It only shows up as a USB connection for media instead of charging. Is there anything I have to change on my N6 settings? My old iPhone charged fine.
Maybe it requires a higher ampere charger?

I have never had an Android phone that would charge from car's USB. Never knew whether it was the phone or the car. I can play music from USB thumb drives or some phones through the car's USB port. Always have to use the 12v charger. If your i Phone did, you might see if a "Charge Only " cable would work. That cable is a good thing to have, regardless.

Can you send a link ? I wouldn't mind buying one.
All android phones determine whether a charger is a wall charger or a computer by whether or not the two center USB pins are shorted. If they are, then it's a wall charger, and will show "Charging (AC)" in the battery screen. Wall chargers designed for iOS devices work differently, and as such most of them will only charge Android devices at 500mA, which is the the same as a computer's USB ports, regardless of the marked amperage. In other words, a 2A charger designed for iOS will still charge Android devices at 500mA.
"Charge Only" cables are also an issue. Many of them don't actually have center pins at all. Android considers this an "open." In a "short," the resistance is zero Ohms. In an "open," the resistance is infinity Ohms. (Infinity, being the exact opposite of zero.) So, a lot of charge only cables will cause your android device to charge at 500mA.
The solution is to ensure that your charger is designed for Android. Or, buy a charge only cable designed for android. Or, buy an adapter that turns any cable into a charge only cable designed for android.
Yes, I know that's all really confusing. Here's the real deal. Find a charger and cable that works for sure (oh, I don't know... like, the one that came with the device!). Plug it in, and go to the battery screen. Ensure it says "Charging (AC)". Once that's a given, replace the cable with any other cable that you want to use. If it still says "Charging (AC)," then it's a good charging cable. If it says "Charging (USB)," then it's not a good charging cable. If you ever plug a known good charging cable into a charger, and get the dreaded "Charging (USB)," then you know your charger isn't Android compatible, making it a bad charger.
So, the TL;DR of it all: Use the original charger to test cables. Use the cables that pass that test to test chargers. Other than that, it's a crapshoot.

Most "built in" car USB ports are 500mA, so will show as USB chargers (not AC chargers). Those that are higher (1A or 2A), tend to be designed for iOS devices (so will STILL show as USB chargers, unless you get a cable or adapter that has the two center pins shorted). I've yet to see a built-in car USB slot that will charge an Android device in AC mode.

That's a very hard question to answer. Chargers tend to advertise iOS compatibility, but do NOT tend to advertise Android compatibility. However, they often do advertise a specific android device. So, for example, you might find a car charger that advertises compatibility with the Samsung S5. As long as it's advertising compatibility with any Android device, it should work with YOUR Android device. Just be aware that most manufacturers don't understand the whole AC vs USB thing, so even if they advertise compatibility, it's not ensured. Just be sure to buy chargers where you can take them back for a refund if they end up not showing up as working in AC mode for your device.

Another hard question. There are two types of "charge only" cables. One that has the middle two (data) pins shorted together, and one where they're just missing (even though the pins themselves may be there... they're not connected). The former would work fine. The latter wouldn't (or more specifically, it would work, but only show up as "Charging (USB)" in the battery monitor).
Determining which is which before purchase is virtually impossible. The only way to really tell is to try it with a known good (1A or higher) charger.

Nope. They're designed to use that type of charger. Technically, rapid charging may decrease battery life, but you'll probably long since have moved on to a new phone by the time you'd have to worry about that. The only caveat is that you should NEVER start your car while the phone is plugged in (on ANY car charger). When you're starting your car, the 12V electrical system in your car can experience quite a large power surge, and that can transmit through the adapter and hurt your phone. The electrical system in your car is built to withstand that. Your phone isn't. Most (quality) car chargers will have a similar warning somewhere, since it's a pretty standard warning.

Personally would you go with the charger you listed above? Amazon also lists USB cables that my N6 came with which is model skn5004a. Should I stick with that type of USB cables for extra cables I carry while traveling, work and auto?

Just reading up on USB chargers, and I found somewhere in a thread here about phones defaulting to smaller ma when charging via USB if the connector didn't have the data pins shorted or something.
So, I was wondering a couple of things:
1) If the default charger supplies 700ma, do you think that is the most the Nexus S can draw? Does anyone have one of these shorted USB chargers? Does it charge the NS faster?
2) If it does charge faster, how hard would it be to do something similar to shorting the data connections? I have a generic AC-USB cable which I currently use for my iPod touch.
3) Is there a way to check if it is already shorted out? The USB charging port looks similar to ones on my computer, but I'm not sure what to look for.
Thanks for any help! Maybe if we can sort out this stuff, we can provide a solution for those looking for faster charging!

