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)...

Last night I had a low battery. The screen was on and I hit the side power button to turn it off and nothing happened. The screen just stayed on. After several attempts to turn off the screen it turned off all together. I assumed the battery died. This morning I plugged it into my mini to micro adapter, which I have used before, and it still wouldnt do anything. No charging lights or anything. Tried three different mini USB cables and two different micro adapters. I get nothing on any of them. Are there supposed to be any lights on the phone while it's charging when the phone is off? I really doubt it's the chargers but I suppose it's possible. Does it sound like the phone is dead? Is there anything to check?
I would pull the battery out to force your phone to reset. Plug it in to the charger and and turn it on.
Tried removing the battery several times, still no luck. Today is the 31st day. If it's the phone, AT&T better replace it with a brand new one!
I held the battery from my fuze up against the Focus terminals and pressed the power button. It turned on. So apparently the battery is flat and not charging for some reason. Will try with the original charger when I get home.

You weren't using the original charger before? That's probably why you're having issues. I've had significant issues with it charging with any cable other than what came with it. No clue why.
Figured it out. I have 3 old HTC phone chargers (120v to mini usb) so I bought a bunch of the micro to mini adapters for $1 on ebay. http://cgi.ebay.com/Motorola-Mini-U...230750?pt=PDA_Accessories&hash=item41546be29e
When I use the old charger with the adapter, it will not charge. It does on my gf's HTC Surround though so I will give the wall plugs to her. When I use the new EBAY adapters with a standard usb cable plugged into a computer it works fine. They also work fine plugged into the included 120v to USB adapter. I also bought a couple generic 2 port 120v to USB adapters, http://cgi.ebay.com/NEW-2-Dual-PORT...694149?pt=PDA_Accessories&hash=item2eb1df4185 ,
and they too work fine with a standard USB cable and the ebay adapters. It's really odd. I'm not sure what the difference is inside the 120v to mini vs. the 120v to standard USB but it was consistent amongst all of them.
I had my HD2 USB adapter at my bedside for charging my HD2. Instead of changing the adapter to the new Focus supplied one, I just plugged in the Focus to the HD2 one. In the morning my phone was dead. HD2 Adapter will NOT work, no matter what I try. I even tried my wife's iPhone adapter, and same thing. Went to the Focus Adapter, and all is good now. Strange...
Also, USB Cable to PC works fine.
PS: I read somewhere that the phone will not charge if it's turned off. Have not tested the theory, but maybe related.
I don't get the charging issue. I found out today that my phone wouldn't actually charge with a stand alone micro charger that came with one of my old BT headsets. Seems to work just fine with my car charger using the provided cable but it still makes no sense.
It's only 4 pins and a ground how the hell do you screw that up?

There are no lights anywhere to indicate that the phone is charging (other than the AMOLED screen). So, you have to check before the screen turns off. No LEDs to indicate a missed call or SMS, either - pretty annoying.
Another thing I noticed, when using the aftermarket wall-plug to USB adapter, even with the Samsung cable (USB to micro) allthough it does charge, the touch screen is very very sluggish. Takes several fast swipes just to get the phone to unlock. Can barely even type a word. This also occurs on my GF's HTC Surround. Weird indeed.

That makes it sound like a software issue since it's two different manufacturers.
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.
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 recently purchased an n9005 (note 3) second hand. Everything was fine except it looked like the charging module was on the way out. It wasn't inclined to charge at all with the usb3.0 connector and I had to wedge the usb2.0 connector at an angle. ordered up a replacement charging module - and swapped it out.
All good ...or so I thought!
A few weeks later and the phone shows as 'charging' but it may or may not be charging in reality! I always leave it charging overnight - but now I simply don't know whether I'll wake up to it being completely flat or charged.
I'm not at all sure whats at play here - but it's definitely not the same problem as I had with the charging module. There's no necessity to have the cable inserted at an angle or anything like that.
other than confirming that, I'm at a loss as to what's at play. Could it be some sort of android issue...or....could the battery itself be on the way out?
Any troubleshooting steps or suggestions would be very welcome.
I was away over Christmas/New Year - in Spain. During that time, I recharged using the old micro usb cable - via the mains - and also via a power bank. With both, there was no charging issue whatsoever.
When I came back home, I tried to charge via the mains (with the micro usb cable and the usb 3.0 cable) - but same issue.
Is it possible that the charging module that I bought online and installed - is geared towards continental power supply only - and not the irish power system?
In the meantime, I've simply been charging the power bank up - and in turn, charging the phone via the power bank.
