I was wondering if these docks had enough juice to charge our N7 tablets? I have the AS851 that I have been using with my Galaxy Nexus but when I put the N7 on there it doesn't charge it.
bump in case any of you guys are in the same situation

I have the AS351and that does not charge the Nexus 7 but works fine with the Galaxy nexus. Very disappointing.
You might be right about the charging capacity. I just noticed the standard Asus brick is 2amps!

I read the specs on the docks and they push out 2A from both the micro-usb and usb port on the back. No idea why it doesn't charge the N7. The microUSB is long enough..it gives a good click when the N7 sits on it. I haven't tried a charging cable only to connect. I don't have one. All mine are data-sync/charging cables.
I don't know if any of the custom kernels for the N7 have "fast charging" as an option/enabled, but I wonder if that would help?

Hi did the N7 actually not charge, or did it simply not say it was charging?
There's a thread on XDA which compares cables/chargers, and unless the USB data pins are connected together the N7 does not show the charging symbol, but would still charge (possibly at a slower rate).
EDIT- ok...not sure if y'all have found this out but the fidelio does in fact charge the N7, just doesn't show a charging icon. And it charges it soooooo slooooowww :-/ It's been on the fidelio for 1/2 hour with only 5% increase. That makes me nervous, so off the fidelio it comes.
Have we determined if the fidelio does in fact charge the N7 but doesn't show it as charging?
my nexus 7 tablet just wont charge, im using the stock plug and usb cable provided with the nexus 7. It it on and says charging but battery percentage doesnt increase. As of now, it is on 0% and has been for the past 5 hours. I've also tried other usb cables and a motorola milestone charger/cable and still no luck, please help me.
thanks
I had the same problem. Check the charging unit and make sure the two sections have clicked together.

thanks for the info, yep its in there and clicked together, still not charging properly, i think its a dead battery issue
Have you tried using a different charger or tried charging through your PC to eliminate potential problems with the plug and cable? Just a thought.

Try to jiggle the cable in certain directions such as up down left right and see if it starts to charge. If it doesn't, return the sucker.

I have found the N7 is picky with cables' the default one that comes with it works fine but doesn't seem to want to charge through my car charger.
My epic4g cable doesn't work and neither do any of my other USB cables.
Same with the charger, it has to have a dedicated live connection and no USB splitters with multiple ports.
I need like a good 4-5' USB cable to use tablet comfortably while charging.

I am now having similar problem on 16gig. It will not charge from the power adapter at all, but will charge from a PC using same cable.
Same behavior on my alternate cable that I use for phone.

My car charger doesn't work either but my computer/tv/printer/tivo/wall/everything else works just fine... it must be a voltage issue with the car charger.
I remember reading that the charging issue some of you guys r having is a confirmed hardware problem, due to poor quality control. Asus was in such a rush to get the first few batches out that certain faults made it into a select number of batches. Other people who have had this hardware problem either could only use the Asus adapter, or that might not even work. You should try to get it replaced by your seller. I'll post the source in the morning if everyone's too lazy to Google.
Cheers
possible fix
I've read on other forums that it is the usb port. I my experience it is a intermittent connectivity or the wall wort isn't putting out enough amps. I bought an iGo Green for the iPad, put the tablet in Airplane mode and it will work fine while using it. Last night I shut it all the way down, let it charge overnight and woke up with a full battery.
Seems like only high output chargers work. All my 2.1A chargers work with Nexus 7, but lower output ones do not charge even when Nexus 7 says it's charging.

Just for the hell of it...... pry the back cover off and make sure the battery is firmly plugged in. This happened to mine and now all is good

My 8GB arrived Monday , 1/2 charged pluged in to the 2A charger it says its charging but the battery just drops. Turned off and left overnight and its still no more than 20% charged.
I need to find an app that shows charging
check output of charger, check cables, check charge on phone vs tab then send back to Google for a replacement grrrr
I have the same problem, how do I fix? I have the 16 gb version.
The N7 seems to be having a lot of problems with charging. A couple times when my battery has been completely dead, I have had a tough time getting it to begin the charging process. One time I watched it begin to charge, then boot up, stay on for about 20 seconds, turn off, and then not charge. I have no idea what's going on. I always eventually get it to work, but something doesn't seem right.
Remedy
Google Play telephone support had be factory reset my Nexus 7 8GB. After the reset, the battery began charging. A major nuisance having to redownload everything, but it does work. Good luck

I am not sure if anyone else is experiencing this but I am seeing that i'll charge my phone for somewhere between 5-8 hours using the original wall charger and cable but it will not fully charge. It gets to about 70-80%. Is this happening to anyone else?
Any other details? Rooted? ROM?
My phone fully charges from 10% to 100% in about 2 hours or less
Sent from my Nexus 4 using xda app-developers app
5-8 hours is definitely not normal. It fully charges from 0 to 100% in 3h 45min Max and even that is a little bit of a stretch. For me its more like 3hours.

