What Plug Does Thailand Use?
View CountryThailand uses mainly the Type C (CEE 7/16 Europlug) with a few Type A, Type B and the Thai Type O sockets. The country supplies 220V at 50 Hz. Most travellers should plan for a plug adapter and visitors from countries with 100-120V supplies should also check device voltage before plugging in.

Do I Need a Travel Adapter for Thailand?
Most hotels and public places accept the two-pin round Type C Europlug, so travellers from continental Europe and India usually do not need an adapter. Visitors from the UK and Ireland, and from Australia and New Zealand, will need an adapter to fit Thai sockets. Travellers from the US, Canada and Japan sometimes need an adapter because some outlets take flat A/B pins but many do not. A compact adapter that fits Type C and Thai Type O, or a small universal travel adapter, covers most situations.

Do I Need a Voltage Converter in Thailand?
Thailand runs on 220V at 50 Hz. If your charger or device is labelled 100-240V, it will work without a converter; many phone and laptop chargers are dual-voltage. Single-voltage appliances such as some hair dryers, straighteners and older appliances may need a voltage converter. Visitors from the US, Canada and Japan should check their devices carefully; travellers from the UK, Europe, Australia, New Zealand and India generally do not need a converter.
Thailand Plugs and Sockets Explained
Type C (CEE 7/16 Europlug) is the primary socket: two round pins, unearthed, very common. Type B (NEMA 5-15) is a minor form you may sometimes see: three pins, two flat and one round earth, earthed. Type O (TIS 166-2549, Thai) is a minor, three round-pin earthed socket designed for Thai plugs. Type A (NEMA 1-15) appears occasionally: two flat parallel pins, unearthed. All operate at 220V, 50 Hz.
Tips for Charging Your Devices in Thailand
- Check each device label for "Input" or voltage range before plugging in.
- Carry at least one adapter that fits Type C sockets, or a small universal adapter.
- Assume hair dryers and straighteners may need a converter or use a travel model rated 100-240V.
- Keep chargers and power bricks off the floor and away from moisture in humid climates.
- Bring a power strip with a single adapter if you have several devices, but check local fuse ratings.
