ALSO, just in case this is all relevant - I'm looking at one of the chargers I would use to plug a labtop into the powerstrip (which I would initially plug into the vibe), and I'm seein' an INPUT of 100-240 V, 1.5 A and an OUTPUT of 19.5 V and 3.34 A.I guess another important detail I sort of allude...

just to be clear, the car would be running while using the 2 labtops. And I would consider driving the car a bit (with everything unplugged) just to be safe (as not to end up losing all battery power and not being able to start the car).

I'm thinking about plugging about 2 labtops and a wireless router in. Would this be possible? And, how about other cars in general.. could I use some sort of convertor to turn the cigarette lighter outlight into a power source - and then would that also be able to support at least 2 labtops?
