Saint Martin.

120/220 V · 60 Hz on Type F, Type C.

The French half of a split island, wired European-style with Type F sockets that accept Type C europlugs — but on a Caribbean 60 Hz supply rather than Europe's 50. The IEC records both 120 V and 220 V service, so check what a given outlet delivers before connecting anything voltage-sensitive; the Dutch side next door runs American-style outlets.

The voltage window

A nominal 120 V supply may legitimately sit anywhere between 108 and 132 V (±10%); 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.
