What are the plugs like in Thailand?

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

In this sense, you will not have any problems with your electronic devices, as the plugs in Thailand are compatible with the devices from Cuba.

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

It is important to know that in Thailand the electrical voltage is 220 V, with a frequency of 50Hz. In Cuba, the electrical voltage is 110 V and the frequency is 60Hz.

Due to the large voltage difference, you will need to use a voltage converter to use your devices in Thailand. However, it is important to mention that nowadays many electronic devices (such as mobile phones) are dual voltage, in which case a converter would not be necessary. In the Frequently Asked Questions section, we show you how to verify if your devices are dual voltage.

Frequently Asked Questions

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

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

If you are travelling from Cuba to Thailand, you will be able to charge your iPhone or Android mobile device without any problems. Nowadays, these devices are designed to work with wide ranges of voltage and frequency. Additionally, since both countries use compatible plug types, you will not need an adapter in Thailand to charge your iPhone or Android.

Can I plug in my laptop charger in Thailand?

If you are travelling from Cuba to Thailand, you will be able to charge your laptop without any problems. Nowadays, laptops are designed to work with wide ranges of voltage and frequency. Additionally, since both countries use compatible plug types, you will not need an adapter in Thailand to charge your laptop.

Can I use my hair dryer or straightener in Thailand?

The truth is that you have to be careful with products like hair dryers or hair straighteners, because they are generally not dual voltage. Since the voltage difference is so great between Cuba and Thailand, we recommend buying a voltage adapter to be able to use your hair dryer safely in Thailand.

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 Thailand with a different voltage than your device.

What happens if I connect a 110 V device to a 220 V socket without an adapter?

Under no circumstances should you attempt to connect a 110 V device from Cuba to a 220 V socket in Thailand without a voltage adapter. Doing this poses a great danger and the device could cause a fire. Before travelling to Thailand, 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 Thailand 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.
