Frequently asked

What type of plug does Thailand use?
Thailand uses Type A and Type B and Type C and Type O outlets at 230V, 50Hz.
What's the voltage in Thailand?
Thailand runs on 230V at 50Hz — that's the high-voltage standard. Dual-voltage devices (most phones, laptops, modern chargers labelled "100-240V") work as-is. Single-voltage devices like hair dryers, curling irons, and travel kettles do not without a converter.
Do I need a travel adapter for Thailand?
Only if your home country uses a different plug type. Travellers from any country whose plugs aren't Type A/B/C/O will need an adapter. Use the table above or the calculator to check your specific pair.
