Basically all chargers today work with 110 and 220 and 50/60 Hz. Just check the label.
Best is to buy a little adapter plug. Sarch on ebay for "power adapter europe" - cheapest are around 1 $ incl. shipping - they come from China, delivery time is 3-4 weeks.
Make sure you get the one with the two round pins for the plug and the rectangular sockets for your cable.
