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 [3] 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.

Do I need a power converter for Indonesia?

When you are travelling to Indonesia from another region please ensure that the device will accept a 220 volt power supply.

  • A step down power converter [4] is needed if you are travelling from a country that uses 100-120 volts and your device won't support 220 volts. Read our world power outlets guide to discover the voltage is used in your country.
  • 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.
  • Normally electrical devices which are designed for a lower voltage (such as 120 volts) and used in a 220 volt outlet run the risk of a blown fuse, damage to your device or even an electrical fire hazard.
  • You won't need a converter if you wish to recharge a smaller electrical device such as a tablet or cell phone as these are normally dual voltage and designed for international use, 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 straighteners) then you will need to use a more expensive higher wattage heavy duty power converter [5] which allows it to be used with a 220 volt Indonesian power outlet.
  • It could be more cost effective to purchase a smaller lightweight dual voltage travel appliance than trying to bring a heavier power converter just to use your existing domestic appliance.
  • For more information read these comprehensive travel guides on using curling wands, clothes irons, hair straighteners and hair dryers in Indonesia , along with recommendations for some affordable dual voltage alternatives.

Do I need a power converter for Indonesia if I'm from the US?

The voltage from a power outlet in Indonesia is different to an American outlet so please bring a step down power converter [4] if your appliance or charger isn't dual voltage.

What converter do I need for Indonesia?

You need a step down power converter [4] which will allow you to use any 100-120 volt appliance in Indonesia.

What is the difference between a transformer and a converter?

Converters and transformers are both used to change one voltage to another, but this ambiguity can cause confusion as their purposes are different:

  • Power converters are designed for simple electrical appliances which typically generate heat or use motors such as clothes irons, shavers or hair dryers. Transformers are designed for more complex electronic items such as televisions or games consoles.
  • Buying a power converter is cheaper than buying a power transformer.
  • Power transformers are larger and heavier making them more suited for permanent residential use; for example an expat wishing to use an imported television would need to use a transformer for this purpose.
  • Power converters are more suitable for travellers wishing to bring domestic appliances abroad such as hair dryers or flat irons. However, it is more practical and cost effective to purchase a dual voltage appliance designed for travel rather than a heavier power converter.
  • Power converters are suitable for 2 pin ungrounded appliances, it could be harder to find a converter if you want to use a grounded 3 pin appliance.
  • Transformers can be used constantly however it is recommended that converters are used for no longer than a couple of hours at a time.
  • Shops may sell transformers under the name of converters, for the purposes this guide we will be referring to both converters and transformers as converters.

How to convert 220 volts to 110 volts

  1. Use a step down power converter [4] 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.

What voltage is used in Indonesia?

Indonesia uses 220 volts in their normal power outlets.

What voltage is my appliance?

Single voltage hair dryer

What voltage is my appliance?

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.
  • Single voltage devices could also have a small voltage range (around 20 volts) with a dash to accomodate small voltage fluctuations - such as 100-120V.
  • Dual voltage devices will say a large voltage range separated with a slash - such as 100/240V.

  3. Power converter - A step up step down power converter converts 110-120 volts up to 220-240 volts and 220-240 volts down to 110-120 Volts, between $90 to $100.
  4. Step down power converter - A step down power converter allows a 100-120 volt appliance to be used in a 220-240 volt power outlet, estimated cost between $120 to $130.
  5. Heavy duty power converter - A 5000 watt heavy duty step up and step down power converter used to convert voltages for domestic appliances, power tools, televisions, heating appliances and motors, under $150.
