The table below summarises the plug types, voltage and frequency of electrical current in both Algeria and Guinea-Bissau.
|Plug Types||C, F||C|
|Frequency of electrical current||50Hz||50Hz|
In Algeria there's more than one plug type in use.
What type of plug does your appliance have?
No adaptor needed
Guinea-Bissau uses Socket Type C, which is the same as the plug type of your appliances from Algeria. You will not need an adaptor.
You will need this adaptor:
Socket Type F
(Algeria) to Plug Type C
The voltages found in Algeria (230V) and Guinea-Bissau (220V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Algeria and Guinea-Bissau is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
