Much to my amazement I discovered that the charger for my new Sony RX100 pocket camera also charges the Nexus 7!
I don't know about you, but the assortment of connections, adapters, power cables and chargers can be intimidating to keep straight.
Maybe there are others that would work too, but the accident of plugging in the wrong charger amazed me.
Nexus 7 just uses a standard microUSB cable so any cable from a modern device made by a company that isn't obsessed with proprietary chargers should work.
You're right on, I agree
Pawnty -
It's not that simple. While MicroUSB is indeed standard, not all cables will work on all devices. A friend of mine has a Nexus 7, and it is very picky about what cables and power sources it will charge from. I just got a Sony HX20V and am running into the same problem. It will not charge if I use the iGo AC charger that I have been using for my phones for the last 2 years, my retractable USB-MicroUSB cable, or my AT&T-branded car charger. So far, it has only charged with the cables that came with my Captivate and Galaxy Nexus, plugged into a computer or their corresponding AC adaptor.

I can confirm the iSound Power Max (18,000 mah) battery does not work.
Zagg Sparq 2.0 (6,000 mah) works if you're not using the optimized port, and the Solio Bolt solar charger (2,200 mah) works as well.
Looking for alternatives too as my 6600mah Lenmar I've been using for my phone is a no go even though it has a 2.1amp. charges my kids ipad no problem.

Just be aware that it isn't always the portable charger that doesn't work but it could be the cable. Based on the few threads already discussing which aftermarket chargers and car chargers work, you can see a pretty strange pattern of some cables working with a charging unit while others don't.
Just an example, I was testing my 2A Griffin Car Charger last night and it didn't work with the stock cable (Cable that came with the N7). But once I tried it with the cable that came with my Portable Charger, it worked.
My New Trent IMP1000 works with the cable that came with it (retractable with interchangeable micro/mini tips) but not with other cables. That cable also works with several other chargers where other cables don't.
Zagg Sparq
I use this one: http://www.zagg.com/accessories/zaggsparq.php Right now they are giving free pair of 50 dollar headphones with it that are really nice!
I have a New Trent IMP500 and an Energizer PowertoGo. Both will only work if I use the cables and tips that were supplied with the power source. If the screen is on it says charging but the battery level seems to stay the same; if the the screen is off it charged 3% (from 83% to 86%) in 10 minutes - using the New Trent. I have not tested the Energizer yet.

The ZaggSparq is a piece of crap - it suffers from really bad battery drain. Unless you charge it weekly, it'll almost always be empty by the time you need it. I fell for the first generation, which was even worse. Then when they wouldn't replace it, I made the mistake of getting the new version - which STILL has the draining problem.
Get something better - like an Anker.
I picked up the New Trent 12000mah 2a portable power supply.
http://www.amazon.com/New-Trent-Thunderbolt-Blackberry-IMP120D/dp/B003ZBZ64Q
It comes with 2 cables:
-a standard USB to Micro USB (or whatever they call them that come with 99% of devices including the N7)
-what they call a Galaxy Adapter which is nothing more than a 2-3 inch USB extension that you can plug any USB cable in to including an iPad cable.
When i plugged the stock N7 cable in to the power supply (2a outlet) it didn't show as charging.
When i plugged in the standard USB cable that came with the power supply, again it didn't show as charging.
When i plugged in the stock N7 cable to the "galaxy adapter" and then in to the power supply, it did show as charging. Strange that the adapter made a difference but whatever at least it works.
When i plugged in another cable with multiple tips that came with my other Anker Portable charger, that worked too. No adapter required this time.
I did a test and confirmed that with the combinations that work, it is charging at the same rate as the stock wall charger.
The Anker 8000mAh I have charges the Nexus 7 at 2A. You have to use the Anker cable though.
New trent came in before anyone else, mine has been working for a good 3 years.

