Electricity in the Czech Republic is 220V and AC 50Hz (make sure your appliance like shavers, hairdryers, curling irons, camera chargers, laptops, etc. has a switch to change the voltage to 220!). All sockets have two round female contacts (live left) and round blanking/grounding protecting pin in middle top. If you don’t have adapter you can often purchase one at the airport when you arrive (plugs and adapters are hard to find in Prague shops, so be prepared and buy it at the airport or before you arrive). If you’re visiting from North America you will need a transformer as North America works on 110 Volts and Europe works on 220 Volts.  To see a picture of Czech outlet - click here.

Can I bring my computer (laptop) to Prague?
Most laptops (all new laptops made in last around 5 years) are manufactured with the idea in mind that they might one day be used on another continent and so their power adapters are made to work on both voltage cycles. Look at your power adapter to see if it says 110-240 Volts. This means the laptop will work just fine without a step-down transformer. Incidentally, many digital cameras work the same way.
