I am using the Nook color wall charger, but left my cable at work. my nook was dead, i plugged in using a standard micro usb and the wall charger, it says wait 15 minutes, which makes me believe it is charging it. Let me go check...still says that. Do you think it will charge? I was able to transfer files with the micro usb cable to my SD card on the nook, but it wont charge it?
It may trickle charge on a non-OEM Nook Color cable (a standard micro-USB), so it would probably require charging overnight at the very least to get a near full charge once again, and certainly longer than 15 mins to get it back to usable from a low charge state.
Depends on the output of the charger, but youd likely be looking at anywhere from 4 to 8 gours for a full charge...

i think i can confirm standard micro usb does not charge this thing, even with the nook wall charger. I had it plugged in from being dead for about an hour and it never came on. Thankfully i found the real charger and am back in business.
It will trickle charge for me with the nook cable hooked up to my computer, but I thought this issue was already covered and others said it would charge with a regular usb cable (again on the computer not via the adapter). Is this not the case? I hate to think I'm reliant on the nook's usb cable and can't charge at a friends.
I have charged my NC with the cable from a cell phone. It takes a LOT longer and in fact, doesn't seem to keep up with even moderate use: wifi and web browsing and battery will slowly continue to go down. Just not AS slowly as being unplugged.
But it does charge.
Hopefully someone will find a way to make the damn thing charge without verifying that it's using a Nook cable.

False, it does charge. I assume at .5A, but it's possible it's lower. Haven't looked.

Plug it into any USB source using any cable providing 500mA, it will charge. It won't SHOW it is charging, as it doesn't appear to show charging unless it's on the fast 1.9Ah speed the Nook charger + special Nook cable provides. However, if it's idle enough the thing does charge.
Sitting on my desk playing with adb one day plugged into my workstation it charged 20% in a little over 2 hours. Of course that's pretty slow, but consider this is a 4.0Ah battery, you cannot compare to your phone charge times unless you multiply by 2.5 to 3!
So 20% over 2 hours would be 50-60% over 2 hours on a typical Android phone battery.
you say it charges, but leaving it plugged in from being dead to the Nook wall charger but to a standard USB did not charge it at all. No power
I have no doubt that the nook cable, plugged into a PC will charge it. It is the cable that is different.
Here are the ways that I have verified that my Nook Color wil charge:
NC wall charger/NC usb cable- best and fastest
NC wall charger/Droid usb cable (standard) - charges slowly
other USB wall charger/either usb cable- charges slowly
computer USB/NC usb cable- charges slowly
computer USB/other usb cable- charges slowly
What I have NOT done is completely drain the battery and test.
My guess is this: it charges slowly without a high rating charger and the special NC cable and when it is dead it takes a LONG time to get enough juice to boot.
Another possibility is that device variance has kicked in and while most people seem to get at least a trickle charge out of any cable/charge source we have, other units simply will not.
that is kind of what i was thinking, the fact that it was dead was not enough to even charge it properly where as if it had kind of been charged then maybe it would be more noticable that it was charging.

It charges no matter what cable or charger as long as it's providing reasonable current. Most USB ports and non-fast chargers provide 500mAh.
If it's dead I don't know, I don't do that to LiIon batteries.

I'm looking for an extra charger for my nc. What I need to know is what is the mah output of the stock changer so I can get one that had the same rating. Our can someone link me to a cheap stock charger.
The output is 5volts / 1.9 Amperes.
Edit, it is written on the charger btw, you could probably have checked that your self .
Where can I get a charger with the same specs? I don't want to spend $20 but if I have to I will just buy another stock one.
I have a 5v 700mah charger that I bought for my phone. Will that work or is the rating to low?
That will work, it just wont charge as fast...

There is this cable from boxwave with a dongle off the end that you are supposed to use to charge from USB chargers. Why would anyone need this?

It is charging, just not as fast and the device doesn't notify you of it. HTC usb wall plug chargers are usually 5volts and 1amp, the nook requires 1.9 amps to charge properly.
/mr
There are no spec listed for that charger so it could be a 700mah or it could be a 1.9a charger.
How many of you guys recommending underpowered chargers actually have any electronics background?
The nook charges when connected to a usb socket on a computer, which provides 500ma as a high power device. So your 1000ma charger is twice as good as using a computer.
In order to get 1900 ma, the nook isn't using stock usb stuff in the charger... but normal usb works just fine because, well, the standard requires it to...
4000 mAh battery should charge fully in 2 hours on the nook charger, 4 hours on the htc charger, or 8 hours on a computer...

