In the United States, the electrical grid is set up differently - instead of our 230 V, 110 V sockets work. For this reason, appliances bought and imported from the USA will not work here, they also have a completely different plug. Never mind. Just get an adapter that changes the 230 V input voltage to 110 V output voltage. Adapters from TIPA.EU can power virtually any device from the Czech mains. Changing 230 V AC to 110 V is not a complicated science. The adapters are lightweight, portable, durable and easy to use. Just plug into a Czech socket and plug your American appliance into the adapter. Solved.
