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
I have two other devices that also use M-USB for data transfer, and they work just fine.
I picked up a few of these a while back and they work as well:

It seems that you can call B&N support for a new one if you had issues with your original. Not the OP's problem, but Some have had the issue.

So the idea is that these could be used only for data and trickle-charging? Even if it's connecting the Nook to its official power-thingy (is there a name for those?)

I am just using it for data transfer and charging with the stock wall unit. As far s using these cables or other USB devices that using the MicroUSB interface would require some type of software driver (USB Host) in order to make that work. As far as I know at least.

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.

Wow thanks for that link. From the day I got my Nook I couldn't use the included USB cable to move data, but it would charge like a charm. Now I'm getting a replacement.

True but.... I have been calling for well over a month and first they could not ship me one because I bought it at Best Buy and they did not have the warranty info yet from Best Buy. I finally got past that and since the week after Christmas they have been shipping me one each time I call. I have yet to receive one. I am going on 2 months now trying to get the cable shipped to me.

I don't think there are any.. I do all my ADB work using a "non-standard cable". The usb cable that came with my nook wont let ADB work right. When I type ADB devices with my factory cable I get the serial number but instead of device it shows suspended or something like that.

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) ".
Sent from my Samsung Captivate with Perception 10.3, Firebird2 v0.8 #77 Kernel, Firmware 2.2.1, Modem T959TLJL3 using XDA App
.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 tried posting a day or two ago about this, but wasn't able to get any replies or any help at all actually : /
Anyways, for some reason ever since I rooted my nook, when i plug a charging cable into it, it either
(a) Pulls out of sleep mode and shows the Lock Screen, which drains the batt
or
(b) Will actually turn the device ON and do the above stuff, making it really hard to charge in general
Is there any way to fix this? Right now my nook keeps hovering below the charging line and reboot looping, then when it does have enough power to actually full boot, it drains itself faster than it can charge bc it runs the screen at full brightness.
HELP PLZ!?
Your charger must be bad or some other such problem, because that's what the Nook does: plug it into the charger and it boots itself up or comes out of sleep to the lock screen. It will blank the screen relatively soon after if it is running correctly.
On top of that, the charger supplies way more than enough juice to charge even under heavy use.
Are you using the nook charger and the nook cable?
Im using a MicroSD cable either through the computer or through an actual AC port in an adapter.
Im basically now at the point where I can't charge the thing enough to get it past the "Battery is Dead, wait 15 mins" mark. It sucks so hard :<
Im thinking I may have to take it back to Best Buy and try again, I have the warranty on it, just I really dont want to do that! >_>;
I am having the same problem......

Are you using the official B&N USB cable and charger that came with it or just generic ones?
Using a standard MicroSD Blackberry adapter.
I tried going to bestBuys (i work for them) and getting a black NC cable, no one sells any!
My next stop is going to be BN themself. Is it really that big of a difference what cable you use?

Yes, it does make a difference. A standard USB cable and charger takes 8 hours or so to charge an NC. The B&N cable and charger that came with your NC can do it in 2. Use them.
yes, it seems to make a difference. I can only connect to the PC [mounting the drive] with the originally cable. With the generic cable, it will charge but doesn't seem to charge as fast [less than half the speed]. I would suggest you try to get your hand on a original and see if there is a difference for you also.
from the user manual:
CAUTION: Only use the Barnes & Noble power adapter and custom microUSB cable supplied with your NOOKcolor. Other power adapters might damage your NOOKcolor and its battery. Do not use a power adapter and cable intended for other models of NOOK eReader. Use only a NOOKcolor power adapter and cable.
NOTE: Using your NOOKcolor’s microUSB cable, you can connect your NOOKcolor to your personal computer to transfer files. Connecting over USB cable does not charge your NOOKcolor, however. To charge your NOOKcolor, you must plug it into a wall outlet
Hi,
after having problems with running out of battery:
http://forum.xda-developers.com/showthread.php?p=19807551#post19807551
I can now hardly get any energy in the Nook. I used the original power cord and when i plug the cable in, the Nook Color recognizes this and poweres up. The display shows a Battery sign (i booted in the stock ROM) but it dont seems to be normal. Sometimes the LED of the cord flickers green and sometimes it stays orange. Sometimes the Battery symbol goes away and pops up in a second - it seems as is there a defective contact. At the moment i have plugged in the cord and the LED stays orange. But the display says: Not charching. When i power off the Nook it stays off with the cord plugged in (which is also not normal - normally it boots again).
I tried also two other USB cords but the display says: not charging.
Sometimes (i think when it flickers) it bumps some energy into the battery which is 51% at the moment.
Do you have any hint or trick for me?
You may have a bad cord. You can power down the Nook after it is plugged in and it should stay powered off. If it restarts you have a short somewhere. Does the cable fit snugly in the port? You can't use another cord. If still under warranty ask B&N for a new cord. If not, they are $14.95 from B&N.
I've bought it in the US and iam living in germany. Can't exchange the cord on warranty

