Check the charger, if the charger says 100-240V you probably do not need one, also check the Hertz (Hz) information (also printed on the charger). This site has good information on the Voltage and Hertz for many countries.

DescriptionIf you are using a voltage adapter [I think they mean voltage "converter"] to work outside the US, you may have difficulties charging the battery and other power anomalies.
