Travel with your CPAP

A packing checklist, what to expect at airport security, batteries that can fly, and the plug you'll need.

Packing checklist

At the airport

Pack your CPAP in your carry-on, never in checked bags, so it can't be lost or damaged. In the US, airlines must not count it toward your carry-on limit as long as it fits in the bin or under the seat. Rules elsewhere vary, so check with your airline.

At US security, take the machine out of its case for the X-ray. The mask and tube can stay in the case. You can bring a clear plastic bag to put the machine in while it's screened. Empty the water chamber before you go.

Using it on the plane

Most airlines let you use a CPAP in flight, but ask them at least 48 hours ahead: many want to know in advance, and some ask you to run it on battery because seat power isn't guaranteed. Bring enough battery for the whole flight with some to spare, and turn off the humidifier.

Batteries and the battery calculator

1. Can my battery fly?

Look on the battery's label for watt-hours (Wh). If it only shows mAh and volts, enter them here.

2. How many nights will it last?

0.8 nights, roughly

Up to 100 Wh: allowed in your carry-on without airline approval. Never in checked bags.

The draw depends on your machine and pressure, and the heated humidifier and heated tube can use several times more. Turn them off on battery. Your battery maker's chart for your machine is the best guide; use this to compare.

Power and water abroad

Most CPAP power supplies work on 100 to 240 volts, so you only need a plug adapter, not a voltage converter. Check the label on your power brick: if it says 100-240V, you're set. Use distilled water in the chamber if you can find it; if you can't, check your machine's manual for what it allows.