You cannot use another cord unless you want to completely shut down the Nook and wait over 24 hours for it to charge. The Nook cable has a 2 step pin configuration and you will not get the needed power to charge it properly. B&N ships internationally.
Pat... the only way the nook stays powered down with charger connected is if you select power off from the power menu... if you jus hold the power button it will reboot...
You can use a standard uUSB cable without taking so long to recharge if you shut the screen off after the charger is connected.

I know that Den. That is how I always charge mine. From what I have read from other users using a different cable, even when completely powered down it takes forever to fully charge. Someone else suggested using a higher capacity charger but I think that is just asking for trouble trying to force more current through less pins.
Regular micro usb cable plugged into AC will yield 1000mah charge rate, more than enough for the Nook to charge even with the screen on. I plug mine into my laptop for overnight charges (USB power yields 500mah charge rate) and the screen has to be off for it to charge. ~12 hours for it charge from <5% to full this way. Half that if you're plugged into a wall (also with the screen off).
The proprietary cable has an additional pin that lets it charge at a rate of 1900mah.
So yes, a regular micro usb cable works fine. In fact I only use the B&N cable if I'm in a hurry (due to their tendacy to break).

Weird, cause I charge it every day without it being shut down. Even with the screen on (but with the backlight off) it still charges. If the battery is dead I plug it in and one hour later the device turns on with 10% power. I then have to turn off the screen because it will stay at 10 forever until I do that which is weird cause the rest of the time I have it in that state it will charge. So yeah another USB cable is workable

I stand corrected..........
Hi,
i tend to say its a hardware problem. The LED of the Nook cord flickers sometimes. As i said before, Nook color tells me, it wont charge although the cord is plugged in.
The best i can do is remove my SD card where CM7 resides and boot into stock and charge from there. Although the LED flickers it charges - slowly, but it charges.
When i use another charger (with another cord) it wont charge at all. Furthermore i lost overnight again 80% of battery (booted in CM). I dont know why.
Just a further remark: Although i used the Nook cord i have connected it to a HTC Desire charger since the Nook charger dont matches to german electric network. Nevertheless i used this configuration several months and had no problems at all.
One stated that BN ships international. May i also send my Nook back to BN and do i have warranty? My Nook was bought in may.

That might be more problematic. The Nook Color is not available outside of the US. If you have a US address and credit card attached to your B&N account you may be able to have a purchased cable shipped. Trying to get a warranty claim shipped outside of the US may not be in the cards.
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+!

Not long had this tablet but I have tried 3 ifferent power banks to charge this with no success.
I know there are problems as the Samsung has detection built in which wont allow a lot of other brands to charge it.
I have 3 standard mains Samsung chargers from another tablet and phone plus the original that came with this. Original rated 5v 2amp, other 2 rated 5.3v 2amp. All work fine.
I have an anker 13000mh power bank (2amp output) that charges my s5 phone at 1200mh at super fast speed, it also powered my old tab s 10.5 fast. It will not power this model at all due to the tab detecting it.
Also have 2 beefy jbl charge speakers which can charge anything at 2amps but not this tab at all.
Has anybody found a power bank that works with the T813 ?
Don't care if it has to be Samsung made I just need one that works.
Workaround
Well I sort of have a fix.
I tried about 10 USB cables I had lying around, from other devices such as Xbox one, phones, tablets, speakers, power bank etc.
None of these worked in my anker power bank apart from one.
This is a cable about 6 inch long and it came supplied with a free phone 1a power charger from EE / Orange.
So not ideal but at least I can use the power bank with this device albeit a very short cable.
I have tried to find another cable like this but with no luck, so when this one breaks I'm probably screwed using a power bank unless I pay well over the odds for a Samsung made one if I can find one.
I did try and butcher an old USB cable and tried variations of shorting the data pins, with and without a 10ohm resister but no luck there.
If anyone knows what the difference in these cables is or could give me a pointer as to where I may get one (as long as I know what I'm looking for) it would be greatly appreciated.
As it stands the tests I did on the standard charger and original Samsung cable using an amp meter app I was getting between 1000 and 1500 mA
I was getting pretty similar input from a fully charged anker 5v 2A power bank using this certain USB cable.
