Sri Lanka Power Plugs, Wall Sockets & Electrical Outlets
In Sri Lanka, power plugs and sockets (electrical outlets) of Type G (BS 1363, three rectangular pins in triangular pattern, grounded) are used. Wall sockets run at 230V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Sri Lanka.

Sri Lanka Travel Adapter Guide
A Sri Lanka power plug follows the British Type G standard, meaning travelers from most of Europe, North America, and Asia will need an adaptor to connect their devices. This BS 1363 design features three rectangular pins in a triangular pattern, with a longer earth pin that opens the socket-outlet's protective shutters before the live and neutral pins make contact. Sri Lanka's electrical system runs on 230V at 50Hz, so understanding both plug shape and voltage compatibility matters before you pack.
Is a Voltage Converter Necessary?
Since Sri Lanka operates on 230V at 50Hz, a voltage converter is only necessary if your appliances are built for a different voltage range and lack dual-voltage capability. Most modern electronics such as phone chargers, laptop power supplies, and camera battery chargers are designed to handle a wide voltage range automatically. For these devices, a simple travel adaptor to physically fit Sri Lanka's Type G electrical outlet is all that's required, not a converter.
Dual-Voltage Devices and Sri Lanka
Dual-voltage devices, which typically accept anywhere from 100V to 240V, work seamlessly in Sri Lanka without any need for a converter. Check the fine print on your charger or appliance label; it usually reads something like 'INPUT: 100-240V, 50/60Hz.' If your device meets that spec, you only need a plug adaptor to match the Type G pin configuration used throughout the country.
Do You Need a Travel Adaptor for Sri Lanka?
Yes, unless your home country also uses Type G plugs, you will need a travel adaptor to connect your devices to a Sri Lankan electrical outlet. The Type G plug's triangular three-pin arrangement won't fit into sockets designed for other regional standards, so a compact adaptor that reshapes your plug's pins is the practical solution. Because Type G plugs often include an internal fuse for protection, a well-made adaptor should preserve this safety feature rather than bypass it.
- A universal or Type G-specific travel adaptor for your devices
- Confirmation that your electronics are rated for 230V, 50Hz or are dual-voltage
- Awareness that Type G plugs are bulkier and may block neighboring sockets on power strips
- A surge-protected power strip with a single Type G adaptor if traveling with multiple devices
Frequently Asked Questions
Yes, most visitors will need a travel adaptor since Sri Lanka uses the Type G plug standard. Unless your home devices already use Type G plugs, an adaptor is essential to physically connect to the local electrical outlet.
Pack a Type G travel adaptor to match Sri Lanka's three-pin socket-outlet design, along with any devices confirmed to handle 230V at 50Hz. If your appliances aren't dual-voltage, you'll also need a voltage converter.
Sri Lanka uses the Type G plug, the British BS 1363 standard with three rectangular pins in a triangular configuration. This design includes an internal fuse and a longer earth pin that opens the socket's protective shutters for added safety.
Sri Lanka's electrical system operates at 230V with a frequency of 50Hz. Devices not rated for this voltage will require a converter in addition to a plug adaptor.
