What is the electrical voltage in Poland?
Electricity in Poland is 220volts, 50 Hz AC. The electrical outlets require Type C European plugs (with round pins). Sometimes you’ll find Type E plugs – but Type C plugs also work in these outlets so you are fine if you have an adapter that will work for the Type C plug type. If bringing appliances from the US, or other coutries, please make sure that they are rated for Polish voltage and make sure that you have the appropriate adapter (a good source for travel adapters is igo.com). If your appliance is not rated for the voltages/current in Poland, you may need a transformer.
