The table below summarises the plug types, voltage and frequency of electrical current in both Singapore and Nigeria.
|Plug Types||G||D, G|
|Frequency of electrical current||50Hz||50Hz|
Singapore uses Plug Type G.
In Nigeria there's more than one socket type in use.
You will need this adaptor:
Socket Type G
(Singapore) to Plug Type D
Nigeria also uses Socket Type G, which is used in Singapore. If using an appliance that has a Type G Plug in the Type G Sockets of Nigeria, you will not need an adaptor.
The voltages found in Singapore (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 Singapore and Nigeria is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
