Using UK Iphone Charger in Kefalonia (Greece)?

Has anyone charged there IPhone 4 in kefalonia- Greece?
I was just wondering do I need a voltage converter/transformer to change the voltage for the charger?
Or do I just need the plug adapter to change it to 2 pin.
Just wanna make sure I don't blow my phone up!

All of Europe, including Greece, uses 230 volt, (small deviations up to 240 are allowed.)

Besides, most modern phone chargers can handle 100 to 240 without problems.
Check on the plug part of the charger, or on its box if it is separate, there's likely a text that has the line "100/240 volt" but it might be "100 to 120 and 220 to 240" too.

If this message is there you can use it world wide with only a plug adaptor and should never be used with a converter.

All you need is the 2 pin adaptor.
