Preparing for international travel = researching the confusing world of international outlets.

There aren't good visuals for how widely used certain plug types are. So I made my own. Looking at what countries use what outlet types wasn’t enough, I wanted to see how population of those countries affected the popularity.

Weird facts:

• C (and E and F which are the grounded versions) is nicknamed the europlug and the most popular worldwide. C outlets are becoming illegal in favor of E and F styles which fit the same plug, but are grounded.

• D is used in India and Nepal. D plugs are among the most dangerous ones in the world because the prongs are not insulated.

• I is used mainly in China and Australia. It was easier for Australia to manufacture a plug with flat prongs, which lead to the adoption of this type.

• G is used in the UK. And lots of places that England has ruled.

• N is only used in Brazil. Where it works with types of voltage in the country, which isn’t always listed. Which is really scary and dangerous.
