In Bali, the common type of electric socket is Type C, which has two round pins. The voltage in Bali is 230V with a frequency of 50 Hz. Most countries use a voltage of 220-240V, so if your countrys normal voltage is within this range, you can use your electric appliances in Bali without needing a voltage adapter. However, if youre from the US, Canada, or most South American countries, you may need a voltage converter in addition to a power adapter. The Bali power plug is also a standard European plug, so if youve traveled around Europe before, you can use the same plug. The typical wall adapter for a two-pin plug is seen in the image above. You might need a plug adapter in Bali due to the 2 pin socket and plug arrangement (e.g. if you come from the UK). If youre already in Bali, you can purchase one for a few dollars at any store.
