I haven't seen a thread that addresses this specifically:
After reading the threads in this section, it seems that the consensus is that the "fast charging" aspect of the NC is based on extra pins in the special NC cable. When connected to any charger with 1.9amps or greater, you will get the fast charge.
My experience is different.
Using the OEM NC cable:
1. Connected to OEM charger, stock ROM - settings say charging, flashes an icon with charging percent on connection and removal
2. Connected to OEM charger, CM7 - settings say Charging (AC).
3. Connected to 2.1 and 2.0 amp chargers, stock - settings say Not Charging.
4. Connected to 2.1 and 2.0 amp chargers, CM7 - settings say Charging (USB)
Using the generic microusb cables (2 or 3 tried):
1. Connected to OEM charger, stock ROM - Can't remember, but not going back to stock!
2. Connected to OEM charger, CM7 - settings say Charging (AC).
3. Connected to 2.1 and 2.0 amp chargers, stock - settings say Not Charging.
4. Connected to 2.1 and 2.0 amp chargers, CM7 - settings say Charging (USB)
This seems to imply that the OEM charger is required to really use the extra pins in the NC OEM cable. Can anyone test and confirm this?

The nook charger puts out almost 2A of power, where normal usb chargers and ports on computer only put out 500mA. The cable that the nook comes with has some terminations in it that allow the nook to tell when it is connected to the nook charger. It will charge at a much faster rate when using the combination of the charger and cable that came with the nook. Replace either the cable or the charger with anything else and you get low power charging mode which is very slow.
Nook Charger
I keep seeing reports of people getting a fast charge using various other equipment, as long as the chargers are rated >= 1.9A.
Can anyone confirm or deny this? Any testing?
As long as a charger puts out near 2A of current, it should work. The charger itself is just a four pin USB charger. The cable itself... lots of pins in the connector to the NC.

That's what everyone's been saying, but it doesn't work that way in my testing. I have tried 3rd party chargers that output 2.0 and 2.1A, using the OEM cable. None of them are recognized as an AC charger. If we knew how the NC knows when it's connected to the original charger, we could find a way to modify something available at WalMart to quick charge our NC's. There's plenty of Ipad chargers (2.1A) available. The one I have doesn't work, though.
Alan
Update to my previous post:
When I got home from work I tested my ipad charger (2.1A) with the nook color cable and it seemed to act like the nook charger. I did not think any charger but the nc one would work, but it seems it does.
I am jealous. My Ipad charger (OEM) paired with the nook cable shows Charging (USB) under Settings --->About Tablet--->Status. I would love know how to get it to say Charging (AC) .

Keep your eyes open people...as soon as I return to work and have extra cash I plan on ordering and tearing down a charger and cable. Many have noticed poor quality in the chargers..I'm gonna try to engineer an open DIY charger and cable replacement with better filtering components. Hopefully will be creating a thread with full details in 3 weeks...

YAY! I have my soldering station warming up.
Cheers,

yep, this is overdue...plugged in last night...almost burned my hand after an hour of charging. I keep my charger by the bed and the hum is just annoying when I'm feeling a bit restless.
Is there a way to identify problem chargers?
There must be some real inconsistency in the charger build quality. I've never noticed mine gets more than just a tiny bit warm and no humming. I wonder if there was a bad lot of them made? I was trying to look at the charger to see if there is a lot # or such, but can't tell what half the darned thing says. I'm posting a pic of the text on my charger in the hopes we can figure out if there is some way to identify problem chargers.
Edit: My nc came from WalMart.
Well there is a difference in the markings at least...The area circled in red...On mine it is R1101.
Still made in China
Edit: BTW my unit came from Walmart. Not sure if there would be any accounting for things like that.

Sounds great. The simple tests I have done have yielded more quetions then answers.
Looking forward to your data.
ive noticed i cant transfer data on anything other than the nook cable.
The NC cable is special. It wont fit other devices.
described over here....

Charging the NC on a regular microUSB means much longer time.

Yeah, this much is well known...my plan is to find out if there are "brains" in the charger or if it's just a high amp USB adapter. If the latter is true( which I suspect), then it's easy peasy to make a high power port( or just buy a quality one). If it has special circuitry...then I get to try and replicate it( with better parts) and release the plans so others can make DIY replacements.
Edit: I'm willing to bet that the extra pins in the cable are just to increase contact surface...to handle the higher amperage.

That is totally wrong, since other cables WILL transfer data just fine. I use an LG Micro USB cable from my old dare, and am able to ADB push, install, etc just fine.
As it is, the large end of the Nook's USB cable is normal; this means that if the nook is communicating, it is doing so over the standard USB data ports, and not through some special connection. Keep in mind that some of the extra pins from the micro side are for the status light that is built in.
Hmm R1102 here showing 1.9A output
I'm curious.. some people have talked about warranty replacements. What R versions are those?

