Hi,
I brought a small waterless Cpap with me on the CF this past Sept-October. It was the main reason my husband and I chose private accommodations rather than albuergues, as I was unsure about finding outlets and all the minor fussing it took to set it up. I also suffer from insomnia and really needed privacy at night, so that was another consideration.
Although the Cpap was small I opted to send it ahead each day using the various transport services as I didn’t want anything happening to it - plus the added weight and need to keep it out of harm’s way ( by that I mean my own clumsiness or rain or whatever. )
There are some good and informative threads here about using them on the Camino- I scoured them all before we left and it was among my main worries. It turned out not to be a big deal in the end and I never had a problem being able to use it. Hope you find the same!
