Plugs, sockets and voltage in Czechia: what adapter to bring

You arrive at your Prague flat, unpack, pull out your phone charger and find that the plug does not fit. Or worse, it fits, you plug in a hair dryer from home, and a small puff of smoke announces the end of its career.

Power in Czechia is simple, but it differs from the US, the UK and a good few other places. Here is what to bring and what to check before you pack.

What plugs and sockets does Czechia use?

Czech sockets are Type E, with two round holes and a pin sticking up from the socket for earthing. The slim two-pin Type C plug, the Europlug, fits them, and it is what most phone chargers use. Earthed appliances need a plug that matches the socket's earth pin, so if you come from elsewhere in Europe and your plug looks different, check before you rely on it.

Plugs from the UK (Type G), the US and Canada (Types A and B), Australia and many other countries do not fit. You will need a plug adapter.

What does 230 V mean for my devices?

Voltage is the more important issue. Czechia uses 230 volts, which is standard across Europe. The US and Canada use around 120 volts. If you plug a device designed only for 120 V into a 230 V socket, it can overheat or fail.

Most modern chargers for phones, laptops, tablets, cameras and e-readers are made for a wide range, typically 100 to 240 V. The label says so: look for "INPUT: 100-240V" on the charger itself. If you see that, you need only a plug adapter.

Single-voltage devices are the problem. Hair dryers, curling tongs, straighteners, electric shavers, small kitchen appliances and travel kettles are often made for one voltage. If the label says only "120 V" or "110 V", do not plug it in without a suitable voltage converter. A cheaper plan is to buy a basic hair dryer or kettle in Prague. Check the label before you pack.

Do I need a converter or just an adapter?

An adapter changes the shape of the plug and does nothing to the voltage. A converter or transformer changes the voltage. For a device marked 100-240 V, you need only an adapter. For a single-voltage device, you need a converter, but converters are bulky and not all are suitable for heating appliances such as hair dryers. In most cases it is simpler and safer to buy the appliance locally.

A travel adapter with several plug types is convenient if you move between countries. A single-purpose adapter for Type C and E sockets is fine if you only come here. Check that it has the earth connection if your device is earthed. Buy a reputable one: the cheapest unbranded adapters are a poor place to save money.

What about frequency?

Czechia uses 50 Hz. The US and Canada use 60 Hz. For most modern electronics, this makes no difference. Some older devices with motors or clocks, such as certain record players or mains-powered clocks, may run at the wrong speed. Check the label or manual.

Where can I buy an adapter in Prague?

Adapters are sold at airports, railway stations, electronics shops, large supermarkets and hardware stores. Prices vary and tourist areas are typically more expensive, so if you arrive without one, buy it at a large shop away from the centre. Our guide to getting from the airport to the city covers the first journey. The rest of the first-week jobs, including a local SIM, are in your first week in Prague and getting a Czech SIM card or eSIM.

Are there USB sockets and power outlets in public places?

Many cafés, hotels and trains have sockets or USB charging points, but not all. A power bank is a sensible backup on a long day out; see our guides to walking in Prague and public transport apps, because maps and ticket apps drain a phone quickly. Check whether your train has sockets before you rely on them: Check what your train or bus offers before you rely on it.

Anything to know for longer stays?

If you are moving into a rented flat, check that sockets are working and that the fuse box is accessible. Kitchen appliances in Czech flats are designed for 230 V. If you bring appliances from abroad, check their voltage. For flats with older wiring, ask your landlord about the safety of the installation.

Two more small jobs for day one: fill a bottle at the tap, which is safe to drink, and sort out cash with the ATM guide before you need it.

Frequently asked questions

What plug type does Czechia use?

Sockets are Type E, and the two-pin Type C plug fits them. Check that earthed plugs match the socket before you rely on them.

What is the voltage in Czechia?

230 V at 50 Hz, the same as most of Europe.

Can I use my US hair dryer in Prague?

Only if the label says it accepts 230 V. Many US hair dryers are 120 V only and can be damaged or become dangerous.

Do I need a converter for my laptop?

Usually not. Most laptop chargers accept 100 to 240 V, so a plug adapter is enough. Check the label.

Do UK plugs fit Czech sockets?

No. UK Type G plugs need an adapter.
