The Type J plug has two round pins as well as a grounding pin. Although the Type J plug looks a lot like the Brazilian Type N plug it is incompatible with the Type N socket as the earth pin is further away from the centre line than on Type N. However, Type C plugs are perfectly compatible with Type J sockets.
