    Nook Color Charger issues

      I determined that the charger gets hotter the lower the batt. At 20. - 30% it gets almost to hot to touch. Starting Above 50% it is warm. Even starting at 20% it will cool when it gets above 70 to 80%.

       

      mbratch posted a great explanation ;  "The charging current in a charger is higher when the battery level is lower. And the charging current abates as the battery charges. Or stated another way, the battery charges slower and slower as it approaches full charge"

       

       

      Mine does not heat up enough to leave skin. It isn't even uncommon for chargers to be hot when working hard. It does get hot enough to be quite uncomfortable to hold on to. I would not be very concerned had I not read several posts (here and other forums) about the melting and the adverse affects on the NC when plugged in. My NC functions the same weather plugged in or not so I figure I have a working charger.

       

      I AM curious to see what other people find.

       

       The ones that melt are most likely defective and need replaced.Do not take any chances.

       

      It would be helpful if we had more data.

       

      Please post results.

          I always understood that it is best to let the battery discharge as much as possible in order to prolong battery life. Is this true?

              I've heard that as well. As a rule of thumb, I usually let my Nooks (Classic and Color) display their "time to recharge" screens before I get out the chargers. I figure those screens were designed into both systems for a reason, and I follow them to the letter to be on the safe side.

                From what Ive heard it is best to NOT let charge go lower than 25% +/-  and only charge to 90% +/- . I have followed this method and it seems to work. I know quite a few people that dont and they are always complaining that the run time on thier device( phone, ipod etc) is not as good as when it was new. This is just an oppinion.. Results May Vary. :smileyhappy: 

                 

                 

                ** The 90% is less important then letting drop below 25% IMO**

                • Re: Nook Color Charger issues

                  The idea of always discharging a battery almost completely before recharging is obsolete information dating back to NiCd batteries. The phenomenon of losing capacity by recharging a partially charged battery is called "memory". The newer NiMH and, especially, Lithium batteries have almost no memory effect, so you should feel free to recharge your battery at any point. In fact, the battery can be damaged by real deep discharge cycles. Devices, like the NC, will force a shutdown long before that deep discharge point is reached.

                   

                  Two slight caveats:

                  1) You might want to occasionally let the battery discharge down to where the NC shuts off. This is primarily for calibrating the NC's notion of what a full battery cycle looks like. Sometimes the reported percentage full can get out of whack with the battery as it ages, and this allows the NC to relearn what the discharge curve really is.

                   

                  2) If you store your NC for a long time (e.g. months), it is best for battery longevity to have the battery partially discharged-not full, not empty-while it is being stored.

                   We have a color nook and it was near empty. We plugged it in to the charger and it melted. We called B&N and they said it's under warranty and they are sending a replacement charger.  OK, good temp fix, but this belongs to my son.  I don't want him to be burned in the future and I certainly don't want a fire in my home.

                    I have a different problem, my charger connection that goes into the nook color has been loose and now broke. Has anyone else had this problemI don't like the fact that you have to have the charger from B & N, so now I just have to wait.

                      • Re: Nook Color Charger issues

                        This is me.  I just got my Nook in June & by August the charger was falling apart.  This thing wasn't cheap.  It and all of its parts, should last more than two months.  :smileysad:

                            I have had my NC since November 2010 when they first came out. My first cord lasted until just before Christmas. Since the I have "babied" my cords and now I'm on my SIXTH. Yesterday I went into B&N and asked one question..."Does the new Nook Tablet have the same cord as the NC?" They said it does so I am not buying one. I have several electronic gadgets but never have I had to replace even one cord. It is unconscionable for B&N to come out with a new product with a known defect.

                                I guess I've been fortunate that my NC cord still works great (despite some kitten-tooth marks).

                                 

                                Without a careful inspection, my NT cord looks the same as the NC cord (although some have reported it is sturdier).

                                 

                                If it would relieve the frustration, you can use a traditional microUSB cord and it will still charge. It is much slower (maybe 5% an hour), but works well if you plan to leave the device plugged in overnight.

                                    FInd a high output (1-2A) wall adapter and you should be able to let it charge overnight with the screen off using any microUSB cable. It will do better if you top it off periodically instead of letting it drain completely. Once it's dead, it takes a while before you can use it again.

                                     

                                    Is the wall adapter broken, or the NOOK cable?

                                      Mine broke after a couple of months too.  I was very disappointed with the quality of the charger that came with my color nook.  My cell phone charger works and so does the cell phone charger I have in my car.

                                    I have had that problem. The portion of the charger that goes into the nook Color just broke apart. I took it back to the store and asked for a replacement and they gave me another one.

                                      • Re: Nook Color Charger issues

                                        I hate to burst everyone's bubble, but it is a design flaw with the wires connecting into the nice plastic housing that breaks apart when trying to charge your nook color.

                                        I am on my second nook color and am waiting for my fourth power cable to be sent to me.

                                        The online chat yesterday with B&N support was just a lot of hot air.   They know there is a problem with the power cords failing to charge the nooks.   My question:  Is anyone at B&N really looking for a solution or do the customers just have to continue to struggle through with this problem?

