Hi, I use a deep cycle AGM battery that is 12 V and 35 AH (amp hours) to power my CPAP when there is no electricity available. I use this when camping. My CPAP is medically necessary and life saving, prescribed by my doctor.
This is what the AGM battery looks like. It is similar in size to a car or marine battery:

It is spill proof and contained in a battery box to prevent short circuiting.
Can I bring it with my, along with my CPAP machine, laptop bag, and purse as a carry on for a later camping trip? And also for use on the flight if I get sleepy? (Note: the CPAP unit must be on the same level as my head; it can't be on the floor).
