In my particular case, the cooler had a 40W cooling element on it, plus a fan. Let's say the fan uses up an additional 10W. (It's nowhere close, but we'll leave LOTS of slop...) So the cooler is using up 50W of power all by itself. That means it's drawing 4.16A off of the cigarette plug. The marked output of the Durango's aux power outlets are 20A, so that leaves you with 15A (or 180W) to power anything else.

As for your laptop, almost all laptops are actually looking for DC input power. And, almost all laptops are looking for less than 12V input, so it would again be more effecient (if necessary!) to simply regulate the 12V down to whatever voltage your laptop requires. (That's a little more advanced than using an inverter, but not by much.)

BUT, that may not be necessary. Take a look at the charger that comes with your laptop, it should list on it what its power line input requirements are; usually 110V 1A, or something along those lines. That would mean that you'd need 110W to run that charger. (In that case, remember that you only had 180W AFTER the cooler to play with, so you're down to 70W left, and that's if you get a 100% lossless DC to AC to DC conversion.)

If I'm not being clear here, don't hesitate to ask/email and I'll explain it ad nauseum. :)

One question I have is... Are the auxilary power outlets both running off the same 20A fuse, or are the independently fused? (i.e. can you draw 20A off of the rear aux outlet, and another 20A off the front aux outlet for a total of 40A, or can you only draw a combined 20A from both outlets?)
