An F-plug is a type of plug used in some countries, particularly in parts of Europe. It is also known as a Schuko plug, named after the German standard “Schutzkontakt”. The F-plug has two round pins with two metal plates on the side for the grounding function. This type of plug is used for outlets with two round contacts and a grounding contact.

The F-plug is mainly used in countries such as Germany, Austria, the Netherlands, Belgium, Luxembourg, Poland, and various other European countries. It is a common plug type for household appliances and electronics with higher power requirements.

It is important to note that the F-plug is not the same as the G-type socket used in the United Kingdom. Although both have round pins, the placement of the pins and the grounding function differ between these two types.

If you travel to a country where F-plugs are used, it's important to ensure you have the appropriate plugs and adapters to safely connect your electronic devices to the outlets.
