Is anyone else experiencing a buggy screen during charge. I used touch test to see what's going on during charge and it shows really jumpy and nonresponsive jumps.
I charge with a generic cable rather than stock, and I'm using a Motorola charger with a mini f to micro m adapter.
I'm not sure whether it's my phone or these wires. You guys get the same problems?
Sidenote: Charging my HTC Aria with these cables, theres no problems.
I noticed the phone is picky about chargers. I used a travel charger I bought for my blackberry and the screen was unresponsive. Used me blackberry branded charger and it worked fine.

It is your cable setup- there are posts on other forums. If you use the Moto cable and charger you will be fine.
I have the same problem. I'm using the moto cable and charger but using a dc to ac inverter in my car.
Hi,
I just got this charger for my Galaxy:
http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=260693816032&ssPageName=STRK:MEWNX:IT
I choosed this one because of the low price and 1A current, did not care about Iphone. The Galaxy seems to charge but touch display is not responding while charging. used a cheap ebay charger before that was working fine, also original charger and original I-Phone Charger from my wife does work. My wifes Iphone is charging well. what is wrong with it? thought USB is USB strange
Anyone else have any experiences they'd like to share using non-OEM chargers?
I use my HP TouchPad charger in my living room, as my HP Touchstone plugs into it usually. It charges the N7 at exactly the same rate as the OEM charger.
Just curious about others' experiences.
Oh....and is anyone else w/the HP TouchPad just completely spoiled regarding tablet prices? $250 seemed like a lot of money to pay, LOL.

I use this, it charges my iphone, ipad, ipod touch, samsung, and now my nexus. I have one for the car as well that is 1A/2.1A.
the blackberry playbook 1.8a charger works really well. indistinguishable from the supplied OEM. available for $16 bucks or so in retail packaging.
I've used the same charger for my Galaxy SII. Seemed to do the job well and just as quickly!
I have a few blackberry chargers one is a playbook one and some other android chargers.. they all work just fine.
I'd love to know if there are any portable chargers that will charge the Nexus 7 without being plugged into the wall, so, I can charge it when I'm laying in bed or something, I have portable USB chargers that I don't thing would work with the 7 The Duracell Powerhouse USB charger and the Sony Media CP-ELS USB Portable Charger with 2,000 mAh Li-Ion Battery, I use them interchangeably with my iPhone 4S and Playstation Vita.
Okay, I went through my "wall wart" drawer and tried 8 chargers and 9 cables. I can't find any pattern to the results
There was one cable (skinny black generic USB) that didn't work with charger, and one charger (from a Kingston Wi-Drive) that wouldn't work with any cable.
The best cable was a white mini-usb (that I used with a mini-micro dongle) that had come with my generic 5000 mAH backup battery; it worked with *everything* except the Wi-Drive charger. The best chargers were the OEM ASUS charger, and a generic small black cube (1A) labelled "KIN"; those worked with every cable except the skinny black dud.
The worst of the working chargers were an "Innergie" dual laptop/USB power supply, and the generic battery backup. Those only worked with that white cable.
Honorable mentions go to an old Motorola RAZR charger (used with a mini-micro dongle) and a small Samsung phone charger. Those have permanent cables, and both worked.
I couldn't pick up any pattern in terms of amp rating (obviously, the lower amp chargers will take longer). It seems to be "luck of the draw".
I've tried probably 4-5 different chargers including a Motorola wall charger plugged in the wall, and also plugged into a power inverter in my truck, a motorola car charger and an oem wall charger and have no issues with any of them.
iPad 3 charger compatibility
Can anyone confirm if N7 charges using the new iPad 10W charger? Mine only supports the charger that came with it. Does that mean that the usb port is broken and I need to replace it or is it the way all the units behave?

It charges using my iPad2 charger, which I think is the same charger as the new iPad?
The Nexus 7 does not show charging when plugged into any of my OEM/aftermarket Apple chargers.
It does not appear to matter whether I use the USB cable supplied by Asus, or a standard commodity micro USB cable.
There is evidence from other users that the tablet may be charging at the 1A rate even though the charge indicator stays off.
I have not personally confirmed this yet.
Im using the charger of my BlackBerry playbook! 5volts 2amp!
From 0% to 100% in less than 3 hours!

