Sri Lanka: Plugs, Voltage & Frequency
Type D/G · 230 V · 50 Hz
Sri Lanka uses Type D, Type G 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 Sri Lanka
- Type D — Type D has three large round pins in a triangular layout (old British BS 546), still common in India and nearby countries.
- Type G — Type G is the British plug: three rectangular pins in a triangular layout, fused and grounded.
Voltage and Frequency
Sri Lanka 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 D plug adapter to fit Sri Lanka's sockets. Because Sri Lanka 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 Sri Lanka?
You need a Type D plug adapter for Sri Lanka's sockets. A voltage converter is only required for devices that are not dual-voltage: Sri Lanka 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 Sri Lanka use?
Sri Lanka uses Type D, Type G. You may encounter more than one type in hotels and older buildings.
Can I charge my phone or laptop in Sri Lanka?
Almost certainly. Phone and laptop chargers are normally rated 100-240 V and only need a Type D plug adapter, not a voltage converter. Check the INPUT line on the charger to confirm.
