The short answer
Europe runs on 230 volts, about twice US voltage. Phone and laptop chargers usually handle this and need only a plug adapter. Most of the continent uses the two-round-pin plug (types C and F). The UK, Ireland, Malta and Cyprus use the three-flat-pin type G. Switzerland uses type J, and Italy also uses type L.
Plug types by country
- Types C and F (two round pins): Spain, Germany, Greece, Croatia, Montenegro, Turkey, Norway, Sweden, Finland, Iceland, Netherlands, Austria, Hungary and Estonia.
- Types C and E: France, Belgium, Monaco and the Czech Republic. Plain C plugs fit E sockets too.
- Italy: C, F and L. Portugal: C, E and F. Denmark: C, E, F and K.
- Type G (three flat pins): UK, Ireland, Malta and Cyprus. Gibraltar uses C and G.
- Switzerland: C and J. A slim two-pin C plug fits; many thicker plugs do not.
Voltage
- Europe is 230 volts at 50 Hz. Gibraltar and Cyprus are listed at 240 volts.
- Check the label on your device. If it says 100 to 240V, you need only a plug adapter.
- US hair dryers, curling irons and CPAP humidifiers may need a converter. Ask your cruise line what the cabin outlets are.
- Many ships have both US and European outlets in cabins.