                                         

                                        I gladly told the online chat person I would post on facebook and here.   Save yourselves the headaches and don't recommend the nook to anyone.   It is a waste of time to complain to B&N when I truly do not think they are working on a solution.

                                         

                                        I regret buying the nook color because of the hours spent contacting customer service, sitting on hold and going into the store to get assistance.

                                         

                                        If anyone every reads the manuals on any of their appliances with power cords, it clearly states not to wind the cord to prevent the wires from fraying.   If you remember how the cord is packaged on original purchase and how replacements are mailed - the cord is coiled!    Good way to keep the problem alive and kicking.

                                        Today I head to B&N for my 3rd charger in less than a year for the same problem.  It falls apart where it meets the nook.  First I thought it was because I was reading the nook with the charger plugged in and it put pressure in that area.  The 2nd one I was extremely careful with and it did the same thing last night.  Piece of crap.  They need to fix this problem.

                                          I have had my Nook Color less than a year and have had 3 cords!  It gets expensive but the B&N clerk told me the base of the Nook where the cord attaches is very sensitive and I should not hold/read it while charging to save the cord.  That doesn't work for me when I'm tryng to finish a book. Was this a built in problem to make you replace the cord?  Why would it be that sensitive when obviously you are holding the Nook to read,

                                          2 weeks ago

                                          Ok ok... so here's my story: I bought my NOOKcolor back in December, I noticed the problem as soon as I plugged in my nook and the charger just wouldn't go in all the way and it was only charging if i held it at a certain angle. I figured I was doing something wrong so I went to my Barnes & Noble store and the associate I talked to gave the charger a good shove and miracle of miracles, it started working perfectly. I figured I just had to show a little tough love to my nook so despite my fears of destroying the charger port I followed the associates example. It worked that way for a couple of months and then I noticed the charger getting loose and finally just bending, and breaking. Still thinking it was my fault, I went back to my B&N store and bought a new charger. And guess what????  IT HAPPENED AGAIN!!!  And those things are not cheap... Ughhh... So I called B&N  NOOkcolor support and they say they are sending me a new charger. I am very suspicious of these chargers now. Has anyone had a similar problem or am I just having a string of unfortunate events?

                                           

                                          p.s.

                                          Also at the very top right corner of my screen it looks like I have some dead pixels... those were there the very first time I turned my nook on... they don't look dangerous, but still. I feel like I was jipped.

                                          If you check back to the beginning of this forum, you will find an unsettling, scary number of posts regarding charger/cable failure. There are not as many posts on the general forum but there are some. I recently contacted CS because mine also failed like yours. CS immediately offered to send a new cable to me and did not want the old cable returned. I have had my NC only since Dec. so still under warranty. My concernis when replacement cable fails--and I have no doubt that it will--I will have to pay for the replacement. These cables have a design flaw which needs to be solved and then all our lemon cables should be recalled and replaced--before they ruin our NC which will be a much more costly replacement

                                                Purchased my Color Nook November 2010 and approximately 6 months later the charger connector failed (bent and broke).  Felt like it was my fault but found out that I could get a free replacement from Barnes and Noble by calling and giving them my serial number off my Nook.  Wasn't too hassled by customer service and it was free.  I knew it was only a matter of time that the replacement would fail and it just did.  I have treated it very carefully and never read the Nook while it charged.  I am totally disgusted with the design flaw of this charging unit.  I will never buy another Nook.  Will be trying to get another replacent charger but doubt they will send it for free.  They need to recall these and apologize for ripping off their customers.

                                                  I'm on my 3rd charger.  First one was very hard to get into the nook and eventually just go so loose that it wouldn't charge at all.  B&N customer service did send me another charger, which took 3 weeks to arrive; the one they sent me is fraying at the cord/plug and is no longer charging.  I purchased another one last night online and hopefully will get it sooner than 3 weeks.  I have researched this and found that the charger is a major problem but can find nothing fro B&N about a solution other than "replace the charger".  Is anyone aware of B&N action on this obvious flaw?

                                                      also, i got a cover and it came with a wall charger and a car charger but neither will charge it. im not sure why? does the charger have to be the nookcharger with the little 'n' on it? i need to get a new one but the brand name ones are a bit pricey to be just a charger.

                                                          Off brand chargers will work with the NookColor but only if their output is high enough.  Likely the output of the charger you bought was not.  I fell into that trap, too.  Often sellers will advertise NC compatible because they do not know the difference but you must look at the specs to be sure.  I bought two inadequate car chargers before I realized sellers couldn't be relied on.  Read the specs.  It must have an output of 1.9a.  If they don't specify, don't buy.  

                                                           

                                                          Hope this helps.

                                                        The chargers will fall apart no matter what you do. I leave my charger on the counter and never read with it attached to my NC. When it's charging, it is on a flat surface and is easy to plug in and out (once you get the hang of it). I think mine lasted 6 months, then I found it in pieces on the counter. I think maybe the heat from charging makes the hard plastic brittle.
