Re: PD170 car battery charger

I've used one of these to charge Sony NP-F types from the cig lighter in my truck for years when I'm out in the boonies, also comes with a 120vac->12vdc wall-wart:

If the link doesn't work you can go to B&H and search for a SPM-13

The regular Sony camera charging adapters are 50-60hz and 110-240v and will work just about any where in the world if you're in a hotel or other lodging and have the proper AC adapters.
