The table below summarises the plug types, voltage and frequency of electrical current in both Czech Republic and Niger.
| Czech Republic | Niger | |
|---|---|---|
| Plug Types | E | A, B, C, D, E, F |
| Voltage | 230V | 220V |
| Frequency of electrical current | 50Hz | 50Hz |
Czech Republic uses Plug Type E.
In Niger there's more than one socket type in use. You may require more than one adaptor.

Niger 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 Niger, you will not need an adaptor.
The voltages found in Czech Republic (230V) and Niger (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 Niger is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
