You should be fine, but double check the back of the charger just to be sure. It should say something along the lines of “Voltage 100 – 240V, 50 – 60 Hz”. Most of Europe uses a 220V @ 50 Hz, compared to the US at 110 @ 60 Hz. The charger can accommodate any of these inputs so long as you have the converter to plug it into the wall.
