Travel Guides
The Czech Republic uses Type C and Type E plugs with 230V electricity at 50Hz. If you're coming from the US, UK, or Australia, you'll need a plug adapter. US and Canadian travelers may also need a voltage converter for certain devices.
Arriving at Václav Havel Airport with a dead phone and a US charger that wouldn't fit anywhere taught me an important lesson: Czech outlets are nothing like back home. The country uses Type C and Type E plugs with two round pins, so without the right adapter, your devices are useless.
Here's everything you need to know about the Czech Republic's electrical system, which adapters to buy, and whether you'll need a voltage converter.
The Czech Republic uses Type C and Type E plugs. Both have two round pins, but there's an important difference between them that affects grounding and safety.
Type C plugs have two round pins that are 4mm in diameter and spaced 19mm apart. These plugs are ungrounded, meaning they don't have an earth connection. You'll find Type C on smaller devices like phone chargers, laptop adapters, and electric toothbrushes.
Type C works throughout the Czech Republic because it fits into Type E sockets. This is the same plug used across most of Europe, so if you've traveled to Germany, France, or Spain before, you've already used this plug type.

Type E plugs also have two round pins, but they include a hole that accepts a grounding pin from the socket. This makes them safer for higher-power devices like hair dryers and larger appliances. Type E is the primary standard in the Czech Republic, and it's the same system used in France, Belgium, Poland, and Slovakia.
The good news: Type E sockets accept both Type C and Type E plugs, and they're also compatible with Type F plugs (common in Germany). So if you're coming from continental Europe with any of these plug types, you're already covered.
Getting the right adapter before you fly saves hassle. Airport shops charge ridiculous markups, and while you can find adapters in Prague's electronics shops, hunting them down eats into your travel time.
Here are the best options to buy online:
The EPICKA is one of the most popular travel adapters and works in over 200 countries. It includes four USB ports plus an AC socket, so you can charge multiple devices at once. For the Czech Republic, it covers both Type C and Type E outlets.
The retractable pins mean it won't poke holes in your bag. Compact, reliable, and widely reviewed.
The TESSAN features 65W GaN-powered charging with multiple USB-C and USB-A ports. It's ideal if you need to charge power-hungry devices like laptops alongside your phone and camera.
TESSAN adapters cover 150+ countries and include safety features like temperature control and overload protection. The European version covers Type C and Type E, making it perfect for the Czech Republic.
Ceptics adapters come with Quick Charge 3.0 USB ports and often include a travel pouch. They sell country-specific adapters that are lighter and cheaper than universal ones. For the Czech Republic, look for their "Europe Adapter" which handles Type C and E outlets. Solid middle-ground option.
If you just need something simple, Amazon Basics makes a straightforward European plug adapter. No USB ports, no fancy features, just a basic plug converter. Lightweight and cheap enough to throw a spare in your bag.
The Czech Republic runs on 230V at 50Hz. Whether you need a voltage converter depends entirely on where you're traveling from:
Coming from the US or Canada?
Your country uses 120V. That's a significant voltage difference. However, most modern electronics (smartphones, laptops, tablets, cameras) are dual voltage (100-240V) and don't need a converter. Check your charger's label. If it says "INPUT: 100-240V," you're fine with just an adapter.
But single-voltage devices like older hair dryers, curling irons, or some electric shavers rated only for 120V will be damaged if plugged into the Czech Republic's 230V outlets. Either buy a voltage converter or leave those devices at home and buy travel-sized versions locally.
Coming from the UK, Europe, or Australia?
Your countries use 220-240V, which is compatible with the Czech Republic's 230V. You don't need a voltage converter, just a plug adapter (UK travelers use Type G, which is different from the Czech Republic's Type C/E).
There are four main ways to get internet access in the Czech Republic:
The Czech Republic isn't alone in using Type C and E plugs. There are actually 15 different plug types used globally, labeled A through O. Here's where the major plug types are used:
| Plug type | Countries |
| Type A & B | United States, Canada, Mexico, Japan |
| Type C | Most of Europe, South America, Asia (including South Korea) |
| Type D | India, Nepal, some African countries |
| Type E | France, Belgium, Poland |
| Type F | Germany, Netherlands, South Korea, Austria |
| Type G | United Kingdom, Ireland, Singapore, Malaysia |
| Type H | Palestine, Israel |
| Type I | Australia, New Zealand, China, Argentina |
| Type J | Switzerland, Liechtenstein |
| Type K | Denmark, Greenland |
| Type L | Italy, Chile |
| Type M | South Africa, Lesotho |
The Czech Republic shares its plug types with France, Belgium, Poland, and Slovakia. If you're planning a trip that includes both Prague and Paris, one adapter covers both.

No. The US uses Type A and Type B plugs with flat prongs, while the Czech Republic uses Type C and Type E with round pins. You'll need a plug adapter to charge your devices in the Czech Republic.
No. The UK uses Type G plugs with three rectangular pins. The Czech Republic uses Type C and Type E with two round pins. British travelers need an adapter, but not a voltage converter since both countries use similar voltage (220-240V).
No. Canada uses the same plugs as the US (Type A and B), which are incompatible with the Czech Republic's Type C and E outlets. Canadian travelers need both an adapter and should check if their devices are dual-voltage.
The Czech Republic uses 230V at 50Hz. This is compatible with most European and Australian devices (220-240V) but different from the US/Canada (120V). Most modern chargers are dual-voltage and work fine, but single-voltage appliances need a converter.
Yes. Apple chargers are dual-voltage (100-240V) and work anywhere in the world. You just need a plug adapter to fit the Czech Republic's Type C or Type E outlets.
Adapters are available at Václav Havel Airport convenience stores, electronics shops like Datart and Alza, and shopping centers throughout Prague. However, prices are higher than buying online before your trip. Amazon has adapters starting around $10.
