What Thailand socket type will you encounter? Thailand uses several outlet types, and understanding them helps you know whether you need a plug adapter.
Thailand Outlet Types Explained
The official Thailand socket type is Type O (three round pins), but most Thai outlets are hybrid designs that accept multiple plug formats:
| Socket Type | Pin Configuration | What Plugs Fit |
|---|---|---|
| Type A | Two flat parallel slots | US/Japan flat-pin plugs |
| Type B | Two flat slots + ground hole | US grounded plugs |
| Type C | Two round holes | European plugs |
| Type F | Two round holes + grounding clips | European grounded plugs |
| Type O | Three round holes (Thai standard) | Thai appliances |
Key point: Most Thai sockets are “universal” style that accept Types A, B, and C. This means US and European plugs often work without an adapter. UK plugs (Type G) never fit.
Types A and C are most common in hotels and homes. Many Thai outlets are multi-type sockets that accept several plug formats.

Do UK Travellers Need an Adapter?
Yes. UK plugs (Type G – three rectangular pins) don’t fit Thai sockets. You’ll need a UK to Thailand adapter.
Many UK travellers use a universal adapter that works in Thailand and other countries.
Voltage and Frequency
- Voltage: 220V
- Frequency: 50Hz
This matches the UK (230V, 50Hz), so most UK devices work fine without a voltage converter.
Check your device: Look at the label on your charger. If it says “100-240V” you’re fine anywhere. If it says only “230V” or “120V” you may need a converter.
Do You Need a Voltage Converter?
Usually no. Most modern devices (phones, laptops, cameras, tablets) have universal voltage chargers (100-240V). Just plug in with the right adapter.
Possibly yes for: Hair dryers, curling irons, and older electronics that aren’t dual-voltage. Check the label.
Where to Buy Adapters