Check your chaging status. If it says USB, thats your problem. Without further knowledge of your setup, I cannot advise you any further
Just happened to me, plugged into original charger before going to sleep, woke up and it shows only 80%. Plugged into Samsung charger, now up to 90% in 20 minutes.

Stock everything. It's happened about 4 nights now.
I find that sometimes my stock charger detects as USB instead of AC. You can see if it is charging that way in the battery details in the settings. When it is stuck on USB it is way slower.
Sent from my Nexus 4 using xda app-developers app
Yeah and if you want it to charge a little bit more faster you turn off the device
Check about phone, make sure it says Charging (AC) and not Charging (USB). If it's USB then thats the reason why, use another charger.
My stock charger that came with N4 went to USB but then for some reason, after I replugged it, it went to AC and has been AC ever since.

I was having a problem where mine, with the charger that came with it would charge very slowly, once overnight only got to 80% in ~8 he's i watched it and sometimes would not even show charging on the lock screen. I switched to my HTC one s charger and it is charging with great speed. Issue with these chargers?

did your HTC One S have an adaptor like the Nexus 4 or any other phone now a days... I think thats the probllem. having an adaptor from USB to AC PLUG messes with these phones. Like I said before, above post.. buy an LG AC Wall Charger.. works great.

Wow, glad I found this thread. I was wondering what the cause of this was, as well. I've been using my GNex charger since it switched over.
Hi I recently bought a Nexus 4 16GB from Google Play in the UK. It's been working fine but in the last few days when I connect my phone with the official charger (the one that came in the box) the touchscreen begins to act weird and buggy. More specifically it becomes less sensitive and doesn't function properly. I can scroll down on the app drawer with no problem but scrolling up is extremely slow- its like its scrolling through syrup, same on homescreen. Thinking this was an app or kernel problem I removed an app I thought was causing the issue and reverted kernel back to normal but the problem persists. I now think it may have something to do with the charger being faulty as I am now charging my Nexus 4 with the charger that came with my Nexus 7 and no problems with touchscreen responsiveness or interaction.
Has anyone else had issues with this? as I've seen people have trouble with non standard chargers but I'm using the official one.
Would Google be able to exchange just the charger and not the whole phone package? And is it okay to use my Nexus 7 charger for my Nexus 4?

Yes you can use the Nexus 7 charger. In fact, you can use any Micro usb charger cable to charge your phone. The phone will take in the amount of power it needs. It shouldn't be an issue.
Anyone know what could be causing the touch screen issues when charging. That's what confuses me the most. Could it have something to do with the charger heating up or being faulty?
Thanks for the tip about using my Nexus 7 charger instead.

I know that with some of my older phones, when charging from an inverter that did not stabilize it's output voltage, my touchscreen would do the described. Maybe the charger fluctuates in voltage slightly... This was on my old iPhone 3GS, I can't remember if my Atrix did it... It might not do that on the Nexus

It would probably be something with the charger output then. Maybe it has to do with amperage output rather then voltage, I know that some people had issues with the stock charger outputing less amperage sometimes making the phone drop to USB mode. IMO the stock charger kinda sucks and its better to just buy another charger and keep the stock one for backup or something
Hi so my nexus 4 is charging very slowy, I've this phone for 1 year and I don't know what's happening...Also that might explain (why but)...... if its because of my charger or what. But I need help like I'm just wondering why this is happening? Thanks. Also I don't know if this is happening because of the 4.4 update or something lol?

Apparently something is wrong if you see it charging slowly becoming ever since day one, I've felt that it charges really slow!
The only way to test your theory is to downgrade and see what happens. (as far as the upgrade is concerned)
If you have another charger, obviously that would help as well to see if the n4 charger is shot.

I have recently started seeing this problem as well. I even tired a different kernel thinking maybe that would solve it, but to no avail.
I will try with a different charger and see if that would help.

When you go to the battery history (from quick settings for example), does it show (constantly or alternating) USB charging when lugged to wall socket? When i had this, i changed my USB charging cable (the charger is ok but the cable died quickly)
Charging slow is usually due to the charger, try another one that is at least 1A output (original charger is 1.2). Nokia ac-10x is perfect and pretty cheap.
Other causes can be bad charging port or sometimes even a battery drain caused by software.
Whenever you plug in the charger make sure that your Phone shows "Charging (AC)" in your battery setting. If it says "Charging (USB)" then unplug and replug it again. Keep doing until it shows "Charging (AC)"...... On USB charging it charges at 500mA which is half the charging speed of AC charging. I had this issue and I am doing the same to charge it quickly. It doesn't take more than 2h 15mins to charge.
