Thailand: Plugs, Voltage & Frequency
Type A/B/C/F · 230 V · 50 Hz
Thailand uses Type A, Type B, Type C, Type F plugs and runs on 230 volts at 50 Hz. This guide covers what the sockets look like and exactly what you need to power your devices there.
Plug Types in Thailand
- Type A — Type A is the flat, two-blade North American plug. The blades are parallel and unpolarized, with no ground pin.
- Type B — Type B adds a third round grounding pin below the two flat blades of Type A.
- Type C — Type C is the classic Europlug: two round pins, ungrounded, used across most of Europe and beyond.
- Type F — Type F (Schuko, German) has two round pins with side earth clips and is grounded.
Voltage and Frequency
Thailand operates on 230 V at 50 Hz. Wall outlets deliver this as standard mains power. USB chargers and most modern electronics accept a wide input range, but always check the rating printed on your device.
Traveler Note: Adapter or Converter?
You need a Type A plug adapter to fit Thailand's sockets. Because Thailand supplies 230 V, appliances built for 100-120 V need a step-up voltage converter unless they are dual-voltage 100-240 V, which most phone and laptop chargers are.
Frequently Asked Questions
Do I need a voltage converter or just an adapter for Thailand?
You need a Type A plug adapter for Thailand's sockets. A voltage converter is only required for devices that are not dual-voltage: Thailand runs on 230 V at 50 Hz, so single-voltage 100-120 V appliances need a step-up converter and 220-240 V appliances need a step-down converter. Most phone and laptop chargers are 100-240 V and need only the adapter.
What plug type does Thailand use?
Thailand uses Type A, Type B, Type C, Type F. You may encounter more than one type in hotels and older buildings.
Can I charge my phone or laptop in Thailand?
Almost certainly. Phone and laptop chargers are normally rated 100-240 V and only need a Type A plug adapter, not a voltage converter. Check the INPUT line on the charger to confirm.
