You know, if that's all you want to do, it's probably a good idea to see if
somebody makes a car->laptop adapter that would work for you. Going from
12VDC to 120VDC back to 12VDC is probably inefficient, when all you really
need to do is clean up the power, limit the current and maybe change the
voltage slightly. Going from a
transformer->inverter->rectifier->transformer circuit (or is it i->t->t->r?
I dunno) to a single much smaller transformer should be a big win. But
note: I'm not any kind of electronics engineer.
