Do I need a power converter for Indonesia?

What is a power converter for an Indonesian power outlet?

A power converter enables travellers to use a 100-120 volt electric device with a 220 volt Indonesian power outlet.

Also known as: electrical converter, electrical transformer, voltage converter, power transformer or voltage transformer.

What is the difference between a power converter and a power adapter for Indonesia?

An expensive and heavy power converter converts a 220 volt Indonesian power outlet to work with a non-220 volt appliance, whereas a more lightweight and smaller power adapter (or plug adapter) will change the shape of the plug on your device to fit into a power outlet found in Indonesia. [3] [AD]

Do I need a power converter for Indonesia?

When you are visiting Indonesia from a different region please ensure the device can be charged using a 220 volt power supply.

  • A step down power converter is needed if you are travelling to Indonesia from a country that uses 100-120 volts and your device or appliance won't support 220 volts. Read our WikiConnections world power outlets guide to discover which voltage your country uses.
  • You shouldn't need a power converter if you are already using either a single voltage device that works with 220 volts or one that is dual voltage.
  • Devices designed to use a lower voltage (such as 110 volts) and used in a 220 volt outlet run the risk of an electrical fire hazard, a blown fuse or damage to your device.
  • You won't need a converter if you need to charge a smaller electrical device such as a mobile phone or laptop as these are normally designed for international use and dual voltage, however you should always always check the device for dual voltage support first.
  • For supplying power to appliances which draw more power or generate heat (for example clothes irons and hair dryers) then you will need to use a more expensive higher wattage heavy duty power converter.
  • Buying a smaller robust dual voltage travel appliance could be more practical and cost effective than bringing a much heavier power converter just to use your existing domestic appliance.

How to convert 220 volts to 110 volts

  1. Use a step down power converter to allow you to use a 110 or 120 volt appliance with an 220 volt Indonesian power outlet.
  2. If the power converter doesn't include the correct shaped plug then it will also be necessary to plug in the power cord from the power converter into a power adapter for Indonesia before plugging that into an Indonesian power outlet.
  3. Some power converters include the ability to perform both step up and step down voltage conversions, therefore it may be necessary to manually switch the converter to output the voltage to the 110-120 volt range.
  4. Plug your appliance into the converter and turn the power on, your 110-120 volt appliance can now be used with an 220 volt Indonesian power outlet. [4] [AD]

The best method to tell if your device is dual voltage is to look for a sticker on the supplied charger or on the unit itself, typically on the rear or near to where the power cord goes. This location might depend on the make or model of your unit but could also be written on the box or in the instruction manual.

  • Single voltage devices might have a specific number - such as 240V.
  • Dual voltage devices will say a large voltage range separated with a slash - such as 100/240V.
