My new Galaxy came with a charger that seemed to accomodate different tips, but the only one I got was the 120 plug for use in the U.S.
When I'm traveling with devices that charge through the USB cable like this one does, I just use a small inverter that plugs into the cigarette lighter outlet (I'm dating myself here) that has a USB connector on it. I got mine at Harbor Freight for under $10 but they're all over the place.
