Sao Tome and Principe.

220 V · 50 Hz on Type F, Type C.

Portuguese-influenced wiring on this Gulf of Guinea archipelago: Type F sockets taking Type C europlugs, at 220 V and 50 Hz. Travellers from continental Europe plug in directly; those with British or North American plugs need an adapter, and 120 V-only gear needs a converter.

The voltage window

A nominal 220 V supply may legitimately sit anywhere between 198 and 242 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.
