The output is 5volts / 1.9 Amperes.
Edit, it is written on the charger btw, you could probably have checked that your self

.FYI: I tried using my HTC usb charger with the nook usb cable and it will not charge. The charging light flickers.
There is this cable from boxwave with a dongle off the end that you are supposed to use to charge from USB chargers. Why would anyone need this?

It looks like one end is for transferring data only and the other is for charging only

That looks like it will do the job perfectly and is only $13

It is charging, just not as fast and the device doesn't notify you of it. HTC usb wall plug chargers are usually 5volts and 1amp, the nook requires 1.9 amps to charge properly.

The nook charges when connected to a usb socket on a computer, which provides 500ma as a high power device. So your 1000ma charger is twice as good as using a computer.
In order to get 1900 ma, the nook isn't using stock usb stuff in the charger... but normal usb works just fine because, well, the standard requires it to...
4000 mAh battery should charge fully in 2 hours on the nook charger, 4 hours on the htc charger, or 8 hours on a computer...

The NC will charge from my Droid's power adaptor even though it does not show it to be working. It will take a lot longer to charge with a standard 0.5A USB power adaptor.
It does work. It's just charging slow so you can't necessarily tell. Also. There will be no indicators on the nook to show that it is charging but i'm pretty sure it is. Leave it plugged in overnight and see.
2A rated USB adapter for under $10: http://www.madvapes.com/2-amp-AC-to-USB-Adapter-ideal-for-Passthroughs_p_2357.html
I own one and can confirm it works perfectly.

1Nook charging cable is NOT standard micro USB. If you use standard cable, it will charge with 500mA max and no charging indicator on the screen. The only way to have it fast charge is to use Nook cable.
The charger controller inside Nook looks for Dp and Dm pin at~2V. The resistance between these pins is less than 200Ohm. My DIY charger is made from a powered USB hub with 5V 2A supply. I short Dp and Dm together and tied to 2V with voltage divider resistors. (By the way, Try this at your own risk!!!)1The answer is it depends. Here's the options:
NC, NC cable, NC charger - Life's good, 1.8A charging rate
NC, NC cable, other charger - Depends on the profile and circuitry of the charger, could be 500mA, 1.5A, or 1.8A.
NC, other cable, NC charger - You'd better use a heavier gauge wire, because even though you're not using the NC cable, USB spec says that the device may request up to 1.8A if available. NC will decide what it wants here.
NC, other cable, other charger - You'll get 500mA, 1.5A, or 1.8A, depending on the charger. Again, be careful of amperage on the cable
other device, NC cable, NC charger - *should* work, but I don't recommend it. I think ground carries a high voltage for some reason, since I've seen my USB hubs resetting and sparks coming from the connector at times
other device, NC cable, other charger - this really should work, but you're not going to get faster charge times, since again it depends on the output of the charger. I'd still be cautious since the NC cable has something wierd going on.
other device, other cable, NC charger - Go for it. I've gotten 1 hr full charge times on my phone with this method. You MUST use a heavy enough gauge USB cable.
other device, other cable, other charger - depends on device draw and charger profile mode
