In one video they show their laptop is using 1.3 watts to play back a standard def video, while the intel equivalent is using 12 watts, which my laptop takes about 17 watt. That would probably be at something like 12v or 16v maybe (my laptop is like 16)? So that would be like 82 mA vs 750 mA. Or with an 1800mAh battery, about 22 hours vs 2.4 hours.
