How to turn any usb cable into a power only cable.
The idea would be to cut a small usb extension cable in half and put about six feet of two conductor cable 18 gauge between them much less voltage drop than the 24 26 gauge power cord in the cables.
While a device cable has data and power only the power from the extension is carried through.
The inner pair is for data.
We want to remove the middle pair and leave the outer pair.
Are the 10k pull up resistors the right value to let the nook know this is a charger only cable.
The outer two are for power.
Please note that due to limitations of 500ma output from a usb port some devices may take longer than others to charge.
