    Nook Color charger uses special micro-USB connector

      There are lots of discussions concerning the special charging micro-USB connector and cable for the Nook Color.

       

      Here's the deal - the normal USB port or charger produces 5v @ 500ma.  The Nook Color AC adapter can produce 5v @ 1.9A (1900ma).  Actually, any charger will work ok, it just takes longer to charge the battery...  the more "amps" the faster the charging rate; bigger bucket filling the bathtub.

       

      To handle the extra current flowing to the Nook Color,  the special micro-USB connector is "longer" and has an extra 12 pins at the tip,  that go deeper into the special micro-USB connector on the Nook Color.

       

      A normal micro-USB cable can still be used for data transfers or slow/trickle charging,  since it will only go in the normal depth and not make contact with the deeper special pins.

       

      Here's a photo of the special extra long micro-USB connector....

      Notice the extra 12 pins at the tip - vs just the normal 5 pins...

      That is why this cable will NOT work charging other micro-USB devices,

      but the charger works just great when used with other normal USB charging cables.

       

      So - when on vacation or travelling - I just bring the heavy duty Nook Color AC adapter, the special micro-USB cable, a normal/standard micro-USB cable,  a mini-USB cable, and finally an ipod/ipad USB cable..... one heavy duty AC adapter for USB & all the different cables.

          So, I have to have this special cord to charge properly? Why then when I use the cord that CAME with the Nook, does it not charge properly....as fast as stated?  I've only had my Nook color for about 2 months and already the cord appears to be worn out! Come on! Surely these things are more durable than that!

              The plastic part of the usb connector, where the glowing "n" is, actually broke on mine.  Not sure how it happened, but just broke off.  I have scotch tape around it now.  Not so pretty, nor durable.  LOL  I should call to get it replaced come to think of it.

                  Mine broke too! I've had THIS nook about two months...I mean really??!! My last nook lasted waaaaaay longer. Wish I hadn't traded it in for a "better" version.

                      Take it back, if you've only had it two months, they'll give you a new one.

                       

                      ive had my Nook Color over a year now, and I'm still using the original cable with no problems.

                        Its the primary failure point in the design, which is why they don't use the same design in their newest Nook HD's.

                         

                        Take it back and get a new one ~ they won't be surprised to have to swap out a broken plug.

                            Do I understnad you that a regular USB charger will work with the Nook color? I have had mine for one year. Got it last Christmas. The pins end has always been touchy but it worked and I was careful with it. The last charge I had to giggle the wire until it said it was charging. Now it won't charge at all. I have not been o BN yet. It was a gift. I bought a charger bundle that included a nice cover for the Nook for less than a nook charger would be if I had to buy one. The charger end is half the size of the Nook charger end and the Nook does not seem to recognize it. I believe you said it would charge slower -  but he Nook should say it was charging, right?

                            I guess I need to go to BN to check whether it is the cord or the device.

                                From what I understand, it will charge slower and it will not say "charging", but it is. Check the battery level, plug it in and come back in an hour or so and see if the charge has increased.

                                  Yes, but only slowly. Keep in mind, there are different sizes of AC-DC adapters. I find that on a 500 mAH adapter (1/4 as big as the NC charger), using a standard micro-USB cable, mine will charge up over 8 hours or so if I remember to turn the screen off. With the screen on, it can barely quicker than it discharges.

                                   

                                  It's slow, but sufficient for overnight charging.

                                    The HD/HD+ has a different connector because it has to support (not yet available) an HDMI interface to digital TVs.
                                    Not just V+, gnd, data-in, data-out -- but stereo audio (if not more), along with whatever HDMI uses for video (RGB or the other component color signal).

                                  I have had the same thing with my cord since the secoond month I  had it.  the plastic Part with the glowing N has been taped for almost two years now.  It just now started getting loose and wiggly while plugged in.  I thought about retapping it but considered buying a new one.  seeing the reviews 1.5 stars on the B&N sight makes me wonder if they should revamp the plug some how.  I need a new cord but do not want to spend the money for one that may brake again in just a couple of months.  I love my nook color and do not want replace it but if there are other readers out there that can be charged with any universal cord like the Kindle than I may just go that route.  If I have to keep replacing the cord I would think in the long long run it would be more cost effective.

