The table below summarises the plug types, voltage and frequency of electrical current in both Algeria and Nigeria.
|Plug Types||C, F||D, G|
|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?
In Nigeria there's more than one socket type in use. You may require more than one adaptor.
The voltages found in Algeria (230V) and Nigeria (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Algeria and Nigeria is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
