Power Plugs and Sockets in Indonesia - Do You Need an Adapter?

In Indonesia, the plug types used are C and F. The voltage is 110-220 V with a frequency of 50Hz. On the other hand, in Costa Rica, the plug types used are A and B. The voltage in Costa Rica is 120 V with a frequency of 60Hz.

Type C

Type F

What are the plugs like in Indonesia?

In Indonesia, the predominant plug types are C and F. If you are coming from Costa Rica, then your devices are of type A or B.

For this reason, you will need an adapter, as the plugs in Indonesia are not compatible with the devices from Costa Rica and you will not be able to use your devices.

Do I need a voltage and frequency converter to travel to Indonesia?

It is important to know that in Indonesia the electrical voltage is 110-220 V, with a frequency of 50Hz. In Costa Rica, the electrical voltage is 120 V and the frequency is 60Hz.

Due to the wide range of voltages used in Indonesia, you will be able to use your devices from Costa Rica, but you should always verify the voltage of the socket to which you are connecting your electrical device. Your chargers will work at 120 V, so you should connect them to sockets of that range.

Regardless of whether you need a voltage converter or not, you need a plug adapter, because the plug types are different in Indonesia.

Frequently Asked Questions

Below we will answer some of the most common questions asked by travelers going to Indonesia.

Can I charge my iPhone or Android mobile device in Indonesia?

If you are travelling from Costa Rica to Indonesia, you will need an adapter to charge your iPhone or Android mobile device. While it is true that nowadays these devices are designed to work with wide ranges of voltage and frequency, it should be remembered that both countries have incompatible plug types, so you will need an adapter in Indonesia to charge your iPhone or Android.

Can I plug in my laptop charger in Indonesia?

If you are travelling from Costa Rica to Indonesia, you will need an adapter to charge your laptop. Generally, these devices are designed to work with wide ranges of voltage and frequency, but it should be remembered that Costa Rica and Indonesia have incompatible plug types, so an adapter is necessary to charge your laptop in Indonesia.

Can I use my hair dryer or straightener in Indonesia?

You will have to be careful when using your hair dryer or hair straightener in Indonesia. These devices are not usually dual voltage, so you should pay attention to ensure that the voltage of the hair dryer/straightener is the same as the socket you are going to use. To be able to use these devices with peace of mind, we recommend that you purchase a voltage adapter.

How do I know if my electrical device is dual voltage?

To know if your electrical device is dual voltage, you must check the label or product specifications. If the label indicates a voltage range, such as 100~240V and a frequency range like 50~60Hz, then your device is dual voltage and can be used without any problems. If your device is not dual voltage, then you will need a voltage converter to be able to use it in sockets in Indonesia with a different voltage than your device.

However, remember that dual voltage only affects the voltage and frequency.Since you are travelling to Indonesia from Costa Rica, you will still need a plug adapter.

What happens if I connect a 120 V device to a 220 V socket without an adapter?

Under no circumstances should you attempt to connect a 120 V device from Costa Rica to a 220 V socket in Indonesia without a voltage adapter. Doing this poses a great danger and the device could cause a fire. Before travelling to Indonesia, make sure you have a voltage adapter.

What happens if I connect a 60Hz device to a 50Hz socket without an adapter?

When connecting a 60Hz device to a 50Hz socket in Indonesia without a frequency adapter, the worst that can happen is that the device may run at a slower speed than expected. Nowadays, most devices are prepared for these small frequency differences, but in older devices, the difference may be more noticeable.
