Could it be that the Color Nook does not use a standard MicroUSB charger?
I tried to charge my Color Nook today using a BlackBerry charger. But, it was not recognized and the system said "not charging." The charger is fine, as it does charge by BlackBerry. And, the outlet is fine as I plugged in my Nook charger and it charged.
If this is the case, I WILL return my Color Nook. I have a habit of losing chargers. So, I actually bought a dozen MicroUSB charges and leave one at my house, office, travel bag, fancy case, etc. It is great, but apparently not for this.
Solved! Go to Solution.

It does not use a standard micro USB port according to the PC Magazine Review:
From the article:
"Make sure you bring your charger wherever you go. Although the Nook Color looks like it has a standard micro USB port, it will only charge with the Nook AC adapter. I tried both 5V and 10V adapters, with no luck. Nor can you charge the device by connecting it to a PC. Turns out the cable that comes with the Nook Color has a few extra pins in it, to enable faster charging. The custom connector supports 2000mAh charging, whereas most mobile electronics use 500mAh chargers. This is limiting, since it significantly reduces your charging options, but it isn't much different than the proprietary charger that's required with the iPad."

It probably will drain faster than it's charging if you use it while it's charging this way, however. Also, the documentation warns that using any other type of charger (like the one that comes with the original Nook) could damage it. I doubt this is really true, since it is probably just delivering 5v just like the USB port, but be forewarned.

There's a silly trend in economics that forces you to use proprietary connectors and chargers. The manuacturers know that people lose these things , and so are forced to spend stupid money on replacements. Simple, simple economics. I made the mistake of purchasing a Sony digital camera with a proprietary USB connector. It will cost me 38 bucks to replace it if I lose it.
IMHO, this is another reason, I will not migrate over to the Color, away from my Classic. I can charge with any microUSB charger.

I think what the issue is that you can normally plus any usb into an adaptor to charge. They managed to go all Apple on us by charging $25 for a $3 car adaptor.

Jenn, again, that's the official line but actually incorrect if you read my above post. Go ahead and plug it into a usb port for a few hours, leave the screen off, and come back a while later and check the charge. Mine's gone from 50% to almost 90% in 4 hours or so.

NOOKcolor has a custom connector that is compatible with usb connectivity.
While the NOOKcolor connector may appear the same as a microUSB connector, the connector is slightly longer supporting a second set of pins dedicated for charging at a higher rate for a higher capacity battery (when compared to Nook and other mobile devices). As a result the NOOKcolor connector will NOT work in other typical microUSB ports.
However you can use a microUSB connector on the NOOKcolor to sync data from a PC/MAC, but not for the fast charging provided by your dedicated NOOKcolor cable. When the screen is active, NOOKcolor draws more power than the USB is able to provide. Using the device while plugged into USB will cause the battery to drain less slowly. If the screen is inactive (and it's not playing music or Pandora), then the device will charge, but just not as fast as it would charge with the NOOKcolor cable/charger..
Hope that clears things up.

It isn't really economics. The USB standard will not allow any device to pull more than 500mA. So, to get acceptable recharge times, manufacturers are forced to go proprietary. My HTC Fuze will charge via micro-USB, but it takes hours and hours. So, just like the Nook Color, they provide a proprietary charger that gets the job done much faster.
Unfortunately, the manufacturers haven't gotten together and figured out a standard extension to micro-USB that allows interoperability, but it isn't the case that all these manufacturers said "let's go into the charger business".

Jenniisme - Why would anybody read the instructions?
FYI, just because the instructions state to only use their own "whatever", it rarely means the generic doesn't work just as good. In this case though, only the OEM will work.

If I plug the Nook Color cord into my iGo Green wall charger's USB charging port, the Nook Color charges, If I plug the Nook Color cord into the iGo charge anywhere it will power the Nook Color. But the iGo line of power supplies is designed for charging only.
Powering off the Nook Color seems to let lower powered power sources charge the Nook Color.
Now use of a different cord may be an issue because of some special wiring within the Nook Color cord.
This policy maybe why the Nook Color has issues when used in the EU. The EU is trying to establish a limited number of power tips for charging cell phones.
B&N may not replace the Nook Color if they can show you did not use their power cord and power supply.

Doesn't anyone ever read the instructions?
Nookcolor can only be charged by the charger it came with.
It came with a manual??? I just pulled it out and started playing with it...
Seriously though, I have never pulled the manual out of the box.

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 Nook special micro-USB cable, a normal/standard micro-USB cable, a mini-USB cable, and finally an ipod/ipad USB cable..... So, one heavy duty AC adapter for USB & all the different cables.
