I don&#x27;t understand why Brazil in that map is shown as having plugs of type either K or I (the purple one). I have never seen these here.<p>Now, as for the special local mess that we love, types A and B are sort of &quot;legacy&quot; ones and you would find them mostly in power extensions cords and such so people could use imported American electronics in the past. It wasn&#x27;t even unusual for people to take the ground pin out of type B plugs so they would be compatible with other &quot;regular&quot; A plugs.<p>Pretty much everyone has used (or still uses) types C, E and F in Brazil. I would dare to call these de facto standards here. But as the article says we have officially adopted IEC 60906 and as such every new building, house or whatever that has been built in the last few years have this plug everywhere. Not everybody likes them (engineers!) but I think most of the folks in the country simple don&#x27;t give a shit.<p>The thing is that some places [1] mention this standard is type N, but I have been to Switzerland and all my Brazilian IEC 60906 plugs worked 100% in every single try across the country so I would like to know how compatibles are types J and IEC 60906 (well, type N?). They seemed absolutely compatible in every way to me.<p>PS: I have never seen type O in Thailand myself, but perhaps in touristic areas they simply use worldwide known plugs instead or just leave some adapters around? IIRC most of the time I would find the European types of plugs there.<p>[1] <a href="http:&#x2F;&#x2F;www.worldstandards.eu&#x2F;electricity&#x2F;plugs-and-sockets&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.worldstandards.eu&#x2F;electricity&#x2F;plugs-and-sockets&#x2F;</a>
