That entirely depends on how often you use it. I had mine in my car for about 9 days w/out using it and it was only at 50% battery life.

The color uses a micro USB cable but the power source at the plug-in side is much larger and more powerful (1.9A for the nook color vs. 850mA for nook vs. 500-650mA for standard USB power). I tried to plug my regular nook charger into my nook color but without the larger plug in power box that comes with the nook color, it will not charge. In B&N customer help books for nook color they say specifically not to use a power source other than one that is made specifically for nook color. I didn't push the issue once I saw my nook color wouldn't show a charging icon when plugged into my regular nook AC source cord.
The charger may be faulty, the charger port pins broke
nope the nook is much smaller than the nook color! dah!
My nook color... I've never had a nook color so your question is moot.
