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