Adapter Guide for Each Type
Traveling opens doors to new cultures, foods, and unforgettable experiences. Yet one small but frustrating detail can quickly derail the excitement, and more often than not, it’s discovering your charger won’t fit into the outlet.
Across the globe, there are 14 standardized plug types labeled A through O, each shaped by local needs and history. Knowing the difference can save you a great deal of stress and keep your devices powered wherever your journey takes you.
Why So Many Plug Types?
Electrical outlets didn’t start with a shared blueprint. Each country developed its own design based on safety standards and infrastructure at the time. Some regions leaned toward 110 volts, others adopted 220 volts, and frequency still differs between 50Hz and 60Hz. These choices shaped the plugs and sockets that became standard in each area. And since no single universal agreement was reached, we are left with different plug types across the world.
The 14 Plug Types Explained
Type A & B
Two flat pins (A) or two flat pins with a grounding pin (B). Common throughout North and Central America, as well as Japan.
Type C
Also known as the Europlug, this design has two round pins and is one of the most widely used types worldwide.
Type D
Three round pins in a triangular layout, most often found in India and South Asia.
Type E & F
Both used across much of continental Europe. Type E includes a female grounding socket, while Type F (the “Schuko”) uses grounding clips on the sides.
Type G
Three rectangular pins arranged in a triangle. This sturdy design is standard in the UK, Ireland, Hong Kong, and parts of the Middle East.
Type H
Unique to Israel, it features three pins that form a Y-shape.
Type I
Two flat angled pins with an optional grounding pin. Used in Australia, New Zealand, and China.
Type J
Found in Switzerland and Liechtenstein, it has three round pins including a grounding pin that’s slightly offset from the others.
Type K
Used in Denmark and Greenland. It has two round pins and a grounding pin, similar in look to Type F but wired differently.
Type L
Standard in Italy and parts of North Africa, featuring three pins in a line.
Type M
A larger version of Type D, most commonly used in South Africa.
Type N
Developed specifically for Brazil. It looks similar to Type J with its three-round pin design.
Type O
Found in Thailand, with three round pins forming a triangular pattern.
Other Important Considerations
Knowing the plug shape is only part of what travelers need to think about. As mentioned earlier, power systems around the world vary between 110V and 220V, and frequencies shift between 50Hz and 60Hz. While many devices adjust automatically, not all have that capability, you may need to carry a voltage converter to make sure your appliances work overseas. Check the label on your electronics before connecting them to avoid causing any damage. To find out whether you’ll need a voltage converter or not, check out our voltage converter guide.
