Why

Compatibility is unconfirmed. Read the exact INPUT voltage range and frequency on your device or power supply, and compare them with the destination. The whole local range must be covered; 110–220V does not include 100V or 230–240V. Confirm the actual plug, grounding and manufacturer restrictions. Do not plug in while these details are unknown. Most modern CPAP machines are dual-voltage (100–240V) and need only a plug adapter — but as a medical device, never assume: confirm the exact label and check whether your heated humidifier is frequency-sensitive. Bring the manufacturer's travel power supply, consider a battery pack for flights, and avoid cheap voltage converters that output a non-pure sine wave.

Czechia runs 230⁠V / 50⁠Hz. Czechia (Czech Republic) runs 230V at 50Hz with Type E sockets that also accept the Europlug (Type C). A standard Europe adapter covers it.

Scope

ResMed: AirSense 11 user guide: The guide specifies 100-240 V, 50-60 Hz, typical/peak consumption, and Class II equipment. These values apply to AirSense 11, not every CPAP.
Philips: DreamStation BiPAP autoSV user manual: The manual specifies 100-240 VAC, 50/60 Hz and Class II equipment for this model. Exact medical-device instructions remain model-specific.

Find the INPUT label first. If the label is missing or unclear, do not plug it in and do not buy a converter on guesswork.

For medical devices, always confirm voltage on the label and check with the manufacturer when in doubt.

FAQ

Can I use my CPAP machine in Czechia?

Check your CPAP machine's label before using it in Czechia. Czechia runs 230⁠V / 50⁠Hz on Type E/C sockets.

Will a travel adapter let me use my CPAP machine in Czechia?

Not by itself. First check the label — if your CPAP machine is single-voltage, a plug adapter will not protect it from 230V.

Do I need a voltage converter for a CPAP machine in Czechia?

First check the label. If it says only 120V or only 230V and that does not match Czechia's 230V, do not buy or use a converter until wattage and local voltage are confirmed.

What plug type does Czechia use?

Czechia uses Type E/C sockets at 230⁠V / 50⁠Hz.

Adapter vs converter explained

Guidance only — not professional electrical advice. Always confirm against your device's label before plugging in. Local wiring (especially in hotels and older buildings) can vary.