Nah it's not the wrong thread that was one of my questions! I'm not sure exactly where you would do it, but maybe if you skinned the wire, then cut the data lines it would work?
Not sure which end you would do it on however, but that may not matter. Any other ideas?
The two center pins in the USB carry the data. If you pull them out, the cable won't be able to connect to the computer.
Sent from my Nexus S
Wow - you don't need to do this and you wouldn't want to in a computer anyway.
The USB specification says that 500ma (@ 5v) of current should be available from a computer's USB port. Of course, the actual wires can carry much more than this, so manufacturers can tell their phones to takes as much current as is offered.
Almost all computers limit their USB power output accordingly - this is why some opld usb-powered external hard drives needed 2 USB plugs to get enough power. The only computers that I am SURE emit significantly more than 500ma on their USB ports are first and second generation MacBook Airs.
Some phones, the N1 and every other HTC specifically, look for a specially shorted cable to "know if they are plugged into the wall adaptor" as opposed to a computer USB port. In reality, this is just a way to make you specifically buy HTC chargers as opposed to third-party off-brands, because plugging one of these phones into an off brand charger will limit the current draw to about 450ma.
If you want to know if your Android phone thinks that it is in "USB" mode or in "AC" mode, just plug the phone in, open the dialer, enter *#*#4636#*#* and then select battery info. If your phone is one that cares (not all do), it will say USB if it thinks it should be in USB charging mode, or AC if it thinks it should be in AC charging mode.
I would not try shorting out the middle pins in a cable and then plugging it into the computer. First, most will probably just disable the USB port completely, shutting off even power you could draw. Second, if it doesn't shut down, you run the risk that a badly-built USB port might not properly limit the current to 500ma - and since they are not designed to furnish more current than that, you might melt something expensive or start a fire. third, if you make a mistake, you risk shorting out either your phone or your computer, which might ruin your day, week or month, depending on your financial means to replace the system that cooks itself.
I would just run out to your local store, pay 15 bucks for a 2A third-party usb charger brick, and go to town. That will work perfectly - this is what I use, and it probably cuts the charge time by 30-40%. Obviously, this indicates that the NS is not capable of drawing a full 2A - I have not put a meter on it, but I would bet that it limits itself to somewhere just under an amp in.
I have recently bought both a 2A wall charger and car charger and my phone does not recognise either of these as anything more than a 500mA source.
Is it really just a case of opening the car charger up and shorting out pins 2 & 3? they are currently not connected to anything in the charger.
If it's indeed a matter of shorting the data lines, then I think you can skin the wire as suggested by others, but then cut the data lines, short the end that leads to the phone, leave the end to the computer open. I think it's the phone that tries to determine whether the data lines are shorted.
Edit: Can someone measure the continuity between the data pins with the stock charger? I wonder if they are shorted. I'm still waiting for my Nexus S to arrive, so can't test it.
Yup, the data lines in the stock Nexus S charger ARE shorted.
I just modified a cheap 1A car charger by popping it open, soldering the 2 data lines together and putting it back.
The report on the Nexus S before I did this (*#*#4636#*#*) said "USB", and afterwards it now says "AC".
I will report back after I make a road trip if this improves the GPS + Pandora + Screen in car situation. I suspect it will.
----------------
Yup, the car charger seemed to actually maintain and increase the battery this time. Seems good.
The NS supports chargers output to a max of 1000mA, as it says on the back of it, where the battery resides.
Hi guys, I accidentally left my charger and USB cable at a friend's house 700 miles away during a visit. She sent it back to me, but it's been a bit over two weeks and I'm tired of being Nookless, especially with all of the new stuff developing (cyanogen on the way? AWWW YEAH!!).
Neither of the two BN stores near my house have replacement charger/cables in stock and it appears that the BN website does not either (not even a price listed, just a pic/description).
What is the cheapest way for me to get some power in this thing? I wouldn't mind charging solely through USB. Is the stock NookColor USB cable any different than a normal micro-usb cable? Can I just order a normal $2 cable from amazon and expect it to charge?
The cable that comes with the NookColor differs from a standard micro usb in a couple of important ways: It has extra pins to deliver a higher charge. OK, I guess by "a couple" I meant "one that I am aware of." Alright, maybe one more: The charger itself is rated at .5A, which is higher than the standard plug for usb chargers.
You might be able to trickle charge from a standard usb. I was able to get some power, but not much.
Here's one more thing to do:
Ask the manager at B&N if she has any extra chargers and cables in the back. Here's why I say this: I had to return my cable yesterday because it wasn't making proper contact with the pins and thus was not properly charging. The manager told me that he has a heap of NookColor plugs and cables in a box because when they send units back to wherever they send them for repair or reconditioning, they are instructed to send only the Nook, and not the cables.
It's worth a try.
Good luck.
It does charge very slowly when connected to the PC...It will charge overnight if not in use..
I have some Nokia cables (from my mobile) with Micro-USB, they are loading the Nook nearly as fast as the original one. Very handy for charging in the car.
I have been charging my nook with only a standard cable since day one. My nook came with a bad cable and at the time was one of the last nooks in my area. I have been calling B&N almost weekly for over a month and they keep saying they will send me a cable but I have not received it yet. I have had no problems charging my Nook overnight. I even emptied the battery once and it still charged fully over night.
A regular microUSB cable will eventually charge the NC, if it's sleeping. No 3-hour quick-charging, though.
Does the slow charging really have to do with the cable?
On high draw devices (e.g. iPhone or Palm Pre) the charger shorts the data pins to signal the capacity for higher current draw. The cable has nothing to do with it.
I have noticed the Nook plug is longer than a standard micro USB plug, but that only means you can't use the Nook cable on another device's micro USB port.
Anybody know the potential problems trying to root with a non-standard Cable?

