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

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

Both Sao Tome and Principe and Bulgaria use Type C/F 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 Bulgaria (230V, 50Hz) are identical. You shouldn't need a voltage converter for your electronics.

Don't forget that Bulgaria hotel rooms sometimes have a universal shaver socket in the bathroom, but these low-wattage outlets aren't suitable for high-draw devices. For reliable charging, use the standard wall outlets with a proper adapter.
