Dominican Republic.

110 V · 60 Hz on Type A, Type B.

The Dominican Republic runs North American-style power: 110 V 60 Hz on flat-blade Type A and B sockets. US and Canadian devices work as-is. European visitors need a plug adapter plus dual-voltage gear; it is also worth carrying a surge protector, as the supply can be less steady than the nameplate suggests.

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.
