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