Is this confirmed to be true? If so, what allows a non-Nook USB cable to be used with the Nook?
I'm sure the cable itself is different, either by using the data lines as additional power lines for higher current capacity, or perhaps by adding some resistors to pull the data lines to certain voltages so that the Nook can identify when the "right" cable is connected, so that fast-charging can be enabled. I just can't quite grasp the idea that the cable is not physically compatible with other micro-USB devices.
I am able to use the original nook usb cable, my samsung moment usb cable, and others for data purposes, no issues

Actually... .5A is the minimum for all plain jane USB ports.
If I remember right, when I flipped the charger over when I first got the NC, it is rated at 1.9A, which would make sense considering the size of the battery we are charging and at the speed we are charging it at. Hell, my Epic uses a 1A charger and it is only 1500mAh battery vs the NC's 4000 mAh.

Here is a link for a Hi - Power USB Car Charger. It's 2100mA and can run and charge an Android Tablet or iPad at the same time. Also the microUSB cable they offer, shows "Charging ( AC) ” When plugged into my Captivate. Most just showed "Charging ( USB) ".

.5A is nothing. Most phone chargers now are rated at 1A with ones for tablets going above 2 as someone else mentioned. Most BT headset chargers are rated at .2-.5A in comparison. Some GPS units have charges rated over 1.5A. My Dash unit had a 2A.
And if I'm not mistaken, if you're connected to a computer you will only get a tricklish charge as it's limited to .2 or .25A (I believe).
In regards to actual cables, any microUSB cable will work. I've used stock ones from Samsung and Palm phones as well as cheap 50 cent ones from Meritline. And if the Nook one is actually longer? Why wouldn' it work in something else? The cable will just stick out further.

I'm just curious. I'm not sure it's safe, since one has a 10W output, and one has a 5W. If you do, have you had any problems? Notice it charging faster than usual?
deleted +10
Yeah, that's what my phone charger outputs. The iPad/iPhone chargers have the same output as the Nook/Android phone, and they claim to be safe to use with either one. Not sure if that applies to android phones though, or if there needs to be some safety circuit in either the phone or the charger. Would love to only have to deal with one charger...
It's 5 volts at UPTO 2 Amps. If your device can only draw 5W thats all it will do then overcharge protecton etc cuts in.
I've used the Nook charger on
Nook Color
Nexus One
Blackberry
Plantronics SteroeBluetooth headset
No problems.
As long as the voltage is correct you are good to go. The phone draws amps from it, it won't draw more amperage than it needs.
I noticed that my nook USB cord doesn't fit my Motorola Droid 1, however, my Motorola Droid 1 Phone charger fits my nook :\
Anyone else confirm this?
Also, when plugging in the nook I get no indication that it is actually charging, is this suppose to happen?
EDIT: It appears that it doesn't charge when I plug it into my computer, if it is, it is super slow and doesn't display that it is charging. However, when I plug it into the wall with an A/C USB adapter it shows the charging icon.
from what I got, The nook charger has 6 more pins making it faster, but not compatible with other devices, but the nook itself can get a normal charger and it will be fine just slower.

Except the 6 pins (or w/e num) are added on top of the existing ones, so unlike say a headphone jack with an extra layer for using a microphone, its not backwards compatible (atleast not without an adapter) for normal ones (like my headphones example), rather troublesome imo.
But the power converter works fine for phones.