I like my Sparq a lot. Had it maybe 4 months. Got it on the recommendation of several friends who have all loved theirs. And frequently they are only 50 bucks.
The only issue I have is as stated in the first post, it doesn't work in the 2.1a port. But I haven't found any of the 2.1a chargers I've tried work.
Charging my Nexus 7 with a 3m USB extension cable that I had lying around seemed to take forever (although I was using the charger from a Galaxy Tab, but I suspect the same applies with the Asus charger). So I thought maybe the cable wasn't very good and I start looking for different extension cables on the web and I find out that there are actually some ACTIVE extension cables that supposedly carry the signal without loss for as long as 5m. What I'm not sure about is if this is actually true because the store clerk I talked to about this particular cable recommended this cable to me, and said I needed an active cable, but he didn't seem very confident on the matter. I told him I needed it for charging, not for data transmission though. Anyway, just wondering what you guys think about these active cables, before I spend a lot of money on it?
This just reminds me of someone at Best Buy telling you that you need monster cable hdmi cables. (quicktip: hdmi is digital, monster cable does nothing special but charge 80 bucks)
I'm assuming it was your other charger, and not the cord. You want to use the brick that came with it to charge. It puts out at 2amps, anything less will take longer to charge.
The other charger also outputs 2A and I used it for a while with the OEM cable (short one, just like Asus') that came with it and the tablet charged as fast as with the Asus OEM charger. I am now using the Asus charger all the time, with the Asus cable. The only combination I didn't try was the Asus charger and the exension cable but I'm pretty sure it won't work either. So, no, I don't think it's the Samsung charger's fault. My Galaxy Tab used to charge completely in about 10 hours when I was using that same extension cable but back then I thought it was the tablet's fault. It never crossed my mind that the extension cable could be the culprit, until now..
I have this Griffin Dual USB PowerJolt Car Charger and its been working perfectly on all my devices, Playbook, Blackberry 9900, Samsung Galaxy S3, iPhone 3G, iPad 2 and many others but for some reason, this charger just don't want to work with my Nexus 7. I don't know why its so picky and wondering if you guys could help me identify the problem and preferably with a good working solution.
I tried opening it up and follow the advice from http://www.amazon.com/gp/customer-m...m_ciu_pdp_images_0?ie=UTF8&index=0&isremote=0. Both pins are already been soldered together but the Nexus still isn't charging!!
This makes me wonder where's the USB standard? How are some device / chargers so picky? What did the manufacturers do to prevent charging on other devices or charging through a non compatible charger?

You may get flamed for this question because chargers have been discussed a LOT in this particular forum. It seems that none of the discussions show up on the first page at the moment.

Thanks a lot. I did read up all the posting regarding the USB charging issue on the N7 but I still can't find the answers. I read about people having the Griffin PowerJolt and not able to charge their device.
After downloading the Battery Monitor Widget and plugging to my Griffin PowerJolt (short D+, D-), the device is charging (estimate: 384mA) but still not showing as charging. It shows Discharging and Unplugged. I don't think its the USB cable since the cable works on my PC.
So what causes this issue?

It doesn't matter why, just that your Griffin does not do a good job of charging. If you want more either buy oem or any charger designed to work with Samsung, those devices should work better.

I guess I still blame on the N7 for being so "picky" since the Griffin USB charger charges ALL devices, including iPad, Playbook, Samsung S3, iPhone and Blackberry but just not N7.

Yep, the Nexus 7 is picky. No question about it. But your chargert *does* charge your Nexus 7, the Nexus just doesn't indicate it's charging.
Personally, I bought two KMASHI chargers from Amazon. It's a 5V 2A charger and it works great. Charges at greater than 1Ah and the N7 indicates it's charging. Won't charge an iPad but it works for me. The one I bought is http://www.amazon.com/gp/product/B008XQYH1G but it shows as unavailable now. I suspect the other KMASHI chargers will work the same, though.

