Mexico to Sao Tome and Principe: Complete Plug & Adapter Guide (2026) Adapter Needed
Heading from Mexico to Sao Tome and Principe? Plug types and voltage standards differ between countries, so a little preparation goes a long way. Here's a breakdown of what to expect at the wall socket.
Mexico uses Type A and B plugs, while Sao Tome and Principe uses Type C and F. Since there is no overlap, you will need a travel adapter to plug in your devices. Make sure to pick one up before your trip or at the airport.
Voltage is another key difference. Mexico uses 127V while Sao Tome and Principe uses 230V. If your device only supports one voltage, using it with the wrong supply could cause overheating or permanent damage. Look for "Input: 100-240V" on your charger. Most modern phone and laptop chargers support this range.
A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Sao Tome and Principe specifically, look for one that supports Type C/F outlets. USB charging ports built into the adapter are a nice bonus.
