The machine that I own is the Z1 Auto. The Z1 Auto is powered by a lithium ion battery... which means the battery is extremely lightweight battery and provides the most power of all other batteries on the market..
I was skeptical at first when buying the battery pack... My concern was how long the battery would last So I got an extra battery to accommodate the Z! Auto if this battery gives out in the middle of night.
I ramp on 5 for 35 minutes and my pressure settings for APAP therapy is 8-16 and my doctor says that I am pretty consistent on an 13. Normally, I sleep for about nine hours so I haven't had a chance to see what the batteries full potential is, but I feel confident if I pushed the battery I could get as much as 11 hours and I haven't had to use my backup battery yet.
