The table below summarises the plug types, voltage and frequency of electrical current in both Guinea-Bissau and Finland.
| Guinea-Bissau | Finland | |
|---|---|---|
| Plug Types | C | C, F |
| Voltage | 220V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Guinea-Bissau uses Plug Type C.
In Finland there's more than one socket type in use.
You will need this adaptor:
Socket Type
(Guinea-Bissau) to Plug Type F
(Finland)
Finland also uses Socket Type C, which is used in Guinea-Bissau. If using an appliance that has a Type C Plug in the Type C Sockets of Finland, you will not need an adaptor.
The voltages found in Guinea-Bissau (220V) and Finland (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Guinea-Bissau and Finland is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
