But I've been thinking, I use a hacked cable to charge my Nintendo DS on the road using a USB charger, why not hack the barrel tip of a PSP charger and splice that into a USB cable (first grounding the data lines of course, like I did with the USB cable I use for my DS). It would be no different than this cable mod for the PSP itself.

In fact, I think I will try to assemble that this weekend. I have a 3-week holiday in Thailand coming up and I would love to take just the one USB charger for my blackberry, DS, and PRS-505.
At this point I don't think it's just a matter of getting the right voltage to the pins, it appears to be something in the Reader itself that requires a legitimate usb connection (likely handshaking on the serial lines) before it will allow charging.

But do let us know!
