The table below summarises the plug types, voltage and frequency of electrical current in both Angola and India.
|Plug Types||C||C, D, M|
|Frequency of electrical current||50Hz||50Hz|
Angola uses Plug Type C.
In India there's more than one socket type in use. You may require more than one adaptor.
India also uses Socket Type C, which is used in Angola. If using an appliance that has a Type C Plug in the Type C Sockets of India, you will not need an adaptor.
The voltages found in Angola (220V) and India (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Angola and India is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
