A flat two-pin US plug fits most outlets in Thailand, but grounded three-pin plugs may not. Bring a universal adapter to be safe. The voltage is 230 V, so check that your device says 100–240 V.

Outlet types A to O
Guide: 15 IEC types
| Type | What it looks like | Where |
|---|---|---|
| A | two flat parallel pins, no ground | US, Canada, Japan |
| B | two flat pins and a round ground pin | US, Canada, Mexico |
| C | two round 4 mm pins, no ground (the Europlug on most chargers) | Europe, Russia, CIS, parts of Asia |
| D | three thick round pins in a triangle | India, Sri Lanka, Nepal |
| E | two round pins, ground pin in the socket | France, Belgium, Poland |
| F | two round 4.8 mm pins and side ground clips (Schuko) | Russia, Germany, most of Europe |
| G | three rectangular pins, fused plug | UK, UAE, Malaysia, Singapore |
| H | three pins in a Y shape | Israel |
| I | two angled flat pins and a ground pin | Australia, China, Argentina |
| J | three round pins, the ground pin off-center | Switzerland |
| K | two round pins and a D-shaped ground pin | Denmark, Greenland |
| L | three round pins in a row | Italy, Chile |
| M | like D but larger pins (15 A) | South Africa, India, Sri Lanka |
| N | two round pins and a third between them, recessed socket | Brazil, South Africa |
| O | three round pins, Thai standard that also takes the Europlug | Thailand |
The US uses type A and B. If a country has A or B outlets, your plug fits; check the voltage, though, because most of the world runs on 220–240 V.
How to use
- Pick a country and your plug type; the default is the US plug (A/B).
- Right below you get the answer, outlet types, voltage and frequency.
- If it fits only some outlets, bring a universal adapter: your hotel could have any type.
- Open the country page for where to buy an adapter and voltage notes.
Power plugs abroad: FAQ
Where do US plugs fit without an adapter?
Of these destinations: Japan, Philippines. Most other countries use round-pin or British outlets.
Do I need a voltage converter?
Usually not: phone, laptop and camera chargers are rated 100–240 V. Single-voltage 120 V hair dryers and kettles need a converter or a dual-voltage travel model.
Which universal adapter should I buy?
A universal adapter with sliding pins covers outlets A, C, G and I, which is enough for nearly every country. Pick one with grounding and USB ports.
What does 50 Hz vs 60 Hz mean?
The US runs on 60 Hz, most of Asia on 50 Hz. Chargers and electronics do not care; some clocks and motors may run slightly differently.
Which countries use British plugs?
The UAE, Malaysia, the Maldives and Sri Lanka mostly use type G, the same as the UK.
Do US plugs fit in Thailand and Vietnam?
Flat two-pin plugs usually fit the combination outlets there, but the voltage is 220–230 V and grounded three-pin plugs may not fit.
Where does the data come from?
Outlet types, voltage and frequency come from the IEC World Plugs reference by the International Electrotechnical Commission. The check date is on the page.
Where the data comes from
- Outlet types, voltage and frequency come from the International Electrotechnical Commission’s IEC World Plugs reference.
- Plug compatibility follows the IEC table: a flat A plug fits A and B outlets, a thin Europlug C fits C, E, F, H, J, K, L, N and O, a Schuko F fits E and F.
- Where a country has several types, we note which are common. Data checked on November 13, 2026. Older buildings and rural areas can differ; a universal adapter covers every case.