Thanks makes sense.
Just tried it and it works fine on my phone too. Has to use a generic micro usb cable though. The nook one did not work.
I wonder if the reason the nook color cable doesn't work with other devices is due to the charging light built into the cable. I'll try charging it from a non-nook cable to see. If it charges fine either way, I'll be able to cut it down to 1 charger 1 cable. Would be far more convenient.
Has anyone else noticed a slower charge on non-nook cables? If it really does have more pins, that would be a dissapointment. The cable is so short, I'd probably have replaced it anyway.
the nook color charger connector is shaped slightly different -- its longer --, so it wont fit properly into other devices that use standard microusb.
Is there supposed to be some kind of notification when the unit is off, that it is charging properly. I bought my nook color used and it didn't come with its official charger. I have a bunch of standard (low amperage) USB chargers and 1 iPad type (2amp) charger. I tried the iPad one and the unit gave a "Not charging" message in the settings screen.
How long does it take to charge when using a 3rd party charger?

How long does a non-BN charger AND Cable take? Four times longer. It's .5A vs 1.9A. You can get by with a 2A charger, but you must have the B&N cable to charge at the 1.9A rate.
So this is my first motorola and I had heard of the issues they have with non motorola chargers. Now I am experiencing it first hand. With the same ac charger I have charged many phones with and is capable of 1 amp output (D4 charger is only rated at 850 mA) my D4 struggles. With the device off it charged painfully slowly. While on it cannot even charge. It discharges while plugged in despite the charging indicator and reporting "charging (AC)" in status.
How does it know it is not a moto charger? Is it just about the resistance between the data pins? For most other phones shorting the data pins on the charger indicates to the phone that it is a high current charger and not a computer USB port. Is there a similar trick for motorola phones? I would rather not have to purchase an overpriced moto oem car charger. I have a perfectly fine 1.2 amp car charger soldered directly into my car's 12v system behind the dash. Can I make it work?
Thanks!
On a regular basis I successfully charge my D4 using both a charger from a Samsung Reality feature phone and from a B&N Nook Simple Touch, in addition to the one that came with it. I've also used a variety of car chargers.

Actually, so far I have only one charger that had any trouble charging the phone (it was a $3 charger with 2 USB ports), but the $3 charger with ONE USB port works fine, as does the Nook Color charger, Blackberry charger, and Samsung charger I have tried it with, as well as both my old car charger and Lenovo's always-on charging port on their laptops.

Not sure how it knows one way or the other. I've successfully used a few LG chargers to charge my D4. The only really hickup I've ran into is the usb cables from those lg chargers won't sync data to the phones when plugged into a computer, they'll still charge off the usb port but won't read as a usb connection to the computer.
Heh, captcha is trynply.
Every charger I've used, including an old charger for an EN-V, kindle, supplied, and various other phone chargers works just fine with this phone. Probably have a bad charger, guy.
Thanks for the replies. I guess I was wrong. My modded car charger works just fine. I guess its just time to retire the old charger that I have been using. I think it might be my old nexus one charger.
A more important question would be does the thing charge over computer-bound USB ports?
When you're without a charger, but there's a USB cable that fits your phone, sometimes a regular USB data port is the only that is around... even though it might take a really long time.
Try a computer bound USB port, then try your actual charger, again. Or do the hard reset (vol down plus power, hold until it actually does it), which is just like pulling the battery.
See how that goes.

It does in fact charge via USB port. In fact, it has a 'charge only' mode. Depending on how much juice your port puts out, and what you are doing with the phone, it will charge slowly/not at all, though.
from my experiences, the droid 4 will not accept lg microusb cables, the charging bricks work tho. i use a blackberry microusb on mine along with a Logitech and the stock moto ones. 1.2 amps is a bit high but not crazy sounding. personally, I charge at 1 amp.
Sorry if this has been asked before as I wasn't able to find a topic. I've noticed my phone only charges with certain chargers of mine. My car charger refuses to work along with one that I keep at work. The only thing I can think of is that the phone requires a certain amperage to even recognize that it is plugged in. Is this true?
Have you tried different micro usb cables? I think that is more likely to be the problem then the power supply itself.

No, but I have used the same cables in a different adapter and it work.
Different chargers have different wiring on the data pins (2&3) depending on the host device. My experience with Android devices is that most (not necessarily all) expect data pins on AC chargers to be shorted, while Apple devices expect to see a load across these pins. A number of Android devices I have had drop their charging rates when that load is encountered just as if it was plugged into a computer's USB port (but can't say for sure whether they all do).

I think that the point is in voltage rather than in current. A lot of cheap adapters charge with the voltage above 5.2 what is approximately the margin where the electronic protection in phone blocks the charger to prevent it from damage. Low current could never be the problem besides the charging circle is prolonged.
