|Thanks for the link, but the info on the site is really cryptic...|
1) It seems that the Notebook adapter only delivers 12v, and that if you need a different voltage you need to use the Nesco adapter (which I already have, so no big deal). Is this correct ?
2) Also by my calculations (not sure about this, my physics courses go back a while...), the GWCP uses a 19v/2.67amps AC adapter, therefore it should run for a minimum of 60/(19*2.67)=1.2 hours with the battery pack, assuming full usage of the available wattage and with no power saving enabled. What's been your experience ?
