brand new nexus 7 16gb, i rooted and the plugged it in to an external battery and it refuses to charge. I've used 3 different cables, 2 different external batteries and it wont charge but my nook and galaxy nexus charge just fine. I plugged it in using hte same cable to the wall or a pc and it charges, anyone know whats going on?
What's the amperage output on it? Honestly 2 is just barely enough, 1 amp out is REALLY slow and any less just won't work.

5v 2amp on the external the battery was the designed to charge tablets
Same issue here, whether I'm using the New Trent 9900 or XPAL 8000. These packs work with other ones and tablets just fine though.
I have 3 USB external batteries with 2A 5V output
that work perfectly for my iPad 2, Galaxy Tab 2 7.0,
as well as my HP Touchpad.
For some strange reason, my Nexus 7 will not allow
it to be charged from any of them.... probably just
how Google designed it?
I think it is an ASUS thing... My transformer has the same issue.. by the way , not all 2A chargers
Work...

I have a New Trent IMP1000, 1A output and it won't charge either. Goes from "Discharging" to "Not Charging" on the battery screen.
Has anyone found a dual car charger for two Nexus 4's or a Nexus 4 and a Nexus 10 whilst in use?
Most dual car chargers seem to have one output to charge Apple devices at 2A plus another output to charge non-apple devices at 1A which is not what I need.
Thanks
I've managed to find something but it seems to be unavailable in the UK

Monoprice has plenty of these. I love their products and pricing.
It might be possible to charge two Nexus 10 tablets or two Nexus 4 phones using a dual iPad charger and power USB cables as described in the first link below.
The second and third links are items from Amazon which might work.

Have you tried to charge your nexus 4/10 with a 2.1a apple USB port? I tried it with both my nexus 4 and 7 and they do not deliver more than 1a. I just ordered the powergen dual USB. It will only give 1a to android devices according to the guys at the nexus 7 forums. 1a is enough to slowly charge my nexus 7 in the car with maps running but im not sure about the nexus 10. We need a car charger specifically made for android tablets that can output more than one amp but I don't know if there are any on the market yet.

If you read the article in my first link above then that says that a dual iPad charger with the correct cable should deliver 2.1A.
Here are some Amazon customer reviews showing that a dual iPad charger can charge a Nexus device at 2.1A when using the correct USB charger cable.

Unless someone tested it with the nexus 7 or 10 im still skeptical. Anytime you see the 2.1a it's designed for the Ipad. Just read that article and it doesn't say anything about android tablets just ipads. Im sure they do output 2.1a but just to ipads, android devices will only get 1a.
Sorry for offtopic a bit but is it okay to use 2A to charge the N4?
I mean does it kill the battery faster or it is totally fine?
THanks

i just read the reviews, just because it shows AC charging it does not mean its output is 2.1a. AC charging just means that its using a charger or cable that has the D+/- pins shorted. I have a moto 700mah car charger that shows AC to both my nexus 4/7 but only delivers around 6-700 mah. What im saying is that it probably wont output more than 1a to an android device. 1a is more than enough to charge a nexus 4(or any other android phone) with nav on but is a bit too slow for tablets. If you do get this car charger let us know if it does output more than 1a. you can use current widget app to find out how much current the phone is receiving from the charger. Im still looking for a car charger that can deliver more than 1a to an android device.

yes it's fine. The nexus 4 will not draw more current than is safe for the battery.

Thanks for your reply. I've ordered the charger and the USB power cable and I'll report back.
I use this
http://www.myinnergie.com/mCubeDC10/Default.aspx
Bought it when I had an iPhone and it could charge it and an iPad at the same time.
Now I use it with the SGS3 and the Nexus 7, works fine for both and they pick it up as AC.

I bought a nexus online and it charged with factory settings. I have since unlocked the bootloader and rooted. Now my nexus 7 only charges when it is turned off when I use my 2 Amp chargers. I don't understand. Here's the weirdest part, my bionic charger works on the nexus 7 when turned on. Yeah. 850 mAh. What the fek?
I tried charging my Note 3 with a Nexus 4 charging adapter, which is rated at 5V 1.2A both input and output. But according to the Galaxy Charging Current app, the Note 3 is charging at 1.2A while the screen is on and 1.8A when the screen is off. So does this mean that the app reading is incorrect? Because this would be a correct reading if I were using my 2A Samsung adapter but it wouldn't make sense for the Nexus 4 adapter. Or is the Nexus 4 charger actually providing 1.8A even though it says 1.2A on the charger?
I bought a powerbank aukey with quick charger. It hasn't a usb type C. Can I use this powerbank to charger the nexus without problems?
http://www.aukey.com/product/PB-T4 This is my powerBank
Yes you can it's what I use although when I first used it quick charge would work charge dead phone in an hour now 3 don't know if Android didn't like it having quick charge or that all three of my aukey chargers don't work even have used new certified cords.