It charges it but its slow. Being rated at 1A, its can only charge at 300mA+ so its rather disappointing plus the charging isn't consistent. Sometimes when I plug in, it will charge, sometimes not so its another disappointment. But I guess I quickly adapt it and don't bother too much now.
I can still use my in car Head Unit with a build in USB port. At least I am getting 400mA+ and it shows as charging so I am ok

Ive been recommending this Sprint 2A dual usb charger to everyone. Its a OEM charger so you can expect a high quality product that works as it should and it puts out the required juice to rapidly charge the N7. It also has the added benefit of doubling as a wall charger. Ive had mines for about a week so I can confirm it does indeed work! http://www.ebay.com/itm/130712043019?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_1459wt_1399
Hey All.. I looked forever to find a solution. The Targus 2A car charger has a small (3") adapter cable that comes with it purportedly for Galaxy Tab. That little cable with the data wires shorted on the device end allows the N7 to be charged from ANY 2A car charger. I'm using the adapter with a Scosche dual 2.1 Amp Car Charger
Adapter picture
Targus Charger
Edit: I just built a usb cable with the data wires shorted on the Nexus end (cut, strip, short micro usb end green and white, remake connections red to red and black to black, insulate splices individually, wrap all in electrical tape or heat shrink for strength and beauty) and it works with all chargers. Took about 20 minutes.
Could someone recommend any good supplier of USB to microUSB cable that can handle 2 amps of charging the note 2? Other than the cable I got from Samsung, all my cable charge super slow my note 2 (from the original charger).
Thanks

interested in this one too! also, a 6ft cable if available.
TIA
I'd be interested, also!
I purchased one of those 6 foot cable extensions and just plugged the stock cable into it and the extension portion into the stock charger. Works like charm.

No no not saying they wont work....its the performance aspects of cables.
kindle cable contained in link is 5-6ft long , allows usb sync , built for 2amp current flow and user reviews are solid which = Good quality.
A little explanation on why I'm buying new cable,
My stock is defective micro connection wasn't sure easily falling out of device.
I took it to ATT service center showed them what was up and they ordered replacement cables that sucked.
1st Rcable was too short -Samsung was only 3ft long.
2nd Rcable didn't sync to pc - Off the wall brand 6 ft long.
From that point I broke out utility knife modified stock cable cutting some plastic off sleeve on micro end.
Connections now sure but cable looks beat up so replacement was needed.
Well I received my Amazon Kindle replacement cable today
Kindle Cable is of good quality , connections are firm much better then stock oem that came with device.
I highly recommend it.

Yes, from my previous post:
I've struggled with a variety of the longer, non-OEM micro USB cables - the Amazon Basics, cables from Monoprice, etc. I had problems with all of them, either not providing enough current, or just flaking out within a short time. At one point I thought my phone (EVO 4G) had a problem with the micro USB jack (it didn't). Then one day I found a great cable on Amazon:
Search Amazon "Mediabridge - USB 2.0 A-Male to Micro-B Cable (6 Feet)"
I've been using this cable for several years now, and it has proven to be very durable (I've run over it with my office chair a number of times), and has always provided the full current of the charger I am using with no issues at all. I purchased another one recently to use in another location, and the quality is the same. I've been using these cables with all of my phones, and currently with the Note II.
I'm using this one from Monoprice, with the standard OEM Samsung wall / desk charger that came with the Note II:
http://www.monoprice.com/products/p...=10303&cs_id=1030307&p_id=5458&seq=1&format=2
It's six feet long, and is a pretty thick cable. I used it today for the first time to charge my new Note II. Coupled with the standard Samsung charger, it charged my Note II from 12 % to 100% in two hours, thirty one minutes -- and that included charging during two incoming phone calls that each lasted about 10 minutes.

If my calculations are correct that's putting about 1120 Ma per hour into your phone.
I wonder if it would charge that fast on usb and have data too?
I also wonder how that compares to the stock USB cable that came with our charger.

