You may hear about different types of plugs now and then. Travelers often have to deal with different plug and outlet types in different countries. But even without leaving the country, you may find that certain tools and appliances require different plug and outlet types as well. Here’s what you need to know about plug “types.”

From A to O

The International Trade Administration (ITA) assigns a letter to different plug types. The letters themselves don’t mean anything other than to differentiate different plugs from each other. They list fifteen types of plugs, so the list goes from Type A to Type O.

Each “type” comes with a description of the number of pins it uses, whether it’s grounded, and what types of amp and voltage requirements it serves. For example, Type C plugs have two cylindrical pins, and see a lot of use in Europe.

Why are There Different Types?

You may wonder why there isn’t a single standard for plugs and outlets around the world. The answer to that is a little complicated. As the need to connect appliances to an electricity supply grew, different countries figured out their own way to do it.

Since international travel wasn’t happening as much in the past, this wasn’t much of a concern. Consider that people traveling to different countries with their own electronic devices is a relatively recent thing.

Because most countries were left to deal with their own people’s electrical needs, there wasn’t much standardization occurring. As a consequence, it’s now far too costly to completely switch an entire country over to a new plug and outlet type.

Things Are Slowly Changing

Things are slowly changing when it comes to outlets and plugs. Many countries are offering options that can accommodate multiple plug types like type c plugs, as well as varying voltage needs. Adapters are becoming more universal and convenient. There’s also newer technology that can help offset the need for an electrical outlet altogether, such as USB and wireless charging.

In the end, don’t let talk of “types” throw you off. If you see “Type C,” you’ll understand it just means a different type of plug and outlet. Now you know different places have different plug and outlet requirements. So, it’s not hard to figure out which you will need.
