If you need to connect a device – Hydro Asic with a cable with a Chinese plug to the network in the Czech Republic, you will need an adapter that allows you to connect the Chinese connector to the European (Czech) plug. In the Czech Republic, socket type E with round pins is commonly used. On the other hand, A, C, and I type plugs are common in China, so you need to be sure what type of plug your Chinese cable has in order to choose the right adapter.
I recommend purchasing the adapter from a trusted vendor and making sure it meets all safety standards. It is also important to note that the adapter only changes the shape of the socket, not the voltage, so you should check that your device supports the voltage used in the Czech Republic (230-380-400 V).
