Oman to Sao Tome and Principe: Complete Plug & Adapter Guide (2026) Adapter Needed
Getting ready for your journey from Oman 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 Oman plugs (Type G) 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 close to Oman (240V, 50Hz), so your appliances should work without a converter.
When packing for Sao Tome and Principe, bring at least one adapter per room if you're traveling with others. Airport shops often sell them at a markup, so ordering one online beforehand saves money. A small power strip from home can also multiply a single adapter into several outlets.
