A pair of amp meters compared the power draw of a standard battery with that of the ultra high speed charger, which pulled 0.55 amps and 5.86 amps, respectively -- at least according to the demo equipment on hand at NTT's CEATEC booth. The model we saw definitely looked very much like an early prototype at this point, and the carrier didn't seem to have any idea of when it may begin to be implemented in handsets and other devices, only committing to a release "as soon as possible." Still, we're pretty excited about the potential here (imagine being able to charge your phone completely with only a quick stop at an airport kiosk), and wouldn't hesitate to pick a battery up -- assuming of course that the final version is a bit more refined.
