United States Virgin Islands.

110 V · 60 Hz on Type A, Type B.

As a US territory, the Virgin Islands wire exactly like the mainland: Type A and B flat-blade sockets at a nominal 110 V, 60 Hz. American visitors plug straight in. Europeans need an adapter and dual-voltage equipment, since 230 V-only appliances will not run properly here.

The voltage window

A nominal 110 V supply may legitimately sit anywhere between 99 and 121 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.
