Before you go: the essentials to have with you
Keep this information with you (on your phone and printed if possible):
- Your therapeutic pressure (or the range if you use an Auto-CPAP)
- Your mask type and size + reference if available
- Your doctor or sleep clinic contact details
- Your insurance details (policy number + emergency contact)
- Your CPAP brand, model and serial number
Packing and protecting your CPAP
The basic rule: always carry your CPAP as cabin luggage, never in the hold. A medical device with fragile components should not be subjected to the bumps of the hold, and you risk losing it with your checked bags.
For packing:
- Use the original carry bag or pouch provided with the device.
- Place the tubing and mask in a soft protective bag to avoid kinks or cracks.
- Store accessories (adapter, power cable, empty water chamber) in a separate small pouch.
- Always empty the water chamber before placing the device in your bag - a full chamber can leak and damage the electronics.
Power supply abroad
Good news: the vast majority of modern CPAPs have a universal power supply (100-240 V, 50/60 Hz). This means they work in virtually every country without a voltage converter.
To check: look at the label on your CPAP's power supply (block or cable). You should see "100-240V~". If so, you only need a plug adapter - not a transformer.
Power plug adapters by country
| Region / Country | Plug type | Voltage | Adapter needed from Belgium |
|---|---|---|---|
| EU (excl. UK) | Type C / E / F (Schuko) | 230 V | No (same plug) |
| United Kingdom | Type G (3-pin) | 230 V | Yes - UK adapter |
| USA / Canada | Type A / B | 120 V | Yes - adapter + verify 100-240 V |
| Australia / New Zealand | Type I | 230 V | Yes - AU adapter |
| Japan | Type A | 100 V | Yes - adapter + verify compatibility |
| South Africa | Type M (3 large round pins) | 230 V | Yes - ZA adapter |
Water for the humidifier while travelling
Distilled or demineralised water is recommended for your CPAP humidifier. While travelling, this requires some planning.
Can you use bottled water?
Bottled mineral water is not ideal: it contains mineral salts that can leave deposits in the water chamber. If you have no other option, prefer low-mineral water (low TDS) to minimise deposits, and clean the chamber more frequently.
Tap water carries the same risks as mineral water (limescale, impurities), with an additional microbiological risk depending on the country. Avoid where possible.
Practical solutions while travelling
- Buy distilled or demineralised water at a supermarket at your destination (sold in 1 to 5 litre containers in most countries).
- Ask your hotel whether they can provide demineralised water (some hotels do upon request).
- For short stays, you can travel without the humidifier: remove the water chamber and fit the sealing cover if your model allows it. Some patients tolerate treatment without humidification perfectly well for a few nights.
Practical hotel tips
The power outlet is far from the bed
This is one of the most common issues. Solutions:
- Pack a compact power strip or short extension lead (35 to 50 cm is often enough). It lets you plug in the CPAP next to the bed even if the outlet is behind the desk.
- A longer power cable (if available for your model) can also solve the problem.
The room is too dry or too warm
- If you use a humidifier, increase the humidification level slightly.
- If you use a heated tube, adjust the temperature to prevent condensation.
You are sharing the room
- Mask noise can disturb your room companion. Masks equipped with QuietAir technology (ResMed) or nasal pillows masks are generally the most discreet.
- Make sure to fit your mask properly before sleeping to minimise leaks and exhaled air drafts.
Van, camping and off-grid
Off-grid travel with a CPAP is entirely achievable. Several power solutions exist depending on your situation.
12V / 24V power from a vehicle
Many CPAPs can operate directly on 12V or 24V with a compatible DC cable for the specific model. Check the availability of a DC power kit for your device (available separately or through the manufacturer). This is ideal for van or motorhome travel.
12V → 220V inverter
An inverter converts your auxiliary battery's 12V current into 220V AC, allowing you to plug in your CPAP normally. A practical but less energy-efficient solution than a direct DC cable.
Solar panel
For extended van or camping stays, an auxiliary battery recharged by a solar panel can power your CPAP. Autonomy depends on your pressure, whether you use the humidifier, and battery capacity.
External CPAP battery
An external CPAP battery allows you to run your device without a mains power source. It is essential for camping nights, in-flight CPAP use (if you wish to use it on board), or any situation without access to mains power.
Key considerations when choosing a CPAP battery:
- Capacity (Wh): the higher the capacity, the longer the runtime. Budget approximately 30 to 60 Wh per night without humidification, considerably more with it.
- Compatibility: some batteries are model-specific (e.g., ResMed battery for the AirMini), others are universal.
