Looks like from the manual the AC wallwart puts out 12v, so...I'm guessing it requires a 12v external power source. That sucks, IMO. But...maybe we'll luck out and it'll run on a broader range, including 9v. And if so, I like the 9v Li-Ion batts marketed for DVD players, a la the Walmart / Lenmar DVD-U9 / Initial RB-270 batts. For 12v power, I don't know of a better solution than lead, unfortunately. But maybe others do...
