Are you useing the cable that came with your nook? Regular usb cables take 7 hours to charge, the nook cabe takes 1-2hours.
The nook cable and hooked to AC adapter charges in a couple of hours. But Nook or any micro-usb hooked to the computer would take that kind of time to charge. As it's the only way I charge mine is plugged into computer overnight.
I guess using a generic usb with AC adapter would be the same as to the computer. As the nook cable has two extra pins for the AC adapter to charge it faster.

From a stone-cold dead NT to full charge, using standard-issue NT cable and charger...4-5 hrs. I don't consider that to be a problem - run the NT into the ground all evening/night, plug it in overnight - ready to go in the morning. BTW, it helps to load an app killer, kill any extraneous apps and turn off wifi when you're charging.

Picked up my replacement 16GB Tablet today at B&N; when I got it home it had a 51% charge on the battery straight out of the box. I plugged the Nook Tablet into the charger/wall and now, almost 3 hours later, the "N" symbol is still orange. I turned the Nook on and the charge indicator under the "Device" section said my Tablet was at 92% power, so the charge light should be turning green any time now. I hope. lol

Thanks for all the responses.
I did check with B&N tech support about the issue and this is what they advised me:
Based on the situation you described we would like to inform you that it takes long time to charge NOOK battery if it is below 20%. If a discharged battery is charged faster it reduces battery service life. It usually takes longer than expected to charge the discharged battery (below 20%), this is mainly to save the battery life of the NOOK.
Avoid deep discharge and instead charge more often between uses, the smaller the depth of discharge, the longer the battery will last. Avoid storing the battery in full discharged state. As the battery will self-discharge over time, its voltage will gradually lower, and when it is depleted below the low-voltage threshold. It cannot be charged anymore because the protection circuit (a type of electronic fuse) disables it.
