Samoa to Sao Tome and Principe: Complete Plug & Adapter Guide (2026) Adapter Needed

Getting ready for your journey from Samoa to Sao Tome and Principe? Electrical compatibility is easy to overlook, but bringing the wrong plug or forgetting an adapter can leave you scrambling at your hotel. Here's what you need to know.

Your Samoa plugs (Type I) won't fit Sao Tome and Principe's outlets (Type C, F). You'll want to grab a universal travel adapter or one specifically designed for Sao Tome and Principe before you depart.

The voltage and frequency in Sao Tome and Principe (230V, 50Hz) are the same as Samoa (230V, 50Hz), so your appliances should work without a converter.

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.
