Does anyone know the power usage of the car under normal operation? I know the alternator cranks 80 amps but want to find out how much is actually used while driving. And also what the fuse is in the lighter receptacle. And I can't check in the manual b/c mine was stolen.

I want to buy a power inverter but don't want to oversize it and drain my system or overheat the lighter lines. My dream is to:microwave a large can of while driving.....mmmm......
