Connecting a CPAP machine to a battery?
I have been prescribed a CPAP machine for Obstructive Sleep Apnea. How do I run this while traveling if I don't have a generator or battery? I am thinking of buying a portable jump starter like thi...

First, please edit your photo sizes - my 2 monitors just about display your pics! :)
Second, That's the least efficient way to connect your CPAP to a battery. To go from DC to AC and back to DC again - (assuming your CPAP, like nearly all I've had or are familiar with - has the AC to DC brick in the power supply cord, and run off of 12VDC) induces a lot of loss.
CPAP supply companies have portable batteries available specifically for their matching machines, and of course, you pay 2-10x premium for the "name brand" matching.
My most recent CPAP (ResMed) runs off of 24VDC so I'll end up buying the 12 to 24V DC step up transformer and run off a jump start battery pack.
My prior CPAP all used 12VDC, so I made a 12V adapter to plug into a jump start battery pack similar to what you show, but mine had the cigarette lighter socket built into it.
So, a little research on your specific CPAP to see what the input voltage requirements are and you "should" be good without the converter.
Good luck!