Hmm....hadn't thought of that...that charger almost has to be dumb...just higher output...the smarts all have to be in the USB/power management chip in the nook. Those extra pins must be for the led and maybe a few for handling the higher amperage. Need to check out the spec sheet for that chip again...
Sent from my NookColor using XDA Premium App
Why does it HAVE to be dumb? I mean, the charger needs to do nothing more than respond to a ping, saying "Hey, im a Nook charger, take me for a 1.9A ride!". I guess that makes it dumb, but no reason said technology won't be in the charger.
Hi,
I have bought an usb cable on the market and i found it very slow to charge the phone compared to the lg cable. I found out that maybe it was because some usb output 1A, some 500ma, some 200ma.
Each time I ask a seller how much intensity the usb output, they don't know. How I am supposed to know this if I don't have a multimeter? (and a computer + 2 filaments each time I am in the market)
Thank you.
It depends on the charger, not the cable. Computer usb output is always 500ma
Sent from my LG-P990 using XDA App
Unless you have a new motherboard with a dedicated charging port, the max you can get over USB is 500mA.
Well well, this night I checked again if I was wrong and no.
Indeed, I charged my phone which was at 2%. It raised to around 70% in 7 hours! I used a market usb charger, in my pc usb port. And the phone was off (android not started).
Now, if I use my LG stock usb in the same usb port, I can charge at least 30% in 1~2 hours, phone with android started.
Moreover, I googled and found out that if you hacked you usb cable, something with the data pin thing, you can have an 1A current. So the 500mA is a specification limit, but in practice you can have more I think.
Or... maybe my phone displayed a wrong battery status? How can I know if I buy a cable, that it charges fast?
NONONONONONO!!!!
Do not try and draw more than 500mA from your USB port, this is a terrible idea, stop now.
I am not wanting to draw more than 500 mA, thank you for that. I know that it may break my usb card or something like that. No I just want to get an usb that charges my phone in one night. I have one cable that does that, one that doesn't. It means either:
case A:
Lg usb cable = 500 mA
cheap usb cable = 200mA
case B:
Lg usb cable = 1A
cheap usb cable = 500mA
case C:
my computer likes the Lg usb and gives it more current.
Yes, but turning your cable into a charge only cable (shorting the data pins) will make the phone think it's on AC when it's plugged into a USB port and try to draw 1A.
Well it is possible that you got lousy quality cable, meaning it has high resistance (bad copper quality, maybe it even isn't copper, who knows) and/or very thin wires inside, which makes it hard to transfer high current. Although 0,5 A is not really "high". This needs some measuring, but if you don't have multimeter and some practice with that, you're better of with new cable
I can recommend this one, charging with it right now: http://www.dealextreme.com/p/designer-s-micro-usb-data-cable-for-htc-g7-120cm-length-48714 - there are cheaper ones but wouldn't recommend. While you're at it, DX has some micro HDMI cables too
Out of curiosity, if your main concern is to charge your phone in 1 night then why not....
A. Use the supplied cable with your computer.
Or....
B. Use the supplied AC adapter.
Now for your question:
In my experience cheap cables typically don't work as well for either charging or data throughput as their higher quality counterparts. I have cut a few of them for various projects and cheap cables usually have cheap, high gauge wire (higher gauge wire means smaller diameter for anyone not familiar with the AWG standard.) The smaller diameter translates into higher resistance and ultimately lower current through the cable. That is probably why your phone charges slowly on the cheap cable.
As others have said its not recommended to modify the cable to draw more current. Best case it could cause something to stop working like the port on your computer or phone or the cable its self. Worst case it could cause an electrical fire.
If you want to test my hypothesis as well as another cable before you buy it then get a multimeter and test the resistance. I never cared enough to test my theory so it isn't confirmed, just a very probable theory (this is the same reason why really cheap jumper cables take a long time to jump start your car when higher quality ones generally let you start the car right away.) I would test for you on some usb cables I have laying around but my multimeter is burried somewhere in a box at the moment from when I moved.

Lol you posted this as I was typing my reply.
At the end of the day a high quality USB cable is not much more expensive than a low quality one. Its usually best to spend a little more for one that works as it should.
Edit* I looked back at the time stamp and I guess I just overlooked your post.

In DX case, there is 1$ difference between cheaper and ok quality cable. Not really worth to even think about it . I've got 2 of those, very satisfied.
Yesterday I forgot to charge my LG, it was completely empty and turned off when I woke up. Plugged in to PC via USB extender cable and it was charged to 50% in 3 hours while turned on, did some surfing, emails 'n stuff.

