Travelling in Georgia you will meet Types C and F sockets, fed with 230 V at 50 Hz. 230 V means no voltage converter – only the plug shape matters.
Handy for multi-stop trips: Kazakhstan, Mongolia, Uzbekistan and Tajikistan use the same plug types. Travelling further to Bahrain, Singapore and Malaysia means a different adapter. In Asia, 17 of 50 recorded destinations use exactly this combination.
Protective earth
Grounded and ungrounded sockets may occur
Mixed supply: Type C without earth, Type F with earth. Which one is in your room only shows on arrival.
