So what is the charge time like for most people from computer and wall adapter? I haven't charged directly off my computer, at least not from empty, but BN claims 3 1/2hrs. They also seem to claim the same amount in 1 or 2 places about the wall adapter. However, I checked my nook wall adapter, which isn't labeled with its power specs, and it churns out 5.6w from the wall, so I assume it is a 5v 1amp adapter (running about 90% conversion efficiency from 120v mains).

I'd assume with twice the power of a regular computer .5amp USB port, the charge time would be something roughly half that off a computer port.

So if ~3 1/2hrs from a computer, roughly 2hrs from a wall adapter that can manage 1amp.

Does that sound about right? I am still working on the wonky battery issues I am having with my Nook ST, and just trying to get a feel for what a properly working one should manage from a wall adapter. My most recent charge took somewhere around 1:45hrs from the wall adapter and it was hooked up to my computer first for about 10-15 minutes transfering some books and a few new wall papers. That at least sounds like that should be roughly a full charge from zero (it refused to power on any more the battery was so depleted).
