The table below summarises the plug types, voltage and frequency of electrical current in both Guinea-Bissau and Gibraltar.
| Guinea-Bissau | Gibraltar | |
|---|---|---|
| Plug Types | C | C, G |
| Voltage | 220V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
Guinea-Bissau uses Plug Type C.
In Gibraltar there's more than one socket type in use.
You will need this adaptor:
Socket Type
(Guinea-Bissau) to Plug Type G
(Gibraltar)
Gibraltar 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 Gibraltar, you will not need an adaptor.
The voltages found in Guinea-Bissau (220V) and Gibraltar (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Guinea-Bissau and Gibraltar is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