- Humidification: using the humidifier drastically reduces battery runtime. To maximise autonomy, disable the humidifier and heated tube.
- Airline rules: lithium-ion batteries above 100 Wh may be subject to cabin restrictions. See our page CPAP on flights - airline rules for details.

Do you need a travel CPAP?
You can travel perfectly well with your regular CPAP. A dedicated travel CPAP becomes interesting if you travel frequently:
- Compact format: easier to fit in a cabin bag, especially on flights with space restrictions.
- Lightweight: the ResMed AirMini weighs under 300 g - it is specifically designed for travel.
- Simplified battery compatibility: travel CPAPs often pair better with portable batteries.
If you travel fewer than 4 to 6 times a year, your regular CPAP with a good carry bag is perfectly adequate.
Altitude: will my CPAP still work?
At high altitude, atmospheric pressure decreases. Some modern CPAP devices feature automatic altitude adjustment and compensate for the pressure difference. Others need to be adjusted manually.
Practical tips:
- Check in your device manual whether altitude compensation is automatic or manual.
- Most CPAPs work correctly up to 2,500 m altitude without special adjustment.
- Above that, consult your doctor or the manufacturer's customer service.

Frequently asked questions about travelling with a CPAP
Yes. Under IATA rules, a CPAP is recognised as a medical device accepted in the cabin in addition to your standard carry-on. Carry the device in a dedicated bag, present it in a separate tray at security (like a laptop), and keep any battery in the cabin. A medical letter from your sleep physician helps at stricter checkpoints. See also our detailed CPAP on a plane page.
On most European and North American airlines, yes: the CPAP is a recognised medical device and is not counted against the standard allowance. Ryanair, Brussels Airlines, Lufthansa, Air France, TUI and KLM apply this rule, generally on presentation of documentation. Still, check your airline's policy at least 48 hours before departure. Some Asian carriers require advance declaration at booking.
Modern CPAPs (AirSense 11, AirMini, DreamStation 2, Prisma Smart) all accept universal 100-240 V input. You only need a plug adapter for the country: type A/B (US, Canada), type G (UK, Ireland, HK, Malta), type I (Australia), type C/F (continental Europe). A universal travel adapter for 15-25 euros covers everything. No voltage transformer needed: only the physical plug shape changes.
Always pack a 3-to-5-metre compact extension cord with your travel CPAP. It is the most forgotten accessory and the most common reason for a CPAP-less night in a hotel. If the bathroom or a wall away from the bed is the only option, run the cord along the floor and secure it to avoid trips. If no power is reachable, a compatible external battery covers you for one or two nights.
Distilled water remains the official recommendation to preserve tank life and avoid mineral build-up. While travelling, if tap water is potable and low in minerals, it is acceptable occasionally (a few nights). In hard-water regions (Mediterranean, North Africa, South-East Asia), prefer low-mineral bottled water. For long stays, buy distilled water locally (pharmacies, supermarkets) or use HumidX passive humidification if you have an AirMini.
A Medistrom Pilot 24 (97 Wh) typically covers one full night with humidifier off, or two nights on AirMini with HumidX. A 200 Wh battery such as EcoFlow or Jackery can cover three to four nights depending on pressure. Consumption depends heavily on therapy pressure, heated tube and humidifier. For camping or trekking, disable heated humidification: it is by far the biggest consumer. See our CPAP battery guide.
Generally no: the CPAP is a personal medical device with no customs declaration required in the Schengen area, the EU, the US, Canada, the UK and most countries. If you travel with a brand-new device still boxed or with multiple units (rare), keep the invoice to avoid confusion with a commercial import. A multi-language medical letter helps in stricter jurisdictions (Russia, mainland China, Middle East).
Yes. With altitude, atmospheric pressure drops: to maintain the same relative therapeutic pressure, your CPAP must adjust its motor. Modern ResMed (AirSense, AirMini), Philips (DreamStation 2) and Loewenstein machines include automatic altitude compensation up to roughly 2500 to 3000 metres. Beyond that (Cusco, La Paz, Himalayan lodges), consult your physician before leaving: central apnoea can worsen at high altitude and may require specific follow-up.
It depends on frequency and type of trip. For a few trips per year, a standard AirSense 11 travels perfectly (1 kg, carry case, universal voltage). For frequent travel, camping, trekking or regular flying, a dedicated travel CPAP like the ResMed AirMini (300 g, HumidX) is a justified second-device investment. See our ResMed AirMini guide.