Good questions. I was wondering the same things, particularly as the Monoprice cable is double the length of the stock one. At some point, I'll try both charging from my laptop with the Monoprice cable, and switching out and using the stock USB cable, for comparison purposes. My problem (well, not REALLY a problem at all!) is that my battery seems to be lasting around 27 hours, so it may be a while before I can get around to doing this!

My stock usb cable that came with my Samsung charger shows charging on USB, even though it's plugged into the wall.
Conversely, put my note on my 2 amp car charger and the note says charging on AC.
Something is not right with the stock setup. Sure it charges but it should read charging on AC if it's on AC.
Just did a test. Found a usb cable from another device and plugged that into the Samsung stock charger. Now it reads "charging on AC."
I used that same cable and USB on my desktop. My note said charging on USB.
I think the cable was the bottle neck on the charger and the usb port on the desktop is not putting out enough power to make the Note believe its on AC.
USB is USB as far as our desktop/ Note goes, but if you are using AC, then the cable becomes more important if you want the fastest charge. What's apparent is we didn't get a real charging cable with our Note II. .

So far, I haven't had any problems with my stock Samsung USB cable. You can always try the Monoprice cable I mentioned in a prior post. Also, I've read on these boards that it sometimes helps to try different USB ports on your computer, and that it can actually make a difference in charging.
Interesting topic I have been wondering about myself. The cable I got with my Note 2 is not good. The connector, when attached, is easy to move aside, does not hold in place and the sad thing is, it is original manufacturer cable.
I used several different cables and found out that the problem is the height (length) of the micro USB connector, which protrudes from the connector's plastic cover. The other thing I found is that standard Samsung cable, delivered with the phone is few fractions of millimeter shorter than any other cable I compared it to, and suffers from it.
Amazon basics cable I ordered recently might have the connector metal only barely longer, but holds much better (in fact it fits tightly and feels very well fixed in the socket). Contrary to some, I have not observed any problem when charging the phone with this cable and original charger. Maybe the newer cables are already adapted to the chargers as well.
The fact that the norm is not always the norm is also proved by original Samsung MHL adapter (with HDMI out). This has "micro USB" connector (here it is 11 pin though) which is roughly 1-2 mm longer than the one on supplied charger cable. This one gets "all way down" into the hole and still does not even touch the case with its plastic part (there might be ~ 1mm space between the plastic of connector and Note 2 case).
Now, when I look at potential micro USB cable for Note 2 I always check the length of micro USB metal part. It must be longer than original cable from Samsung, otherwise it will have flimsy connection.
Length
I try and use a shorter cable as the longer they get the more power you loose. I use a 6" inch usb A to B Micro. I love this cable because my phone can sit right next to my computer and its getting the max power.
i get them at cableforge.com
use this coupon it always works for me G5WJXH4F22MN

Hi all, not sure if this is already well known in the community, but I thought I'd post it anyway in case someone doesn't know:
I've owned an OP3 for a few years and as such I've collected a few Dash-chargers. As most people who switch brands I now have a mix of cables, chargers etc. and I've been using them kind of agnostically, assuming that the only thing I'll ever lose is the "fast charging" capability.
Long story short, it turns out that both my Dash chargers will only charge my Samsung phone with "USB-speed" regardless of what cable is used. If I move the phone with the same cable over to an iPhone charger (the smaller ones), it AC charges like expected. This also works as expected with an old Asus android charger (with a OP3 USB-C cable).
So, if you have Dash chargers lying around and you assume they work just fine with other phones, you should verify if this is actually true by using an app like Ampere. What I've found is that they never go beyond USB charging, so they're more or less useless for anything but OP phones.
What's your experiences?
I don't think it's a good idea to charge other devices with your Dash Charger. I did that with my friends OP2 and the cable didn't Dash Charge my 3T anymore. Luckily I had a spare cable that came in with my Dash Car Charger.
