The Ninja 300 charging system has a rated output of 294 watts (21 Amps at 14 volts, when RPM's are at least 5000 RPM, according to the service manual (page 1-11). The Ninja 250 charging system was rated at 266 watts (19 Amps at 14 volts, same RPM). Someone put together a DIY that calculated out all of the electrical loads on the 250, and came up with 70 - 88 free watts under most conditions. (link to that thread) I don't think anyone has posted up the math yet for the 300, but odds are it has a similar amount of available excess energy.
