Puerto Rico.

120 V · 60 Hz on Type A, Type B.

US territory, US wiring: flat-blade Type A and B sockets at 120 V and 60 Hz, identical to the mainland. Mainland American and Canadian devices plug in unchanged; European 230 V-only appliances need a transformer as well as a shape adapter.

The voltage window

A nominal 120 V supply may legitimately sit anywhere between 108 and 132 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.
