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

Getting ready for your journey from Singapore 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 Singapore 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 the same as Singapore (230V, 50Hz), so your appliances should work without a converter.

Rather than packing bulky converters, consider buying travel-sized dual-voltage versions of appliances you can't live without. For phones and laptops, all you'll need is the right plug adapter since their chargers almost always support worldwide voltage.
