hello guys
when i charge my nook with nook's charger ..... the charger become too hot till i feel that my usb connector gonna melt ...... i dont know why .... anyone expert in hardware staff???
thx
Do you have another micro-USB charger you can try? The NST doesn't need the official Nook charger. I've been using my phone's charger with no problems for months.
If another charger also heats up, then I'd worry about your Nook. If not, then I'd worry about your Nook charger.

can u specific me an charger ,,,,, thx
Any charger with a micro-USB plug will work. Here's a generic one from Amazon.
Any standard micro USB to USB cable will charge your nook device. Most power transformers that have a USB output will work, also - I charge my nook off of whatever's to hand. My memory is that the NST chargers are 1 amp or so, but if they don't have access to that much current, the NST will charge a bit slower.
Also, you can use your computer's USB port to charge a nook touch (or a nook color/tablet, but the latter two will charge very slowly that way)
If there's really a problem with the device, rather than the charger, that might make trouble -it wouldn't be the first thing to recommend since it could make trouble for your USB port or your PC as a whole.
Some warming of those transformers is fairly normal, though - I see it with my phone and with my LCD nooks, moreso when they are mostly discharged before I start charging them.
Something is wrong there. Nothing should be getting hot to the touch.
As previously said, try another charger or a USB cable connected to a computer.
Is your Nook still charging correctly? Does it get to 100%?
You can look at the battery actual voltage a few different ways.
UsbMode can show you, so can this command in ADB:
Code:
am start -n com.android.settings/.BatteryInfo

u r right .... nook charger is about 1 Amp consumption .... also it's charge nook too fast .... between i charge nook from computer it's become too slow also take about 4 hours or more to become 100% , and the thing make me sure that nook charge till the led turn from orange to green

To prevent your Nook from mounting as a Mass Storage Device when you plug it into a PC, do this:

I have had no success using an external battery charging my 10.1. I have the New Trent duo that allow charging at .5mA and 1A. I was hoping that amperage would register with the tablet to allow charging -- unfortunately this is not the case. Is there any way to make this tablet charge via external USB charging or is it fully locked out like the computer usb?
I guess what I am getting at is what is the limit before this thing will charge like the wall mount

it kinda does, but kinda doesnt charge via usb. it will do it when the tab is locked or off at a very small level but it is enough to keep it alive and even give it some more life when not in use
I clarified my question a bit... I understand there is a trickle charge to some degree if the unit is off but with a full amp pushing through from the battery I would have thought the tab would register...
Did some searching on this and I'm not seeing any related threads. I'm on the latest stable CM7 on my rooted Nook Color. My battery dropped pretty low while playing around with it so I plugged in the USB to my computer. The charge % kept going down. Then I used the wall charger -- same thing.
It's on wifi and I'm streaming music.
I would expect drain while charging isn't quite right. Anyone experience this?
I found my issue. I was using a different cable than what was supplied with the Nook. Using the OEM cable has it charging the right direction..

The NC's manual even mentions this -- the one that comes with our NCs put more power into the NC as it's charging. A regular cable will just barely charge the thing, if you use no apps and the screen is on - so it takes forever. Start doing things, and it goes in the other direction. The NCs cable has extra pins, too.
Kind of a pain, to tether ourselves to one microUSB cable for the NC, but that's the way it goes, I guess.

Yup, I also think though, it will be like the ipad. _IF_ your usb port can give >1 amp of charging, then it should be able to charge your nook _IF_ the screen is off. It will be slow (take 10-12 hours), but still an option. Where are the proprietary charger is 3-4 hours.
My experience with the cable is that you _NEED_ to use their charger to get the full effect. I have used 2, thirty party 2 usb power chargers with the b&n cable and charge really slow (8 hours).
Had an interesting experience with my Nook Color today. Thankfully, didn't turn out to be a bad one, but it seems like it could have been.
I plugged my Nook Color USB cable (and the device, of course ... running CM7.1) into my iPod USB charger cube, the one that wasn't recalled (green dot). After about 15 minutes, the light on the Nook USB cable was multi-color blinking, and the USB cube was burning hot to the touch.
Now, I of course didn't expect it to charge the NC quickly, it's a 500mA to 1A device for charging, where the Nook Color wants 1.8A to charge at full speed. But, I'm wondering if it was trying to push too much power over the cube which could have caused it to overheat and hurt the device.
Thoughts from anyone?

