Traveling is fun (everyone would agree) but packing for your trip, applying for a visa, figuring our driving conditions, and electricity (plug socket types) and global internet is not so much fun. Right?
We understand your pain. As we travel around the world and try to make sure we have a perfect preparation and packing checklist, alas, it seldom happens. But there is good news for you today. We have compiled and made notes for you to help you decide what kind of adapters you might need for your next international trip.
Plug Socket Types
There are currently 15 types of electrical outlet plugs in use today, each of which has been assigned a letter by the US Department of Commerce International Trade Administration, starting with letter A through letter O. Total 15 different socket types. (Sigh.)
Check out the World Standards website for a global map showing the spread of the different plug types used around the world and a detailed list of the countries of the world with their respective plug and outlet types, voltage and frequency. Fun, right!
