The table below summarises the plug types, voltage and frequency of electrical current in both Bahrain and Chad.
|Plug Types||G||D, E, F|
|Frequency of electrical current||50Hz||50Hz|
Bahrain uses Plug Type G.
In Chad there's more than one socket type in use. You may require more than one adaptor.
The voltages found in Bahrain (230V) and Chad (220V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Bahrain and Chad is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
