Both of these are a possibility with exceptions.

The transformer would work for small loads. But for a substancial load, you will need a very large and heavy transformer. I have one that can convert 190-240 to 120V @ 18A which I was thinking of using, But I would not want it in the car...It weighs almost 80lbs!!

A voltage doubler is a boost circuit really, The boost circuit is just controlled a bit better. The power factor correction is needed for high power charging also because without it, you will be loosing a considerable amount of power that you could be putting into the batteries.
