A plug adapter for France typically features two round pins and is compatible with Type C and Type E outlets. The Type C adapter (the standard European "Europlug") has two parallel round pins. The more robust Type E adapter used in France also has two round pins but includes a specific female hole at the top; this hole is designed to receive the male earthing (grounding) pin that protrudes from French wall sockets. The body of the adapter is usually circular or rectangular and made of white or black plastic. France operates on a 230V supply voltage and 50Hz frequency. If you are traveling from the US or Canada (110V), ensure your device is "dual voltage" (marked 100-240V). If it isn't, you will need a voltage converter in addition to the plug adapter, as the high French voltage can damage single-voltage electronics. Most modern laptop and phone chargers are dual voltage and only require the simple pin adapter.