Good to note that there's a bug on the NC that makes it appear that it's not charging, when connected via USB connection, but it really does charge.
regular micro usb chargers from cell phones will charge the nook even when it says it's not charging.

The NC will charge from my Droid's power adaptor even though it does not show it to be working. It will take a lot longer to charge with a standard 0.5A USB power adaptor.
In theory, it should take about 4 times as long to charge from standard USB instead of the B&N charger.

It does work. It's just charging slow so you can't necessarily tell. Also. There will be no indicators on the nook to show that it is charging but i'm pretty sure it is. Leave it plugged in overnight and see.

I own one and can confirm it works perfectly.
After scanning through the nookcolor instrction manual, i noticed that the Nookcolor is NOT supposed to charge through the usb plug if connected to a computer...
My does however and once the nook is fully charged, the "nook light" goes green just as it does when plugged into the wall AND moving files is no longer possible.
This is not really a problem as my nook usually has a permanent 67% battery power, but just out of curiosity...
Has anyone else noticed this?
I did not go to 100% so can not say about the moving files, however, changes with USB...did not see if it did before I rooted...as rooting was the 1st thing I did...
Very nice surprise to see USB changing as the non-replaceable battery (Apple kind-of drag) and ONLY B&N charger had me thinking about returning...Now with only the non-replacing battery the only issue and I have a rooted android tab/e-reader I will kept it.
Also I was one of the lucky 25% discount (paid $184 plus tax) THAT WORKED. When I tried the next day to get a 2nd one the store manager said Corp sent a message the 25% was no longer valid.
Ahhh so it happens to other people too...
Anyway, 184 dollars is dirt cheap! i live in australia so i had to get mine of ebay (bn don't ship down here) so it was $290 + $50 for express shipping from US for a grand total of 340 smackeroos! All i can say is thank god for the current US to Au exchange rates.

The Nook will charge from ANY source, it just doesn't show a light on the cable unless it's charging from the included charger. My assumption for this is that it doesn't show charging unless the current is HIGH, and the included charger is rated for 1900mAh. 4 times what a normal USB port provides. Even double what a normal phone charger provides.
So it doesn't show it's charging, but in fact it will. I've left mine plugged into my USB here at the computer messing with adb and such on and off, watching logcat etc and it slowly charges.
Yes but mine does have a light on the cable and once the power reaches 100% the ability to move files is lost and thecable light goes green, just like it does when plugged into the wall...

How long does it take to charge via USB? I feel like when my nook is plugged in with USB that battery life is maintained but a full charge would take a long time. I'm around a computer most of the day so charging via USB is much easier than a wall outlet.
The NC charger provides about 4 times the curent of a standard USB port, so it should take about 4 times as long to charge from USB as compared to the charger.
Okay, so here is the story, I am without the OEM Nook charger (cable) and it seems that no other charger will charge it, I splurged on the Nook in the first place therefore not having the funds to buy another cable. So what I am asking, is, does anyone else know anyway to charge it?
I got a generic retractable microUSB cable. Charges fine from a computer (albeit more slowly than with the Nook charger). Interestingly, it charges super-fast when plugged into a powered USB hub.

It is indeed charging when you have it connected to the computer although the amperage isn't great enough to trigger the Nook into a charging state. Keep it there for an hour or so and you'll notice a difference in the battery level.
I would turn off the auto mount of storage when charging from a computer. I charge my nook using USB every day at the office.

No it doesn't, that's a bug. At least if it's what I've seen.... My NC will sometimes to from say 70% to 100% nearly instantly when plugged into the computer. But it doesn't happen every time.. I haven't tried to figure out what makes it happen, but could be related to repeated plugs of the NC to the computer or something, as I was farking around with disabling/enablng automount when I last noticed it happen.
Later it'll start dropping like crazy and recover the "incorrect" charge status back to normal, like 5% drop in seconds several times in an hour is what I have seen it do in the past.
Okay, so if I leave it plugged into the computer, with auto mounting off, it will charge?

