What plug adapter do I need for Sri Lanka?

In Sri Lanka, you will likely want a travel adapter that works with Type D, Type M, or Type G power sockets. The usual electrical voltage sits at 230V, and the frequency is 50Hz.

Type G, which is the standard UK plug with three rectangular pins, is presently the most common socket you will find in modern hotels and brand new buildings around Sri Lanka. Still, older guesthouses and rural places sometimes keep Type D (three little circular pins) or Type M (three bigger circular pins). Since you might run into this mix during the entire trip, bringing a universal travel adapter is a strong idea for peace of mind. Also, travellers coming from places that use 110-120V, like the US or Canada, should confirm whether their devices are dual voltage. If they are not, you will need a step-down converter to prevent electrical harm to the device.
