There are 15 types of sockets used around the world. A-Type And Type B are used in the United States, Canada, Mexico and Japan; Type C is common across Europe, South America and Asia; E-Type and F-Type are found across Europe in places like Germany, Russia and France; Type G is used in the UK, 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 generally not covered by universal adapters, such as India (Type D), Israel (Type H) and South Africa (Type M or N). You will need to purchase specific plug adapters for these locations. To avoid any surprises when you land, check which type you need before you travel.
If you’re only visiting one destination, a basic plug adapter that caters to one plug type is all you need. For trips to multiple destinations or for frequent travelers, a universal travel adapter may prove more versatile. The universal adapters we recommend here have the advantage of including multiple USB ports for charging multiple mobile devices from a single outlet.
