Most current chargers have an input range of around 100-240 Volts, 50-60Hz, but use a strong light and a magnifying glass to be sure. About the only problem you might face is that the plug may not fit the receptacle - you may need a set of plug adapters (they're about the same set all over the world on the receptacle side, but the device side is made to fit the local standard, so buy it in the country you bought the charger for - or look on eBay for a universal plug adapter).
