Solomon Islands.

220 V · 50 Hz on Type I, Type G.

Australian-pattern Type I is the standard socket at 220 V, 50 Hz, with British Type G also recorded, mainly in older or commercial buildings. Visitors from Australia or New Zealand usually plug straight in; everyone else needs an adapter, plus dual-voltage support for anything rated 120 V only.

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.