I bought 10 of the HP Touchpad chargers for $5 shipped a few weeks ago. They work perfect for the Nexus 7, same plug, 2AH charging..
I think you can still find them for $5 shipped @ hp.com
All my micro USB chargers work , from Nokia to BlackBerry to HTC all fab all charge the n7 OK

I've had one of those OEM/aftermarket Apple charges blow up on me (not shrapnel, it stayed in the plastic casing), so I wouldn't expect much from those anyway. Have you tried with any standard micro USB phone charger?
Chargers that work:
- Motorola Droid Pro (hard-wired micro USB). Rated at 800 mA but seems to charge almost as fast as the OEM.
- Kin One (Uses any USB cable). Rated at 1A, works with every USB cable I have (almost; there were a couple that didn't work with anything). These are available on-line for less than 10 bucks:
http://www.amazon.com/Sharp-Standard-Wall-Charger-CNR1002/dp/B005IY428Y
http://www.aftermarketcellular.com/ic/CNR1002.html
This is nice and compact; I'm going to order a couple of more to have as spares.
- Motoroloa RAZR (hard-wired mini-USB, used with mini-to-micro adapter). Rated at 500 mA. Works, but probably pretty slow.
- Samsung (from unknown phone; hard-wired micro-USB) rated at 750 mA. Didn't test charge time.
As an aside, I have a 5000 mAh backup battery that I've used with phones and my Nook color (http://www.amazon.com/5000mAh-External-Motorola-Blackberry-Nintendo/dp/B004P8E612). It works with the Nexus, but ONLY with the mini-USB cable that the Power Bank shipped with. Every other cable I've tried chokes. It's intended for an iPhone and puts 6.5V across the power pins (with no load; this is about the same as the Kin) and pulls the data pins to 3.4V. What's weird is that I can connect a 2-conductor (charge only) extension in series with the working cable, so that the data signal never reaches the Nexus. If I use a 2-conductor cable by itself, the Nexus doesn't charge.

When you say they work, are they showing as AC charging when you use them or are they just charging.
Go-to battery stats and it will say either
Charging (USB)
Or
Charging (AC)

Compatable car charger
It's really disappointing to know N7 is so picky about chargers. Can anyone report on a working small/short car USB charger that is compatible?
You might want to check that your vehicle can provide 2amps from its cigarette lighter plug. Normal only utility plugs can do that.

I just got a Nexus 7 a couple of days ago and of course I thought any USB charger would work. When it didn't charge on the charger I keep plugged in for all purpose charging, I resorted to Google to see what's up. I would love to have a single charger that works for everything. Having looked through many pages of discussion about this I did not see the answer to my question, whether the Nexus 7 charger will charge my other devices, phone, ASUS Transformer, etc, I know that the data pins on this charger are shorted, but does that prevent it from properly charging my phone, for example? Do the data pins being shorted affect it's ability as a general charger?
Especially for travel, having to carry a single charger would be preferred.
I ran into a similar problem with a friend's Nook Color, only there the problem seems to be a proprietary cable. Even in that case we discovered that a good charger (iPAD version) and a standard cable would work, just pretty slowly.
I may have missed the answer in my searching, and if so, please point me in the right direction. Thanks.

I haven't tried to search, but I have used my Nexus 7 charger to charge my Acer phone and my Logitech K800 keyboard and H600 headset.
I can't remember if I used the cable that came with the charger. I have a stack of micro USB connectors around. I try to bin any that are power only. Useless bit of wire. Maybe that is why things are amiss at your end.
I've charged my friends HTC X One with the Nexus charger. Worked fine.
Haven't even taken the nexus charger out of the box. Been using my Samsung chargers from my SII with no issues. Hope I don't have a problem using the auto charger.
BTW, a search would have led you to this thread.

Guessing the charger you're trying to use isn't providing edd enough current... The standard charger puts out 2A (2000mA) when standard USB is 500mA and many chargers are 1A... That said no charger/cable combo I've tried has failed to charge (just sometimes it's glacially slow if its a 0.5A/1A charger)
I just found out that My old Galaxy S charger has only 0.7A while the N4 charger is 1.2A
If I use the old charger for N4, it should be slower..
But is it okay to use this new charger for my old phone or bluetooth earpiece?
I don't want to bring two charger out but I may need to charge different devices
Also, is the USB cable came with N4 a special one that can deal with 1.2A,
or every USB cable is fine for that?

Not sure if it's recommended, but I've done it without issue.
Slightly off-topic: If anyone has a lead on some cheap 1.2A chargers, please post a link. Bought some low amperage ones off DX but I'll be dead before they finish charging the phone.

As long as the voltages are the same, which they probably are (5V is standard for cell phone chargers), you'll be perfectly fine using the 1.2A charger on the 0.7A phone. Your old phone will only pull the amount of amps that it can use - it won't pull more than that. What you want to be careful of is charging a phone with a charger that puts out more volts than the phone can handle - this is where you can fry your phone.
As for your second point, I'm pretty sure that any USB cable will be fine.
