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

Getting ready for your journey from Sao Tome and Principe to Eswatini? 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.

Sao Tome and Principe uses Type C and F plugs, while Eswatini uses Type M. 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.

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

When packing for Eswatini, 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.
