USA to Czech Republic Plug Adapters
Best choice
Our Adapter Recommendation
A US to type C/E plug adapter is all that you will need for a trip to the Czech Republic.
A simple ungrounded adapter is compact and enough for phone chargers and most travel electronics. Models with USB or USB-C ports are useful when charging several devices, while PD ports are suitable for compatible laptops. For grounded equipment or several mains-powered appliances, choose a grounded adapter or power strip.
Our recommendations for the best US to Czech Republic travel adapters ensure that you'll always be able to connect your American type A/B plugs to the Czech type E outlets.
Choosing the Right Power Adapter
Having overcome the pesky differences in plug types and outlet configurations you now need to decide what sort of adapter suits your own, specific needs.
If you decide to buy an adapter, here are some useful features to consider:
- Grounded vs ungrounded adapters
- Multiplug adapters
- Extensions / power strip adapters (great for families)
- Integral USB / USB-C ports for charging devices like phones and tablets
- Dedicated charging hubs with multiple ports
- USB-C port with power delivery (PD) using GaN technology for laptop charging up to 140W
- Universal adapters (any plug to any outlet) for the ultimate in versatility
- Combined transformer / adapters
Czech Republic Electrical Supply
The Czech Republic uses plug types C and E and outlet type E.
The electrical supply voltage is 230 V and the frequency is 50 Hz.
Czech Republic - Traveler Notes
Type E sockets are standard, earthed appliances ship with an E+F plug. Type C Plugs are common, especially for low-power devices. Type C wall sockets (actually E without the grounded pin and with narrower holes) are very uncommon, and exist only in very old installations.
Voltage Converters
Please be aware that whilst a power adapter will allow you to physically insert a US plug into a Czech outlet it will not change the voltage or frequency of the local mains supply.
Voltage - The Czech mains supply is 230 V which is well above the normal US range of 120 V +/- 5%. Single-voltage US appliances designed for 120 V will need a transformer or voltage converter to operate safely. If it is not marked as able to accept the local voltage do not plug it in! It is extremely dangerous to attempt to operate appliances at voltages that are higher than they are rated for and it could result in damage to the appliance, fire and serious injury to the operator
Frequency - The Czech Republic operates at 50 Hz, compared with 60 Hz in the US. Most modern travel electronics are designed to work at either frequency and will be marked 50/60 Hz. However, some appliances containing motors, clocks and other frequency-sensitive equipment may not operate correctly at 50 Hz. Check the frequency rating on your device before use; if it is marked 50/60 Hz, it is suitable for either frequency. If you are unsure, particularly with specialist or medical equipment, check with the manufacturer.
Most modern travel gadgets, chargers and laptops are dual voltage and will work worldwide; check the appliance or power supply for an input such as 100-240 V, 50/60 Hz.
If you have equipment that is not compatible with the Czech supply voltage, check our transformers page for further information and available options for transformers and power converters that you can use in the Czech Republic. Voltage converters and transformers only change the voltage, not the frequency, of the supply. Changing the frequency requires specialist frequency-conversion equipment, which is not normally practical for travelers.
If you need to take items like hair dryers / straighteners that draw high current then see our hair straighteners page for information on how it can affect your choice of travel adapter.
Czech Republic Plug Type Specifications
Plug Type C
Plug type C (CEE 7/16) is the most widely used electrical plug in the world but most common in Europe. It has 2, insulated, 4mm round pins spaced 19mm apart and 19mm long. The spacing of the pins tapers to 17.5mm at the tips assisting in gripping the outlet.
A second version (CEE 7/17) has 2, uninsulated, 4.8mm pins and is rated at either 10A or 16A for high power, ungrounded appliances.
Type C outlets are being phased out in most countries around the world and are being replaced with their grounded equivalents (Types E and F in Europe).
Plug Type E
Plug type E (CEE 7/6) is mostly used in France, Belgium, Poland, Slovakia, the Czech Republic, Tunisia and Morocco and rated at 16A. It has 2, 4.8mm round pins spaced 19mm apart and 19mm long. The outlet has a 4.8mm male grounding pin that is 14mm long and offset by 10mm from the other 2 pins. The plug has a corresponding hole to accept the grounding pin and is polarized.
The outlet is recessed by 15mm to prevent electrocution risk in the event of a partially pulled out plug.

About Travel Adapters for the Czech Republic
-
The Czech Republic uses type C and E plugs, which are ungrounded and grounded variants.
-
The Czech Republic uses type E outlets.
-
American travelers will need a USA (type A/B) to type C/E plug adapter for the Czech Republic. Adapters with USB or USB-C ports are useful for directly charging compatible devices. Some US appliances may also require a voltage converter.
-
The mains supply in the Czech Republic is 230 V which is well above the normal US range of 120 V +/- 5%. Many travel gadgets are dual voltage and will work worldwide; check the appliance or power supply for an input such as 100-240 V, 50/60 Hz. Single voltage US appliances designed for 120 V will need a voltage converter or transformer to operate safely. Do not plug a 120 V-only appliance into a 230 V supply - it is dangerous.
-
To charge your phone in the Czech Republic you can use your normal phone charger with a type C/E plug adapter. Modern phone chargers are normally dual voltage, but check the input rating before use.
Alternatively, you can use a travel adapter with built-in USB or USB-C ports and connect your phone directly with the appropriate charging cable. The adapter's USB ports convert the local supply to the voltage required by your phone, so no separate voltage converter is needed. -
Yes, type C plugs are fully compatible with the type C/E outlets used in Czech Republic.
