I just bought a nook tablet and I adore the thing. I will be doing some traveling (15+ hours) and bought a portable rechargable battery with 4k amp-hour capacity and an amperage rating of 1.5A per usb port.
I noticed the nook charges verrrry slowly when I connect it- probably because the nook charger is designed for a 2 amp input. My question is: Is the tablet charging slowly becaused of the reduced amperage input, or because it detects that it is not hooked up to an official nook charger?
I ask this because I found a 10KaH battery on amazon that delivers a full 2 amps per usb port, and if this will give me a quicker charge, I may swap the chargers out.

I do not know the answer; however, my understanding is that the Nook cable has two additional (non-USB standard) pins that deliver the additional current. So, I would guess that any device that does not supply power to these two pins will only deliver the standard USB charging rates.

Unless the USB port on the 2 amp battery can connect to the additional pins on the Nook cable, I doubt the extra current will be transmitted to the Nook.Edit - Sorry j-andersonjma, looks like I was composing my response as you were posting yours.
