Compatible With
When Traveling TO Countries with Type J
If you're traveling from a country that doesn't use Type J power plugs, you'll need a power plug adapter to physically fit your devices into Type J outlets. Make sure to check voltage compatibility as well - most countries using Type J operate at 230V.
When Traveling FROM Countries with Type J
If you're traveling from a country with Type J to countries with different power plug types, consider a universal travel adapter that includes multiple power plug configurations. This will work in 150+ countries worldwide.
Common Misconceptions
Type J is compatible with Type F (Schuko) plugs
Type J and Type F look similar but are not mechanically compatible. You typically need an adapter when traveling between Switzerland and most of continental Europe.
Any Europlug will provide grounding in Type J sockets
Type C Europlugs are ungrounded; they fit Type J sockets but do not provide grounding. Only true Type J plugs provide a protective earth connection.
