Guinea-Bissau to Sao Tome and Principe: Complete Plug & Adapter Guide (2026) No Adapter Needed

If you're heading to Sao Tome and Principe from Guinea-Bissau, it's worth checking the power situation before you pack. Different countries use different outlet types and electrical standards, so your devices may not plug in directly when you arrive.

Good news: Guinea-Bissau and Sao Tome and Principe share compatible plug types (Type C). Your existing plugs should fit directly into Sao Tome and Principe's outlets without any adapter needed.

The voltage and frequency in Sao Tome and Principe (230V, 50Hz) are close to Guinea-Bissau (220V, 50Hz), so your appliances should work without a converter.

Most modern phone chargers, laptop adapters, and camera chargers are designed to handle 100-240V input, so they'll work anywhere with just a plug adapter. Heat-producing appliances like hair dryers and flat irons are often single-voltage, so check before you plug them in abroad.
