BTW - my laptop draws 24W while not charging and 33W while charging. I could run 11 laptops at once off this, or 9 charging laptops.
Is that _measured_ consumption or what the manual/label on the laptop says it should use? Also is this on the DC/laptop side of the power supplu, or the AC/mains side?
They seem quite low? My Powerbook maxs out at 45W on the AC mains side of the power supply (according to the probably-conservative label on it). So thats probably 30W used by the laptop, worst case.
