Frequently Asked Questions

Can I charge my iPhone or Android mobile device in Sao Tome & Principe?

If you intend to travel from Liberia to Sao Tome & Principe, there’s a chance you'll need a plug adapter to recharge your iPhone or Android. Although today's phones are equipped to work with a broad range of frequencies and voltages at present.

However, it’s good to know that the two locations employ some socket standards that don’t match. For this reason, you could need an adapter in Liberia to charge your mobile device for types A and B, while you wouldn’t need one for types F.

Besides needing a socket adapter, you will also need a power converter, since the voltage standards in Liberia and Sao Tome & Principe have different and incompatible power ratings and frequencies.

This means that, although you can physically connect your device using an adapter, because voltage in Liberia is 120 and 220 V and in Sao Tome & Principe is 220 V; so you run the risk of causing damage unless you have a power transformer, since the power levels in both nations do not match and can be harmful for your gadgets.

Apart from requiring an adapter, it will also be necessary to have a power frequency converter, because the power systems in Liberia and Sao Tome & Principe operate on different and incompatible electrical frequencies.

This implies that, even if you can physically connect your gadget with a plug adapter, because the frequency in Liberia is 50 and 60Hz while in Sao Tome & Principe it is 50Hz; so you face the danger of harming it if you don't use a power transformer, since the frequencies in both countries differ significantly and can be harmful for your gadgets.

Can I plug my laptop charger in Sao Tome & Principe?

If you plan to travel from Liberia to Sao Tome & Principe, you will likely need a travel adapter to power up your laptop charger. While most laptop chargers are built to work across different electrical settings these days.

Still, it’s good to remember that certain socket types in Sao Tome & Principe might differ from those in Liberia. As a result, you would want to have an additional adapter for types A and B, but you won’t have to use one for types F.

Apart from needing an adapter, you will also require a voltage converter, because the power systems in Liberia and Sao Tome & Principe differ significantly.

This suggests that, even though you manage to plug in your charger via a socket adapter, the voltage in Liberia is 120 and 220, while in Sao Tome & Principe it’s 220. In the absence of a transformer, there’s a risk your electronic equipment due to the incompatibility in standards.

On top of requiring a socket adapter, you must additionally use a frequency stabilizer, since the electrical frequencies in Liberia and Sao Tome & Principe use distinct and non-matching frequencies.

This means that, even though you are able to plug in your device with a plug adapter, the frequency in Liberia is 50 and 60Hz, while in Sao Tome & Principe it’s 50Hz. Without using a proper stabilizer, you risk damage with your device due to the variation in electrical standards.

Can I use my hair dryer or hair straightener in Sao Tome & Principe?

If you are going from Liberia to Sao Tome & Principe, you will probably need a plug adapter for your hair dryer or straightener. Even though most of these appliances can adapt to various power configurations.

However, the plug types used in Sao Tome & Principe may not match those in Liberia, meaning you’ll require a travel adapter for types A and B, but types F will not require one.

Besides needing a plug adapter, it’s necessary to have a voltage converter for your hair dryer or straightener. The voltage levels in Liberia and Sao Tome & Principe are incompatible, meaning that using your appliance without a converter might harm your device.

For instance, the voltage in Liberia is 120 and 220, while in Sao Tome & Principe it is 220. Without a voltage converter, there is the possibility of overheating to your hair dryer or straightener due to the difference in power output.

In addition to using a plug adapter, it’s advisable to have a frequency converter, as the power frequency in Liberia and Sao Tome & Principe vary. This is particularly important for appliances like hair dryers or straighteners, which rely on specific frequencies to function correctly.

For example, Liberia uses a frequency of 50 and 60Hz, while Sao Tome & Principe operates at 50Hz. Not using a frequency converter could lead to malfunction to your styling tools due to frequency differences.

How can I tell if my electrical device is dual voltage?

If you’re not sure whether your electrical device is dual voltage, the easiest way to confirm the tag often printed on the power cord. Keep an eye out for a range of voltage numbers marked on the device, such as “100-240V” or “110-220V”. When it shows a set of numbers separated by a hyphen, then it’s compatible with multiple voltage standards. Otherwise, if it only shows a single voltage like “110V” or “220V”, your device is not dual voltage

Take into account that in Liberia the voltage is 120 and 220, while in Sao Tome & Principe it is 220, which means that you must have a gadget that works with both voltages. In case your appliance isn’t dual voltage, you’ll definitely require a voltage adapter to operate it safely.

Without a compatible device or converter, it’s likely that your device will get damaged due to the voltage difference.
