Every country has its own unique power plug and supply voltage that they think is more efficient than the American system. Talks of standardizing the type of plug used were initially pushed back when the Great War and World War II took place. And while a universal standard plug was proposed in 1986, demand for it was not very high; countries had evolved the American Type A to their use and standards and has used it for decades.

International customers will have their respective adapter included with their cooling fans when purchasing from Amazon.
