this one, found in another thread here on XDA, this one is confirmed to work in fastcharge mode with any usb charger:

Yes I know, and that's the reason the iPad charger won't work on fastcharge.
You need to either shortout the data pins of the iPad charger, or use a charger cable with shorted data pins ( a so called charge-only micro usb cable) to make the iPad charger use full capacity (fastcharge mode). There are also cable adaptors for sale that will shortout the data pins for you.

Yep, that one works because it follows the USB standard rules, and not the Apple USB standard.
No iDevice (iPhone/iPad) charger will fastcharge an android phone or tablet without modifying the datapins or use a charge-only cable / adaptor.
The Blackberry Playbook charger is known to work
Get an HP touchpad charger if you can. I can provide empirical evidence that it will actually charge your n7 20 minutes faster than the stock charger. I posted a thread about it here some time ago. "Best aftermarket charger ..." Or something like that.

I will suggest the HP touchpad charger for use with the N7... they work great and produce no noticeable heat when not connected... shows good efficiency.:good:
Check Ebay -= just did a quick search and got 131 hits anywhere from 8-20 USD. I"ve bought 2... one is firmly set to be my preferred travel charger for any USB device.

Someone did a in depth look at factory and aftermarket chargers and it came out way better in terms of current provided and cleanliness of power without spikes or dropouts.

That will do the trick - but you don't need another cable if you already have one.
I went with the charger without cable option and got 2 chargers for less than that price. Just have eBay sort the search results by price+shipping and optionally USA sellers only to find a better price without waiting for a slow boat from China.

If the charger puts out less than the tablet needs then it will just charge slower (or not at all if it's really low) and if it puts out more than the maximum the tablet uses the extra will just go unused. Voltage is a different issue.

Having your device plugged into a USB 2 500mA computer port obviously charges slower then a 2000mA wall charger. It would be pretty faulty design if plugging your device into your computer would cause hardware damage.
Man, this really sucks, the Monoprice cable mentioned earlier in this thread is having the same issue I had with another micro USB cable, it doesn't seem to fit into the Nexus 7 snugly, it doesn't seem to go in all the way. (I hope I don't have a busted charging port), It doesn't seem to charge it at all, even with the stock Nexus AC adapter. I'm about to break down and buy the official Google charger again, even if all I need is a new micro USB cable.
I'm using 2 different monoprice cables, one in my car and one at home, and both fit well. Sounds like the port has gotten damaged.

So, I just decided to buy a whole new charger off Amazon. If that won't work and I determine that the micro USB port is busted, I'm not going to be very happy, haha. does anyone know if Google repairs them for a fee?
I use a Playstation Vita charger which seems to charge my N7 very fast. On the other hand, I've tried an old mobile charger also and the battery level goes down whilst plugged into it.
If under warranty and purchased from the PlayStore, yes, otherwise, if under warranty, ASUS.
Hi everyone @xda,
Here's a new thread I wanted to open to share a recent experience.
I currently have a Nexus 4 and a Nexus 7. Both are recent ones and I have myself newly fallen into Android and tablets.
So far, I only had small cell phones and I could charge them with almost every charger and USB cable in the world.
No so easy with the Nexus 7.
First, it seems it's charger delivers a thick 2.6A so any charger weaker than that, and the full charge would last for ever...
But another weird thing is that I noticed that, if I use the stock charger with another USB cable, the charge is SSSLLLLOOOOWWWW....
Even better. I have the dedicated Nexus 7 dock.
If I use the USB cable that came with my previous Sony Ericsson mobile, the Nexus 7 won't even consider it is charging.
Same USB port, same dock, but different cable (from Belkin or the stock cable) : no problem, it charges !
So, I have come to the conclusion that the USB cable can make a big difference.
Can I be wrong ?
Regards.
NexusPenguin
Yes.. I broke the USB cable of my Nexus 7 after 2 weeks... The only one who charges the Nexus as fast as the stock is the samsung cable of my SGS2. With another cable (lower than 2A), it takes more than a night to charge my nexus...
Hi Albadros,
Thanks to confirm that...
For a moment I thought I was a little stupid thinking the USB cable could be at fault !
So the cable DOES make a difference... I'll take care of the cable I'll buy from now on
Regards.

It's hard to find an USB cable where the informations are written but you can buy a charger micro-USB and it's written on it. You must have the same as the Nexus charger (2,0 A). (I think a charger for BB Playbook has the good characteristics)
In my experience it has something to do with the cable length and how the charger is constructed...
but there is already a thread about this topic:

In disagreement here. Got my Nexus 7 about a week ago, and right off the bat the USB cable that came with it (asus) was awful. Just like the crap that came with my S3. Not sure how or why, but the USB cable that came with my Pantech Crossover a few years ago is still the best for me. It charges my N7 fast as hell, and it's pretty durable too! Only cable I have that doesn't seem cheaply made, again as confused as everyone, I repeat a PANTECH cable..
Is anybody aware of a wall charger that has both ports for USB A and USB C? I want to be able to charge my 5x along with my girlfriend's s6 at the same time, along with some other microUSB devices. It would be ideal for the USB C port to output 3A and the USB A port to output 2.4A. I've had no luck searching for anything like this.

I'm guessing this is maybe what you're looking for. Not sure if it can charge one at 3.0 and one at 2.4 but it does have both ports. Unfortunately since I am a new member I can't post a link but it's called the "Tronsmart 33W Dual USB Turbo Wall Charger". You should be able to find it if you search on google.

Anker offer a desktop charger with one USB C 3A and 4 standard 2.4 A USB ports, total output 40W. Likely to be over budget though...o
There is the Choetech wall charger with 1 x USB C and 2 x USB A ports. It can do 1 x 3 amp and 2 x 2.4 A simultaneously.
It's reviewed here:
http://forum.xda-developers.com/nex...iew-choetech-39w-3-port-wall-charger-t3315872
I have the UK version and it works great with the 5x. Choetech cables (I have a C to C and A to C) are great quality. I think they make the oem cables for Google (I'm sure someone will correct me if this isn't right)
this one is also pretty good, just don't expect to be able to use all 3 ports at max output:
http://www.amazon.com/gp/product/B01A8V6RI4?ref_=cm_rdp_product
perfect for a phone, a smartwatch, and an accessory though
Anyone got a charging dock? or recommend one please OP3 on its way and like to have it stood up next to the bed like!
I would also like any suggestions for a cradle/dock. There are plenty of USB C cradles listed on Amazon and other sites, but they don't seem to support the Oneplus charging system.
Anyone know of a cradle/dock that would allow me to use the USB C cable that came with the OnePlus 3?
well if it's a usb dock overnight charging should be ok regardless of dash or not? I'm thinking if there isn't one soon I'll make one or something using a dash cable.
This one I am looking:

It is Benson-tested (Benson is the Google Engineer that started all the thread about USB Type-C compliancy). It will NOT fast-charge or Dash-Charge your phone, but it will also not make a fire out of your phone. worth a try, I think I will order it soon.
