I have used a CPAP in travels all over the world. I own a humidifier but don't ever use it. My machine works on either 110V or 240V and converts it to DC voltage. The placement is not critical to the operation and I often just stick it in a drawer on my side of the bed. Wash your mask and hose regularly with a bit of anti-bacterial soap. rinse well and dry during the day while you don't need it. Sleep better and travel more. Airlines allow you to bring it along as an extra carry-on. You will live longer and enjoy camping more.
