Taking Your CPAP on a Cruise: Cords, Distilled Water and Power by Cruise Line

Yes, you can take your CPAP on a cruise. The major lines all make room for it. What decides whether your first night at sea goes smoothly is three things you handle before you sail: whether your line lets you bring your own extension cord (several don't), how you'll get distilled water, and whether you've told the line about your machine and any battery you're bringing. On most lines that means a special-needs or medical form, often due 30 days before sailing. Then carry the CPAP on board yourself and check where the outlet is the moment you walk into your cabin.

Here's how the big lines handle it, and where a portable CPAP battery fits in.

CPAP rules by cruise line

Cruise lines word these policies differently and update them often, so treat this as a starting point and confirm with your line before you sail.

Extension cords and power strips

This is the rule that catches the most CPAP users, because what's fine on one ship gets confiscated on another.

Lines that don't want your cord: Royal Caribbean prohibits extension cords, power strips and multi-plug outlets, but lists an extension cord among the accessible equipment you can request with 30 days' notice. Celebrity also puts extension cords on its prohibited list and asks you to request one at least 30 days out. MSC tells guests not to bring their own and hands out complimentary cords on board.

Lines that allow a cord without surge protection: Carnival and Holland America allow power strips and extension cords that are not surge-protected. Norwegian goes further and suggests bringing a cord about 6 feet long without a surge protector, and warns that unsafe cords may be confiscated at screening. Princess allows cords with or without surge protectors but inspects them, and holds anything it considers hazardous until you disembark.

If your line provides a cord, request it when you file your paperwork rather than hoping one is free on embarkation day. If your line allows your own, pack one that clearly has no surge protection so it doesn't get pulled at the security check.

Cabin outlets: what to expect

Princess, Holland America, Celebrity and Norwegian list both 110V and 220V outlets in staterooms. MSC lists 120V and 240V. Check the input range printed on your CPAP's power supply before you go so you know which outlet it can use.

The bigger question is where the outlet is. Depending on the ship and cabin, it may not be near the bed. Look as soon as you board, and if your hose won't reach comfortably, ask your stateroom attendant or Guest Services what they can do.

One more detail on Holland America: stateroom power runs through the keycard slot, so pulling the card can cut the outlets. Guest Services can override that for medical reasons. Ask on day one.

Distilled water on a cruise ship

Most lines will supply distilled water, but how you get it varies.

• Royal Caribbean and Celebrity: request it with your 30-day notice.
• Norwegian: pre-request it at least 4 days before sailing (877-474-2983).
• Princess: ask when you make your reservation.
• Carnival: buy it before the cruise or on board. If you bring your own, carry it on with the CPAP.
• Holland America: order it, for a fee, under Manage My Cruise > Beverage Packages. Your own is allowed if it isn't in plastic bottles, up to six liters.
• MSC: complimentary. Request it at booking.

If your line charges, or you'd rather not count on it, ask your sleep or equipment provider whether a heat and moisture exchanger is an option for you on the trip. We explain how a CPAP HME works, but whether it suits your therapy is your provider's call.

The special-needs form: what to put on it

Royal Caribbean asks CPAP and BiPAP users for the machine's dimensions, weight and battery type, submitted at booking and no later than 30 days before sailing (special_needs@rccl.com, 866-592-7225). Carnival has a dedicated Oxygen, Concentrator & CPAP Machine Form through access@carnival.com. MSC wants its Accessibility & Medical form at least 30 days out, and Disney asks for its special services form on the same timeline. Princess doesn't require notice for a CPAP, though it still wants your water request at reservation.

List your CPAP battery on the form too. Rather than guess how a line treats a CPAP battery, tell it what you're bringing. Two lines have battery language worth clarifying. Norwegian's prohibited list includes "large batteries" without defining the term. Carnival requires power banks and portable chargers to come aboard in carry-on luggage and says they must not be left unattended while charging in staterooms. Put the battery's make, model and watt-hour rating next to the CPAP on the form, and get the line's answer in writing before you sail.

Embarkation day: keep the CPAP with you

Carnival requires CPAP machines to be carried on as carry-on luggage, and Princess says to bring yours in hand luggage. That's good practice on any line. Don't hand your CPAP or its battery to a porter with your checked bags, which can take hours to reach your cabin.

Bring every supply you need for the whole trip, plus spares. Princess notes that CPAP supplies aren't available on board, and that's a safe assumption anywhere at sea: mask cushions, filters, tubing and the power supply all come from home.

Where an EXP48PRO APEX battery helps on a cruise

A cabin has an outlet, so why bring a battery? Because the outlet isn't always where you need it, and some lines won't let you fix that with your own cord.

Power at the bedside without a cord. The EXP48PRO APEX sits on the nightstand and powers your CPAP directly through its DC cord. There's no extension cord across the cabin floor and no power strip for security to question. If the outlet is across the room, charge the battery at the desk during the day and move it to the bedside at night. Runtime is an estimated 2–3 nights with the humidifier and heated hose off, so a daytime charge keeps it ready for the night. Our runtime calculator gives an estimate for your machine and settings.

A backup if cabin power drops. If the outlet is close enough, plug the battery's charger into it and your CPAP into the battery. The CPAP runs off the battery the whole time while the charger tops it up, so if the outlet loses power, from a keycard slot or anything else, nothing switches over. Your CPAP was already running on the battery and keeps going. It works as a UPS with a 0 ms transfer time, and it's fine to run it this way every night. Princess's own guidance is that medical devices needing power should have fully charged batteries or a backup that doesn't need electricity.

The nights around the cruise. A pre-cruise hotel, a long port day, a tender back to the ship, a delayed flight home. The same battery covers all of it.

Flying to the port. The EXP48PRO APEX is 153.6 Wh, under the FAA's published 160 Wh carry-on threshold. Final acceptance rests with TSA and your airline, so check with your carrier. It travels in your carry-on, never in checked baggage. Our guide to flying with the EXP48PRO APEX covers the airline side, and here's what to do if your battery is questioned at the airport.

Driving to the port. If you're sailing from a port you can drive to, the EXP96PRO APEX is an option: 307.2 Wh and two DC ports, so two CPAP users can share one battery. It cannot fly. Only consider it if the whole trip is by car and ship.

Set it up before you leave home

• Get the DC cord made for your CPAP model. The cord is matched to the CPAP, not the battery.
• Set the battery's output voltage to match your CPAP. The LCD shows the current output voltage.
• Turn off the humidifier and heated hose when running on the battery alone for the longest runtime. Here's how to turn them off on your machine.
• Sleep one night at home on the battery before the trip. If the CPAP won't start, this troubleshooting guide covers the usual causes.

Keep the battery dry and out of the sun

Salt air is part of the fun. Salt water on a battery isn't. Keep the battery inside the cabin on the nightstand or desk, not on the balcony, and away from anything that could spill on it. Don't leave it running in direct sunlight for long stretches, including on a sunny windowsill or a deck chair on a port day.
