The table below summarises the plug types, voltage and frequency of electrical current in both Angola and Czech Republic.
| Angola | Czech Republic | |
|---|---|---|
| Plug Types | C | E |
| Voltage | 220V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Angola uses Plug Type C.
You will need this adaptor:
Socket Type C
(Angola) to Plug Type E
(Czech Republic)
The voltages found in Angola (220V) and Czech Republic (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Angola and Czech Republic is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
