Guinea.

220 V · 50 Hz on Type C, Type F, Type K.

A 220 V 50 Hz grid on round-pin sockets: Type C is the everyday standard, with Schuko Type F and, unusually for the region, Danish-style Type K also recorded. A europlug fits all three. The supply is famously unreliable, so surge protection and patience are as important as the adapter.

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.
