Thank you so much. A follow-up question if I may. I keep reading 12V (and I saw on the resmed chart). But on the CPAP "storage and travel..." sticker it reads DC24V and 3.75A . I'm pretty much stupid with tech tech stuff. The 12V cable is ok to use? I apologizes if my question makes no sense. I'm no...

Having problems finding a back-up power for my CPAP since my pressure is so high. 5 or 6 hours would be acceptable. Medistrom failed me (last 1 hour). MaxOak K5 maybe ok but hard to tell (well for me anyway). Hoping someone can help. I am open to suggestions.

Thank you.
