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

The voltages found in Czech Republic (230V) and Hong Kong (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 Hong Kong is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
