Sierra Leone.

230 V · 50 Hz on Type G, Type D.

A British colonial inheritance at 230 V, 50 Hz: modern installations use Type G while older buildings keep round-pin Type D sockets. A UK-style adapter covers most hotels, but a Type D adapter is worth having off the beaten path. Grid power can be intermittent, so surge protection helps for sensitive electronics.

The voltage window

A nominal 230 V supply may legitimately sit anywhere between 207 and 253 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.
