Extended Life Battery for Z1 and Z2 Travel CPAP Machines

Purchased this in a hurry since I had a trip to go to and I needed to bring my machine with me. I wasn't sure if it was going to be up to my expectations but after using it I really like it. Lengthy battery life and I was able to take it on the plane with me as well since its FAA compliant.

I buy this for my mother because she has the Z2 small machine. She said she like how long the battery lasts. She used for almost two nights before charging.

I wanted something small to use as a backup battery for my Z2. I looked around and found this one specifically for my Z2 so I purchased it. It arrived and I used it for almost the entire night without issue. I have to say I am pretty pleased with how long this backup battery lasts and am pleased with my purchase in general.

I needed to power my Z2 machine on a trip last year but I couldn't so my wife purchased this battery for me. I have used it a few time just to try it out and I really like it. It lasts a long time, at least for me, but that may have to do with my pressure setting. I can run my machine all night and it would still have some power when I wake up. Good battery, I would recommend.

I got this to use with my Z1 machine since I was staying somewhere that did not have a plug by the bed. The battery itself is a little heavy which is why I'm giving 4 stars but that actual duration of the battery is pretty good. My pressure level isn't too high so the battery lasts me a good while.
