Prague’s electrical system at a glance
Czech Republic uses the standard continental European electrical system:
- Plug type: Type C and Type E (also compatible with Type F — Schuko)
- Voltage: 230V
- Frequency: 50 Hz
- Round pin size: Standard European 4.8mm pins
This is the same standard used throughout most of continental Europe (Germany, France, Austria, Italy, Spain, etc.). If you’re travelling from another EU country, your plugs will work with no adapter needed.
Country-by-country adapter situation
Visitors from the UK
UK plugs (Type G — the three-rectangular-pin system) do not fit Czech sockets. You need a UK-to-EU adapter. These are cheap, small, and available at:
- Most Czech airport arrivals shops
- Any electronics shop (Datart, Electro World) in Prague
- Convenience stores near major hotels
- Amazon / any UK retailer before departure
A basic UK-to-EU adapter costs 150–250 CZK (~€6–10) locally. Buy one before you leave — it’s smaller and you won’t have to hunt for it at the airport.
Visitors from the US, Canada, Mexico
North American plugs are Type A/B (flat parallel pins, 120V/60Hz system). Two issues:
1. The plug shape: Type A/B plugs don’t fit European Type C/E sockets. You need a universal or US-to-EU adapter.
2. The voltage: This is more important. Czech Republic runs at 230V. North America runs at 120V. Most modern consumer electronics (phone chargers, laptop power supplies, camera chargers, electric toothbrushes) are “dual voltage” — they automatically handle 100–240V. Check the label on your device or charger: if it says “100-240V ~ 50-60Hz,” you’re fine with just a plug adapter.
What is NOT dual-voltage and will be damaged: Older hair dryers, some hair straighteners, electric shavers with older motors, some kitchen appliances. Check the voltage label before plugging in without a voltage converter.
If your hair dryer says “120V only,” do not use it with an adapter in Prague. Czech hotels nearly always provide a 230V hairdryer in the bathroom — use that instead.
Visitors from Australia, New Zealand
Australian/New Zealand plugs (Type I — angled flat pins) need an adapter for Czech sockets. Same dual-voltage situation as above — check your device labels. Most modern Australian electronics are dual-voltage.
Visitors from South Africa
South African plugs (Type M — large round three-pin) and the older Type D also need an adapter. Same advice: check device voltage labels.
Visitors from Japan
Japanese plugs (Type A, 100V/50Hz or 60Hz depending on region) need an adapter for the plug shape. Voltage is also different — most modern electronics are dual-voltage (check the charger/device label). Traditional Japanese appliances designed for 100V specifically may not work correctly at 230V even if the plug fits.
What you likely don’t need to worry about
Phone chargers: Every modern USB-C and Lightning charger is 100-240V dual voltage. Check yours but it almost certainly says so on the block.
Laptop power supplies: All major laptop manufacturers (Apple, Dell, Lenovo, HP, ASUS) ship universal power supplies. Check the label — it will say 100-240V.
Camera battery chargers: Canon, Nikon, Sony, Fuji camera chargers are all dual-voltage.
Tablet chargers: Same as phones.
Electric toothbrushes: Most modern Oral-B and Philips Sonicare models are dual-voltage. The charging stand will have a label.
Sockets in hotels
Prague hotels have standard Type C/E/F sockets throughout. Higher-end hotels increasingly add USB-A and USB-C ports in bedside units — don’t count on these but they’re a bonus when present.
Important note about bathroom sockets: For safety reasons, European standard bathrooms only have a shaver socket (the small two-pin socket specifically for low-powered devices like electric razors). You cannot plug a hair dryer, phone charger, or laptop into a bathroom shaver socket — they’re low-wattage by design. Use the bedroom sockets for everything else.
Buying adapters in Prague
If you arrive without an adapter:
- Airport (both terminals): Several shops sell travel adapters. Expect airport pricing (200–350 CZK).
- Palladium Shopping Centre (Náměstí Republiky): Datart electronics store has a wide range.
- Nákupní centrum Anděl (Smíchov): Electronics stores.
- Albert or Tesco supermarkets: Often carry basic travel adapters in their seasonal travel sections.
- Amazon.cz or Mall.cz: Online delivery in 1-2 days if you’re staying long.
A universal travel adapter (handles UK, US, Australian plugs in EU sockets) costs 250–500 CZK (~€10–20) at electronics shops.
What we’d actually do
If you’re from the UK: buy a EU adapter before leaving — they cost £2–4 from Amazon and you’ll never need to think about it again. If you’re from North America: check your charger labels tonight (they almost certainly say 100-240V), buy a cheap adapter, done.
The voltage converter question trips people up, but in 2026 almost every travel-relevant electronic device is dual-voltage by default. The one thing to double-check is your hair dryer if it’s an older model or a high-wattage styling device.
Common mistakes
Plugging in a 120V-only device without a voltage converter: This will at minimum trip the circuit breaker and at worst damage the device or cause a short. The 230V Czech socket delivers twice the voltage of a US socket to a device that cannot handle it.
Confusing the bathroom shaver socket with a regular socket: The small round socket in European bathrooms is intentionally low-power. It looks similar to a regular socket but isn’t. Plugging a high-draw device in here is ineffective (it won’t charge properly) or damaging.
Forgetting adapters travel invisibly: Adapters are small and easy to leave behind in hotel sockets. Do a socket check before checkout.
Buying a “travel adapter” that’s just a mechanical plug shape conversion, not a voltage converter: This is fine for dual-voltage devices (most modern electronics). It is not fine for single-voltage devices (some older hair dryers). The adapter doesn’t change the voltage.
Questions people actually ask
Can I use a two-pin EU plug from Germany or France in Czech Republic?
Yes. Czech Republic uses the same Type C/E/F standard as continental Europe. A plug that works in Germany works in Czech Republic. No adapter needed.
Do Czech hotels have enough power sockets?
Older hotels and pensions (particularly those in converted historic buildings) often have fewer sockets than you’d like. A travel power strip lets you expand one socket into multiple. Pack a compact one if you travel with multiple devices. Note: power strips must be designed for 230V (most modern strips are; older cheap ones may not be).
Will my CPAP machine work in Czech Republic?
Most modern CPAP machines (ResMed, Philips Respironics) are dual-voltage (100-240V). Check your device’s power label or documentation to confirm. If it’s dual-voltage, you just need a plug adapter. Some models have a built-in humidifier that requires distilled water — Czech pharmacies (lékárna) sell distilled water (destilovaná voda).
What’s the easiest all-in-one adapter for a UK traveller?
A “UK to EU” adapter with a small profile — not a full universal adapter with multiple flip-out prongs, which are bulkier than necessary. Amazon UK sells decent ones from brands like Skross and CONAIR for under £5. Alternatively, a universal adapter covers you for multiple destinations in one unit.