You may have been trying to push too many amps through a single pin. The stock charger and cable use multiple pins to charge at "full speed".
I have done the same thing, hooked the nook up with the nook cable to the iPhone cube charger...it overloads it and shuts down the cube...
...unplug the nook from it, and it will reset (you may have to unplug the cube itself)...then remind yourself to not plug the nook into it.
(I have done it about 3 times so far by accident)
I only take the iPhone charger with me on vacations (or longer periods away from home) and charge both the iPhone and Nook color with it. Never had any problems, aside from the Nook charging slower of course.
It is original charger that came with iPhone 2G, maybe you guys use newer ones? Also my Nook is running stock Froyo if it makes any difference in charging.
It looks like this, not like this.
Has anyone tried using a light for the nook that is powered by the micro USB port?
I haven't found any USB lights with micro USB connectors, but was tempted to buy a laptop USB light and swapping the connector for a micro USB connector.
Plug it into your nook touch and you have light. Of course this will drain your nooks battery faster, but I would hate to have to worry about charging batteries on a reading light in addition to ensuring my nook is charged.
It may be possible, just check if the power drain is not very high, as the USB has a limit of 500 mA (if I am not mistaken). If it works, please tell us.
You will need the USB hack that is on the forum, but I guess there is nothing that would prevent it to work (just maybe frying your USB connection).
Good luck.
You should be able to draw some decent current off the USB connector.
I've pulled >100mA trying to power a hub.
I don't know how much current those LEDs pull but certainly less than that.
It's unfortunate that 2.1 doesn't support reverse portrait or you could have the light at the top!
Light working
Hi. I saw this thread and then I've remembered that I should have an old laptop light so I gave it a go

Nice....I just ordered a plug on amazon at the moment to do basically the same thing. I've got an old light at home that still works.
Plug: http://amzn.com/B005FUNYSA
Have you used it any with the light? How does the battery handle it?
I'm tempted to sell my current Nook Touch and get the one just announced: Nook Simple Touch with Glowlight, IF the Nook powered light isn't great.
Edit: I received the plug, however the light i have doesn't seem to light up off of it. I checked to see that it works off of a USB port on my computer, so I'm not sure if it just wants too much juice or what. I wonder if I need to be rooted, to allow it to work (doubtful, but not sure)...
So, I apparently did something very stupid with my new Nexus 7.
I have a few 1 TB external hard drives, which don't get enough power via an OTG adapter from the Nexus 7 to run. So, I purchased a two into one cable -- that is, a cable that combines two male USB A plugs into one Micro USB B plug so that a USB 3.0 hard drive can use two USB 2.0 ports to have enough power. I had planned to use this to enable use of the hard drives with the Nexus 7 while traveling by plugging one cable in the tablet and the other into a charger.
When I got the cable I tested it by plugging one of the USB A plugs into my Nexus 7, and then I plugged the other into my computer's USB port. The Nexus 7 promptly shut down, the computer complained of a power surge on the USB port, and a distinct smell of melted plastic came from the computer's USB port. I guess the combining cable didn't combine so much as it just acted like a double headed male A USB cable and shorted things out?
The Nexus 7 refused to restart afterwards until I it plugged it into its charger. It works now, mostly. However, if its battery charge is above about eighty-seven percent then it always reports that it is charging, regardless if it is plugged in or not. And if I plug it into a computer while it is reporting that it is charging I have to restart the tablet to get it to connect to the computer -- I guess it thinks it is connected to a charger and doesn't bother checking for a data connection unless restarted.
The level where it stops thinking it's charging varies somewhat -- I've had it still claim to be charging all the way down to eighty-two percent charge, and by repeatedly opening the battery app over and over again I have been able to get it to notice that it's really not charging all the way up to ninety-one percent, but no higher, and I have to open and close the battery app an increasing number of times for every percent that it goes up over eighty-seven before it will notice it's not charging.
Any idea what kind of damage I'm looking at? How to fix it? Whether I can get the warranty people to fix it free of charge? If yes, whether they will send me a new one or just fix the one I have? Whether it's worth getting fixed since it mostly still works, and doesn't really bother me as long as it doesn't get worse?
Nothing?
Nothing from anyone?
Try replacing the internal USB plug? About $25. Easy to do your self.
