In Bhutan, the power plugs and sockets used are of Type D, Type F, and Type G.
Type D plugs have three round pins in a triangular pattern and are commonly used in Bhutan, while Type F plugs have two round pins with two earth clips on the side and are also compatible with Type C sockets. Type G plugs, which have three rectangular pins in a triangular pattern, are less common but may be found in some places, especially in newer constructions or accommodations catering to international travelers.
It's recommended to bring a universal travel adapter to Bhutan to ensure compatibility with various types of power outlets you may encounter during your stay.
