| Papua New Guinea | St. Vincent (Winward Islands) | |
|---|---|---|
| Plug Types | I | A, C, E, G, I, K |
| Voltage | 240V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Papua New Guinea uses Plug Type I.
In St. Vincent (Winward Islands) there's more than one socket type in use. You may require more than one adaptor.
Socket Type I
(Papua New Guinea) to Plug Type A
(St. Vincent (Winward Islands))
Socket Type I
(Papua New Guinea) to Plug Type C
(St. Vincent (Winward Islands))
Socket Type I
(Papua New Guinea) to Plug Type E
(St. Vincent (Winward Islands))
Socket Type I
(Papua New Guinea) to Plug Type G
(St. Vincent (Winward Islands))
Socket Type I
(Papua New Guinea) to Plug Type K
(St. Vincent (Winward Islands))
St. Vincent (Winward Islands) also uses Socket Type I, which is used in Papua New Guinea. If using an appliance that has a Type I Plug in the Type I Sockets of St. Vincent (Winward Islands), you will not need an adaptor.
The voltages found in Papua New Guinea (240V) and St. Vincent (Winward Islands) (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Papua New Guinea and St. Vincent (Winward Islands) is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
