Power Plugs and Sockets in Mexico - Do You Need an Adapter?
If you are travelling to Mexico 🇲🇽 from Brazil 🇧🇷, then YES, you will need an adapter.
In Mexico, the plug types used are A and B. The voltage is 127 V with a frequency of 60Hz. On the other hand, in Brazil, the plug types used are C and N. The voltage in Brazil is 127-220 V with a frequency of 60Hz.


Type A


Type B
⚠️ Your devices from Brazil of type C and N will not be valid for any socket and you will need an adapter.
⚠️ In Mexico they use 127 V. Be careful with the voltage difference.
What are the plugs like in Mexico?
In Mexico, the predominant plug types are A and B. If you are coming from Brazil, then your devices are of type C or N.
For this reason, you will need an adapter, as the plugs in Mexico are not compatible with the devices from Brazil and you will not be able to use your devices.
In Mexico, type B outlets are the most common in homes, but type A is also widely spread, with adapters between both types being common. The split-phase system is extensively used, and electricians can wire both type A and B outlets to achieve the 220 V necessary for air conditioning, washing machines, dryers, and other high-consumption products. It is possible to find, although rarely, type G and I outlets in industrial and commercial areas that require the use of imported devices; however, these are not common in the country.
Do I need a voltage and frequency converter to travel to Mexico?
It is important to know that in Mexico the electrical voltage is 127 V, with a frequency of 60Hz. In Brazil, the electrical voltage is 127-220 V and the frequency is 60Hz.
Since Brazil uses a wide range of voltages, you will not have a problem plugging in your devices in Mexico as long as it matches the voltage there, which is 127 V.
Regardless of whether you need a voltage converter or not, you need a plug adapter, because the plug types are different in Mexico.
Frequently Asked Questions
Below we will answer some of the most common questions asked by travelers going to Mexico.
Can I charge my iPhone or Android mobile device in Mexico?
If you are travelling from Brazil to Mexico, 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 Mexico to charge your iPhone or Android.
Can I plug in my laptop charger in Mexico?
If you are travelling from Brazil to Mexico, 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 Brazil and Mexico have incompatible plug types, so an adapter is necessary to charge your laptop in Mexico.
Can I use my hair dryer or straightener in Mexico?
You will have to be careful when using your hair dryer or hair straightener in Mexico. 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 Mexico with a different voltage than your device.
However, remember that dual voltage only affects the voltage and frequency.Since you are travelling to Mexico from Brazil, you will still need a plug adapter.
What happens if I connect a 220 V device to a 127 V socket without an adapter?
Under no circumstances should you attempt to connect a 220 V device from Brazil to a 127 V socket in Mexico without a voltage adapter. Doing this poses a great danger and the device could cause a fire. Before travelling to Mexico, make sure you have a voltage adapter.
