I purchased a generic y-cable for this tablet. It goes by several names, but it's supposed to allow you to power a usb device externally while connected to a tablet. With mine, when I first plug it in it starts charging my tablet. But after about 5 seconds my Fire no longer charges from it. This happens on both Fire OS and CM. Is this normal? Is there someway I can keep my tablet charging while connected to a usb device?

I'd be suspicious of the cable if charging stops with no USB device attached. Also make sure the charging brick can supply sufficient current to satisfy both devices.

Hi,
I bought the nook but live in France. Can i charge my nook with my HTC Desire power supply and cable? The nook usb cable doesnt seems to be "only usb".
Thank you.
You can probably use a standard USB power inverter and generic cable. If it's safe for your Desire, it's almost definitely safe for the NC. However, some cables might randomly not work.
A standard micro-USB and charger will work, but it is slower than the Nook charger. I routinely charge from a powered USB hub at the office.

Ok thank you!
Hi I am also from Europe and I checked that Nook Color have a multi 220/110 voltage charger

You need only plug adapter
Yeah, that what i use for now. As i have my htc power supply alway connected to my wall i wan't to put the NC us power in his box.
I tried one of those cigarette light -> USB adapters for charging the nook in my car. When I plug it in, it wakes up. But it's not charging. Anyone have any idea? I'm using the Nook cable, btw.

It's charging, just slowly. Charging from a standard 500mA USB jack doesn't cause the "Charging" indication to appear in most battery monitors on the NC, but if you leave it there for a while with the screen off and not doing anything you should see the battery percentage go up a bit. It takes about 8 hours for a full charge via USB. It's enough power to either run the NC if you're actively using it OR to charge the battery, not both at once.
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
my kindle wont char plug it in get red light says not chargin pls help
Try using a different outlet or a different usb wall wort.
Make sure that u plugged in the USB Cable direct into the USB Port (dont use a USB Hub).
Are you using a Amazon charger, or at least one when you plug in it does not say you are using a "Low power Charger". My normal cell phone charger can not charge my Kindle Fire. So this may be a reason. If the kindle is under warranty, If you can not get it to charge I would contact them.
Hi there! Well, my fire is running fire nexus ROM, and my problem is that the tablet neither charges nor detects any USB connection. I can use it while plugged to ac adapter but when I run an app with high CPU load it will shut off. It doesn't even show plugged and charging. When I connect it to the computer there is not any notification to choose USB modes. So I cannot revert to stock since it won't be detected and if I use flash fire it might power off and brick it... Is this a hardware issue? Can the charge system be bypassed?

Almost certainly a hardware or cable issue. Swap cables to eliminate the latter. Also look for bent/missing pins in the USB port. Contact Amazon for a courtesy exchange if still under warranty.
I tried many cables, and sent it to repair, but didn't change at all. Thanks for your reply. So I was thinking about a way of charging it externally
Hello guys
I recently changed from S9+ to S21 and I have a question : I usually use my desktop computer to charge my phone during night while I sleep. (with data USB cable)
I have no problem when the desktop is on (under windows) : my phone charge (with USB cable) and I can transfert photos.
When my computer is off, when I plug the phone, the screen show the charging screen for 2 seconds and stops
I have no problem with my S9 to charge when the computer is off. (I know that there is an option in the bios to keep USB charging when computer is switched off)
It looks like the USB power is too low, and the S21 doesn't want to charge with it.
Maybe ther is an option in the phone to authorize this kind of charging ?

There isn't such an option in the OS as of now. It's possible that the S21 battery amp requirements are more than those of S9
Do you think the computer's USB port has a lower supply when the computer is turned off ?
We don't know what kind of computer you have, or what it's USB port capabilities are. That's something you can try to figure out, looking at your computer or manual for the computer's motherboard. Also check the BIOS settings, sometimes you can control the power state of the computer when it is "off" and whether power is still supplied to the USB ports (e.g., to allow the computer to boot up when it detects mouse or keyboard USB inputs).
As an example, my MSI motherboard has a feature where you can install software to set the USB ports to a high power output state, so you can power USB devices using more than the standard output current.
My Dell laptop has a USB port with a special symbol that means it's for high-power output for charging phones etc. So it can handle charging modern phones, and puts out more than 0.5 amps, but only for those USB ports with the special symbol (lightning bolt).
You'll need to just find out more information about what your computer is capable of.
I have a MSI gaming pro carbon X370 ( the optional wake by USB is on, without that, you're right, the USB are totally off and nothing will charge)
I did more investigations .... I tried all my USB cables and all USB ports and finally find 1 combination that works.
Only 1 of 12 USB cables worked ( the one took from an external HDD ) even the original cable supplied with the phone didn't work and nor a 100W Ugreen cable...
And only the front USB work. The different USB directly on the motherboard doesn't work with this phone, despite I always used them to charge many devices...
for information the working cable is a KAIBAO revision 3.0
Finally it doesn't work with this cable : it take longer before the phone stops to charge, but it stops too ...
Hi,
You need to check the power requirements of your new phone.
Thank you.
