What voltage and electrical fittings do I expect in Bhutan?

Bhutan’s electricity is 230 Volts, alternating at 50 cycles per second. You will need a voltage converter if your device does not support 230 Volts at 50 Hertz. Electrical outlets in Bhutan accept 3 types of plugs: three round pins arranged in a triangle, two round pins and two parallel flat pins with ground pin.