There is a telling that says: "You get what you pay for"
The only reasons I can think of is that ether the cables contacts are broke, its poorly soldiered, and or they have used a extremely cheap metal inside it to make it cheaper. As most should have learned in school all electricity goes by V=R*I (almost all). By looking on that we easily see that the only possible way for it to be as you describe it is that the other cable have a lot more of resistance that "eats" up the electrical current.
Conclusion: Don't buy the cheapest crap you find you'll end up regretting it any way.
I bought what i thought were a couple higher quality universal chargers. They charge my razr fast but won't charge my nexus 7 at all. I have one of the chargers pulled apart but before I do any soldering I want to make sure -- if I cross the 2 data points will it work?
Well I couldn't wait 10 minutes so I tried. Answer: no. Wtf?
Can anyone tell me how to hack these chargers to make them work? Is there a resistor I need to remove?
Isn't it more likely to be a software thing?
With my samsung Tab 7.7 i couldn't charge it using my ipad charger until a Dev modded the software on the tablet.
are they 2Amp chargers? most universal chargers are only 1Amp
Well whatever the problem is, I want to charge my tablet in more than one place, I want to charge it faster than the 16 hours generic chargers are taking, and I don't want to pay $30 for OEM chargers.
If your tablet is taking 16 hours to fully charge, return it. I can drain mine after heavy use of the day and its still fully charged in under 6 hours.

@soldeus: There's nothing wrong with my tablet. The OEM charger works fine and some of my generic chargers work, they just don't have the current. (See below)
@vivan: They are 1A chargers, but they should still work. They don't charge at all. The 500ma Blackberry charger I'm using here at work will charge it in about 8 hours.
Ironically the move to almost-universal micro usb chargers has made the market for them even worse. Now, instead of having to buy a new charger every time you buy a new phone, you have to buy a dozen different chargers till you find one that actually works. Like I said, I didn't try to cheap out. I got a high quality charger.

The OEM charger is 2A for a reason. Because the tablet uses more power, it needs more current to charge at a fast pace.
Your generic 1A chargers are probably just enough to keep the tablet powered on, without draining (or charging) the battery.
If you can find a 2A universal charger, it should work just like the OEM one.

No, my 1A chargers are doing NOTHING at all. I plug it in and the charging icon doesn't come on. Reviews have tested these chargers at about 950ma and as I said, my 500ma Blackberry charger isn't too bad.. It's not lack of power, it's something else.
My guess is it has whatever resistor it needs to make it an "ipad" charger. And the vast majority of 2A chargers will, too.
So.. back to my original question: what do I need to do to make this charger charge my tablet? I KNOW it's possible. I just need to find the guy who can tell me how.
I also need a charger for my car, my usb power adapter in the car does not work, need to know what car charger will work as this tablet is supposed to be my car stereo replacement, sucks having to bring your stereo in to charge it and hope it lasts till you get done work
I bought the Scosche dual 10 Watt car charger, isn't here yet though. It does say it wont charge the Samsung tablets, maybe due to the proprietary cord because apparently there is a cord that works with them. It's not a specific ipad charger and does say it works with Android devices and tablets.
On a side note, what's the best way to determine what your N7 is actually charging at?
Both of my generic chargers won't work either, a 2.1A generic iPad charger, and a 1A standard USB charger. Considering it WILL charge off a 500ma USB port, it's not a current/amperage issue, it's a software/proprietary hardware issue.

I won't say 100% but I would bet the probability is very high. For the 1A charging they all seemed to play the same game with the voltage on the data lines. Not sure you'll get 2A but you'll at least get 1A.

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.

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
cheers.
I have noticed that the power cable that came with the nexus 7 looks like it is separating near the end that plugs in to the tablet. Will any micro usb to usb cable work? If not could somebody recommend one that works well for charging and data transfer for the nexus 7?
Data transfer is easy. Almost any micro/USB cable will work.
Charging is different. The oem cable only comes with the charger for IIRC $25, or you can purchase an ASUS cable (which supposedly works correctly) for about $20
Haven't personally found any other cable that will charge at the same rate as the OEM.
Thanks for the info. I was afraid that was going to be the case. I was going to try my Note II cable on it since the Note II uses a 2A charger also.
Let us know how that works.... Sometimes the 'key' is the charger, sometimes the cable...
my nexus cable broke from a short fall. so i've been using my note 2 cable, it charges well but the only problem is that it's kinda loose so if you're holding you nexus up with the cable plugged in it'll just slide out
