Using electrical plug is inevitable in our daily lives. In Indonesia, we call electrical plug as "stop-kontak"/electric socket or "colokan"/plugs. Each country has electrical plug type that is different from other country's, depending on determined standard.
It is better for you to not ignore this thing should you wish to visit Indonesia. Don't let small things, like this one, hamper your activities as you will need some time to find proper adaptors.
In Indonesia, widely-used electrical plugs are type C and F. These types have two pins with rounded tips. Commonly, electrical voltage in Indonesia are 220 volt and frequency 50 Hz. Visitors are suggested to bring converters and adaptors should they come from countries with 110-270 electrical voltage.
