Global Plug Guide: Plug Types by Country and Essential Adapters

Your laptop, phone, camera, and tablet often do a lot of the heavy lifting when you travel. The problem starts when the plugs and sockets at your destination are incompatible, leaving you unable to recharge without the right adapter. For professionals and frequent travelers, that mismatch can mean wasted time, unnecessary purchases, or unsuitable charging setups.

This guide breaks down the socket types and adapters commonly used across different regions, helping you prepare ahead of departure. With the right setup packed in advance, you can spend less time decoding unfamiliar connections and more time using the devices you brought along.

Plug Types and Voltage (Types A - O)

There are 15 plug standards used around the world, ranging from Type A to Type O. Each differs in shape and pin configuration, while the electrical supply behind the socket can also vary by country. Knowing which plug is used in your destination helps you determine whether your charger is physically compatible with the local socket.

Socket shape is only one part of the equation because voltage affects whether a device can safely receive power. Many countries use a 220 - 240V supply, while countries including the United States, Canada, Japan, and Taiwan commonly use lower-voltage systems. If your device does not support the local voltage, a suitable voltage converter may be required in addition to a plug adapter. The section below looks at the different plugs and sockets used in each region, organized by continent.

Plugs and Adapters Across the World

Asia

Asia features a diverse mix of plug types, with Type C (European), G (British), and A/B (American) being most common. As mentioned before, voltage typically ranges between 220 - 240V, except for outliers Japan and Taiwan, using 100 - 110V.

• Japan (100V): Older buildings favour unpolarized Type A while newer constructions use grounded Type B.

• China (220V): Type I dominates in mainland China, though Type A (US style) persists in older buildings and Type C works in many hotels.

• India (230V): Type D was the traditional standard, now transitioning to Type M (similar but with thicker pins) for heavier appliances.

• Thailand (220V): Unique Type O is the official standard, but US-style A/B and European C are widely accepted in tourist areas.

• Singapore (230V): Follows British colonial standard with robust Type G sockets, identical to Malaysia and UK.

• Malaysia (240V): Uses the same British-style plugs as Singapore but operates at slightly higher voltage.

• South Korea (220V): Officially uses European-style outlets, though some older buildings may feature US Type A/B.

Oceania

The region maintains remarkable consistency with the Australian-style Type I system, though voltage varies slightly between nations.

• Australia (230V): All outlets accept the characteristic angled flat pins of Type I, with mandatory shutters for child safety.

• New Zealand (230V): Identical to Australian standard (Type I), with same plug and voltage specifications.

• Fiji (240V): Follows regional standard of Type I but at higher voltage, with some resorts offering US-style A/B for tourists.

• Papua New Guinea (240V): Shares the Type I standard but operates at higher voltage similar to Fiji.

• Samoa (230V): Recently shifted towards Australian standard, replacing older US-style outlets.

Europe

The continent predominantly uses round-pin connectors, with notable exceptions in Britain, Switzerland and Italy.

• Germany (230V): Type F outlets with side grounding clips are most common, though Type C works for ungrounded devices.

• France (230V): Type E with male grounding pin, though many sockets accept both E and F plugs.

• UK (230V): Utilizes Type G, with distinctive three rectangular pins arranged in a triangular pattern, with built-in fuses for safety.

• Italy (230V): Unique linear three-pin arrangement of Type L, though most sockets accept Europlugs (Type C).

• Switzerland (230V): Type J features a similar round-pin design found in the Type C plug, which can most of the time be accommodated by Type C.

North America

The continental standard remains remarkably consistent, with minor voltage variations.

• USA (120V): Type A is standard for ungrounded devices, while Type B adds ground pin for heavier appliances.

• Canada (120V): Identical to the US system with same plug types and voltage.

• Mexico (127V): Uses the same plug shapes of Types A and B but at slightly higher voltage than its northern neighbors.

• Greenland (230V): Greenland has a total of four associated plug types, being Types C, E, F and K.

• Bahamas (120V): Follows US standard despite being outside North American mainland.

South America

This continent shows fascinating diversity in electrical standards. This patchwork system means travelers may encounter different plugs even within the same country, such as in older buildings versus modern developments.

• Brazil (127V/220V): Transitioning to new Type N standard, though older Type C persists.

• Argentina (220V): Uses Australian-style Type I plugs.

• Chile (220V): Primarily uses Europlugs (Type C) but Italian-style Type L appears in some installations.

• Colombia (110V): Follows US standard with same plugs and similar voltage.

• Peru (220V): Accommodates both US and European styles, with Type C becoming more prevalent as compared to Types A and B.

Africa

Electrical standards often reflect colonial history, creating a varied mix of incompatible systems across the continent. Many countries maintain dual or even multiple plug standards due to ongoing infrastructure transitions and regional variations.

• South Africa (230V): Type M is traditional, while newer Type N is gaining adoption.

• Egypt (220V): Featuring Types C and F, adopting standard European outlets, particularly in tourist areas and modern buildings.

• Morocco (220V): French-influenced system with Type E being the official standard, though Type C works.

• Kenya (240G): British-style Type G outlets identical to UK standard, common across former British colonies.

• Nigeria (230V): A mix of British Type G and older Indian-style Type D, varying by location.

Overview

Navigating the world’s plug systems can feel overwhelming, but understanding these regional patterns makes preparation simple. 

Asia’s mix of Type A, B, C and G requires careful research, especially in transition countries like India and Thailand. Oceania’s uniform Type I system offers consistency, while Europe’s mostly standardized round-pin outlets (with notable UK/Swiss/Italian exceptions) cover much of the continent. The Americas maintain North-South divides, with consistent Type A and B in the north versus South America’s hybrid systems. Africa’s colonial legacy creates the most variability, where even single countries may use multiple plug types.

Universal Travel Adapters

What can you do as a smart traveler? 

At Energea, we recommend packing a reliable universal adapter for greater flexibility across different parts of the world. For example, one adapter can support multiple plug formats, reducing the need to carry several country-specific options or buy a new one at each destination. It also makes it easier to connect to unfamiliar sockets in hotels, airports, and other travel settings.

However, voltage compatibility deserves the same attention. Devices such as laptops and hair dryers may have different input requirements, so check the voltage rating before plugging them in. Otherwise, using equipment with an incompatible voltage can cause poor performance, permanent damage, or safety risks. A quick check before departure helps keep your devices powered and your trip running smoothly.
