There are 15 plug types in use across the world. Type A and Type B are used in the US, Canada, Mexico, and Japan; Type C is common across Europe, South America, and Asia; Type E and Type F are found across Europe in places like Germany, Russia, and France; Type G is used in the United Kingdom, Ireland, and a handful of other places; and Type I is used in Australia, New Zealand, China, and Argentina. Universal adapters tend to cover all of these types.

Some countries are not usually covered by universal adapters, such as India (Type D), Israel (Type H), and South Africa (Type M or N). You’ll need to buy specific plug adapters for those places. To avoid any surprises when you land, double-check what type you need before you travel.

If you’re visiting just one destination, a basic plug adapter that caters to one plug type is all you need. For trips to multiple destinations or for frequent flyers, a universal travel adapter can prove more versatile. The universal adapters we recommend here have the bonus of including multiple USB ports for charging several mobile devices from a single outlet.
