In France, there are two associated plug types: types C and E. Type C is the plug which has two round pins, and type E is the plug which has two round pins and a hole for the sockets male earthing pin. Type E is more common in France and throughout the country. It is important to note that travel adaptors do not convert the voltage or frequency, so if the appliance is a single voltage rated appliance, it will need to operate at the same voltage as the supply voltage of the country, which is 230V in France. If this is not the case, a voltage transformer or converter should be used to allow the appliance to work safely and properly.