                                  @cokids:  Sadly no, the cables aren't better-made than that.  Fitting that many pins into the opening makes it more likely that some will fail, and the number of failed cables, chargers, etc. up until now is impressive.

                                   

                                  You can pick up a replacement cable that will charge your NC, slowly, from most places that carry cell phones. 

                                   

                                  I found that the one I picked up also failed pretty quickly - I think these cables, both the standard USB ones and the NC charging ones, are cheaply made commodity items.  My thought had been to have one for charging and one for communicating to my computers. 

                                   

                                  If you bought your NC at BN, they're pretty good about replacing them.  Best Buy is good about it as well, at least one report indicates - but it's useful to go to the place you actually made your purchase if you bought it in a physical store.

                                    Hi I know this topic is old but i've had problems with my NC charger for some time now and had to purchase at least three so far, finally today I called the store mngr myself and complained, she was very polite and  understanding as she have experienced the same problem and stated they were aware of the issues where the NC chargers were concerned, at the closing of our phone conversation she told me to come in and pick up a replacement at no cost..

                                      • Re: Nook Color charger uses special micro-USB connector

                                        I'm not sure what or why you bought a new charger - when it is pretty well known here that as you found out, if you take your charger & cable back to the BN store, they will "probably" give you a replacement.

                                         

                                        I replaced mine once - when the connector end had trouble with the color leds - but charged fine.

                                        It now shows "red" when un-connected, but the "yellow" and "green" appear ok when charging.

                                        SO - for me - it works... even if not quite right -

                                          As stated in more than a few threads,  because of the factors mentioned above, it is absolutely essential that you gently plug the connector into your NC..  Forcing it can damage and mis-align these pins causing failure or intense heat, etc.  It is a flimsy connector.   I can't tell you how many times that it won't easily slip in, and I have to back off and carefully watch what I'm doing until it connects and seats easily.

                                           

                                          In addition, reading or using your NC while charging can cause problems.  The flimsy connector just isn't built for that kind of stress.  In reading about laptops, the number one failure is the power cord or connector on the laptop.  Next is the usb connectors, people forget about being plugged in and these connectors get tweaked due to cords at sharp angles, and banging when connect to power or usb.  The same is now obviously true of the NC.

                                            I suggest you dig a bit deeper.   While a lot of what you say has been posted before and technically is "true" (longer connector, extra pins, etc.), a standard microUSB plug has FIVE pins and the shell for 6 "wires"....but the :A: end of the cable only has 4 connectors.    Power +, Power -, Data + and Data -

                                             

                                            If you'll notice in your attached picture, there are only SIX wires going to the connector, so even if there are 12 "traces" on the connector, they only attach to 6 "wiper" pins.    Wiper pins are the bent metal "springs" that push against the fixed connector to create a connection.

                                             

                                            Unlike network or phone plugs and sockets....where the wiper pins are in the socket and the flat traces are in the plug....in USB, the wiper pins are in the plug, and the fixed traces are in the socket.

                                             

                                            And I would presume, but do NOT know, that the extra traces shown in your picture are simply there for redundancy and current carrying capability.

                                                Hi,

                                                 

                                                I am facing problem with charging my nook tablet and noticed that it is due to the USB cable(as it is charging when I use another USB cable from nook tablet).

                                                 

                                                As per your information, nook tablet should charge at a less pace even when we use normal generic USB cable but in my case I have tried using many USB cables with the charging AC adapter came with my nook tablet but no luck. I keep seeing the message discharging :smileysad:

                                                 

                                                Any suggestion on how to use any other USB cable to charge tablet using standard AC adapter received with nook?

                                                  I turn off the Nook, plug in the charger and the Nook turns on again so it's running while charging and won't fully charge. It used to stay off when powered off.  If I power it off before or after I plug in the charger, it still turns on
