A bit of history... why so many plugs?

When electricity was discovered and the first electrical appliances began to be used, each country developed its own plug and outlet design. The industry advanced very quickly and no common global standard was developed.

Therefore, each region adopted the design that seemed best according to their own needs and preferences. For example, in the the United States the flat plug design became popular because it was easier to manufacture industrially. On the other hand, in the United Kingdom the round three-pin plug was created because it allowed incorporating a fuse for greater safety.

European countries adopted round designs partly due to the influence of the British model. Also because this design prevents them from easily coming out of the outlet. In Japan the polarized and grounded plug was created to make them safer against shocks.

Thus, each place adopted the plug that best adapted to its own technologies, safety needs and aesthetic preferences. Without global coordination, this diversity of national and regional designs explains the multitude of plug types present today.