Mine does, I started the day @ 75% a few hours later it was fully charged.
I had same problem, bought nc used and got wrong cable
Used nook wall chager with wrong cable and got " not charging" but i left it overnight, next day it still showed same amount of battery it had night before so i thought it didny charge.
Went to buy nc charher $25!!! Ouch. Plugged it in and battery percentage went from 10% to 99% in 1 second
My theory is that a regular usb does charge it but the nook wont recognize it, but the battery is charged

Well, what you describe is not what I've seen.. What I have seen is that it will charge from ANY source, although it does NOT show it on the status bar or in the Settings, but if you watch the charge percentage (I use Battery Snap) you'll see it charging, assuming there isn't much of a load on the NC. As far as I know, it charges at 500mAh unless it has the NC Cable + Charger plugged in.
What I've also seen is that sometimes the charge jumps to 100% for seemingly no reason when plugged into my PC. Doesn't happen all of the time, but it's not charging fast, and it's not a "recognition" thing, it's completely false. If it jumps from 70% to 100%, it's still only 70% charged. It'll "discharge" really fast later, presumably as the system does whatever it does to determine battery charge (battery voltage etc).
Laptop have smart battery manager to change a/c (when plug in power) and battery when haven't power, so haven't been charged and discharged => not low level . But have nook color smart battery manager ?
Nook color can use 8 hours , if i use more, I will charge it twice a day , I want plug it in power when I am at home
If you use the supplied cable and charger, it will allow fast charging and then automatically stop charging when it is full so you won't damage the battery.
If you use a different charger or cable, it will charge much slower.
Mine won't charge with another cable and plug besides the one it came with. Phone can't charge with NC plug and cable. Is it supposed to to be able to charge with a lower power adapter like the one for my phone?

Apparently you have to shut the Nook down for it to charge with a regular USB cable. That's because a regular cable won't supply enough power to charge the device while it is running.The fact that it will charge at all under these circumstances is an unadvertised feature.

The supplied charger is 1.9 amp. A regular charger is 1 amp. A phone car charger is. 5 amp. That's why if you use the NC charger it's faster.

I want this information in barnesandnoble.com , not fast or slow
the book that comes with the nook states that when the light turns green that it is fully charged and now supplying power to the nook and not the battery (so your battery does not discharge and you can use your nook still), i'm not sure how much more proof you want than this.
As for other chargers, if you get the micro USB Type B (I believe is what it's called), it will charge fast still and SHOULD have auto shut off (since that's built into the nook).
So I left my NC wall charger and cable in my hotel room in South Korea last weekend, and of course I am back home in TX with no way to charge besides normal microUSB, which takes forever.
Is there any source other than B&N for a high-speed (high current) charger and cable? The B&N one is like $25, which is not too bad, but I still would rather find an alternative if possible.
What you're looking for on the charger is something that's rated at 1.9A or better. Most made for the ipad are 2A. The only alternative I've made use of is a Belkin one they sell at Wallyworld for $20 bucks, (same type deal as you but I still had the cable and was still on the road). With the stock cable I get a full charge in about three hours and with a regular cable I get a full charge overnight. If I had to do it over I might have pushed my schedule a little harder and looked for a B&N so I would have ended up with a "spare" cable out of the deal.

Bummer! I travel to S. Korea regularly in Jan/Feb and in early Aug. Team development programs with Samsung at their Cheonan S1 Training Center. Where do you travel to in S. Korea?
Where as finding an adequate charger seems easy enough, its the cable that's the problem. Has to be an official B&N cable for fast charging. A standard microUSB will charge very slowly. I've yet to find an aftermarket equivalent.
Has anyone checked out a touchpad charger? It looks like it's just a standard micro usb charge that puts out 2A. It seemed to charge my nook reasonably fast but I didn't let it get above 95% since I wasn't sure if it would hurt the battery. I'll have to do a better test to see how long it takes to charge

Here are the results of a very quick test that I just performed:
Nook Color running Mirage CM7 latest version (5/18)
Overclocked to 1100Mhz and interactiveX governer
Screen at 100% brightness
Battery Monitor Widget main graph screen displayed entire time
Logging set for every 60 seconds
Test lasted about 5min for each combination
Battery at about 70%
Nook charger & cable
- average reading of +892mA
- mV increased 3844mV to 4053mV
Touchpad cable & charger
- average reading of -335mA
- mV increased 3847mV to 3901mV
Touchpad cable & Nook charger
- average reading of -407mA
- mV increased 3847mV to 3888mV
Nook cable & Touchpad charger
- average reading of +1211mA
- mV increased 3826mV to 4081mV
So it looks like the Nook cable is the key. As long as you have a charger that puts out around 2 amps or so and the Nook cable, the Nook will fast charge. It actually charged faster on the HP charger (2.0A output vs 1.9A for the Nook charger).
I also tried a cheap data cable I had and it stated "USB charging" and the results were similar to using the HP cable but a bit lower on the mA readings.
I plan to run the test again using a high Amp car charger but I think the results will be pretty much the same.
The best combination for a super fast charge is the HP Touchpad wall charger and the Nook cable
Just call B&N, talk nice. They will either give you a new set, or set you up with an order. They gave one to me, 2 day ship too...
My cable broke last weekend. I went to a BN store, and they sell the cable without the charger for $15.

I don't know about the fast charger, but the charger for a samsung cell phone (not a smart phone just a normal phone) phone will charge the nook. I've accidentally plugged it in and it worked. I've not used it for extended periods so can't speak to its long term ability to work.

I've noticed that my NT on B&N firmware 1.4 will charge on a non-B&N charger, but that the charging status shown in settings always says "not charging". My NC on CM7.2 simply indicates it's charging. I don't know if the B&N status really matters or not, but it is finicky about the wall adapter. If/when you re-test, could you please note the battery status?
Meanwhile, I did some testing with a PowerGen 12v adapter. I was able to get the NT showing "charging (AC)" while using the 1A plug on the adapter with the B&N cable. Reading the little booklet that comes with it indicates that "some devices" can pull more than 1A off this plug, including the "HP touchpad, Kindle Fire". While charging, I did get the erratic screen issue while plugged in. With the B&N charger, the same cable didn't cause this behavior on the NT. Not sure what that means, but you basically can't use it while it charges with the adapter. The 2A plug, described as "for the iPad" shows "not charging" (but not discharging). Using a generic microUSB cable also yields "not charging".
I also tested a EZOPower 7800 mAh supplemental battery. I was able to get a NT showing "charging (AC)" while using the "S" plug, described as compatible with the Samsung P1000 (Galaxy Tab) with the B&N cable. The "I" (iPad) plug did not work. The battery itself does charge off any 1A USB source, and will charge external devices at full 2.1A power as it charges. This means you should be able to let this battery power your NC, while the EZOPower battery charges more slowly from a normal 1A USB 12 VDC or AC adapter. Once the NT is fully charged at full rate, the EZOPower battery will itself charge. There were no screen issues with this combination, and I could use the device as it charged (with the usual cautions about the fragile B&N cable, of course.)
I don't know if the distinction between "not charging" and "charging (AC)" actually means anything, but the B&N firmware seems to care, while CM doesn't.
The reason why people notice they need a stock NC cable to 'fast charge' is that While it appears at first glance to be a standard microUSB plug.... it is not. Go ahead, try and plug it into your cell phone (no, it wont hurt your phone). The NC 'microUSB' plug actually has many more pins than the standard 5 (Something up near 20 as I recall). There are the normal 5 upfront, then the rest as further back. When you plug it in to charge, one of the rear pins connects and can supply the 1.9A max charge current. That 1.9A pin is directly connected to the Power Mgmt chip and is the only way to get high current charge.
The <explicitvie delted) whole story
There are three pieces to this puzzle.
1) a high power 2amp / 2000ma USB charger
2) shorting the correct pins in the cable to let the device know it is connected to a high power charger
3) extra long 12 ping next gen micro usb cable.
Some details...
Not all 1.9 / 2amp chargers are actually 2 amps
Some are 2 x 1amp
Some are mis-represented
etc.
I have tried many...
Some are frauds
Some are designed by idiots.
Few actually work
Yes, this is a Ipad spec.
Shorting the data pins (2 to 3) is required.
Go on eBay and look up pwr+ usb filter.
This little USB type a male to female adapter
does just that
shorts the data pins
finally the cable...
There is a new type of micro USB 12 pin connector on the cable.
The other big side is standard 4 pin.
The micro connector is longer than a standard micro USB.
The are some overseas import cables that work.
A standard USB cable WILL NOT WORK.
PS:
using a standard charger and cable will work but takes 4x longer.
Charging while on will run the battery down.
Pretty much stay with genuine OEM parts.
Especially the cable.
Unless you are tech savvy.
Google 12 pin USB
You can source a good 2amp power supply.
You can use OEM Ipad chargers.
HP makes a good 2A charger. PN 157-10157
12V - Scosche big black 4" long job 2 port 2.1a + 1a
However you must short the data pins with the pwr+!
