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

Traveling from Sao Tome and Principe to Gabon means crossing into a different electrical system. Before you leave, take a moment to understand the plug types and voltage used in Gabon so you can keep all your devices charged and ready.

Both Sao Tome and Principe and Gabon use Type C plugs, so your devices should plug right in. An adapter isn't strictly necessary for this trip.

On the voltage front, Sao Tome and Principe (230V, 50Hz) and Gabon (220V, 50Hz) are very similar. You shouldn't need a voltage converter for your electronics.

When packing for Gabon, 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.
