RE: Backup power options for CPAP machines
After using my Medistrom dual battery configuration for over a year, I thought I would provide an update on my experience.  I have yet to have a power outage and therefore have not had to rely on the batteries as backup power.  However, I did perform a test to determine if these would work under maximum current draw.  I connected my ResMed S9 VPAP Adapt as I normally would but without the mask attached.  I then unplugged the S9 power supply from the wall.  The CPAP continued to run as if nothing happened.  About an hour later, the secondary battery was completely drained.  About an hour after that, the primary battery was completely drained and the alarm sounded.
  
Again, I would like to point out that this is a worst-case scenario.  I highly doubt anyone would be continuously using maximum CPAP pressure.  Since the VPAP Adapt is designed to adjust pressure as needed, my earlier post speculating about five hours of backup usage for my situation seems reasonable.
  
Also, it is worth pointing out that Medistrom has discontinued its Pilot-24 Plus battery (and Co-Pilot).  It now sells what it calls Pilot-24 Lite (also indicated in other threads).  It is lighter than its predecessor, has slightly less power and does not yet have a Co-Pilot equivalent.  In other words, you can use one and only one battery at a time.
  
As of this writing, there were still new Pilot-24 Plus batteries for sale on eBay.

RE: Backup power options for CPAP machines
Well, since we're updating,
I built my rig (from page 3) around a year ago as well.  
A PWRGATE PG40S mounted on a Minn Kota Trolling Motor power center (batt box with 2 12v cig lighter outputs).  Power supply to the PS input, deep cycle battery to the BATT, and the output to the cig lighter plugs on top of the box, where the Dreamstations plug in with OEM 12v cords.
We have 2 Dreamstations running on it nightly.  There have been a few brief outages and, happily, there is zero noticeable lag in switchover, so we don't wake up. 
More importantly, we had a significant outage a month or so ago.  Power was out for 2 full nights.  This rig powered both units for both nights, humidifiers and all, with no complaints.

My wife thinks I'm a danged genius, lol...

Resmed Airsence 10 Elite, slim line tubing, pressure 16, Humidifier at 4

 Just thought on a cheaper Battery back-up for home or camping use

 Looking at the spec. sheet of Resmed electrical  draw (16 pressure, 40AH, 3.33 amps )

This battery should be go for 90 hrs is this correct

Thank You
Mike

RE: Backup power options for CPAP machines
In my situation, living in the Sierra mtns @ 4K ft, I'm in need of a backup solution other than the generator - which I have but would normally turn off before going to sleep. (a generator running solely for a CPAP seems overkill.) Our power outages can be days long, but mostly are ~ 2 or 3 days.  (Almost 3 wks down in the El Nino year 1997.) I could recharge the battery backup for the APAP - using the generator during the day. I have a DreamStatiom APAP.

RE: Backup power options for CPAP machines
I am wondering if my calculations are right, does anyone have a electrical back ground
you have the 2 attachments and the thumbnail
and what draw the AirSense 10 has

Thanks
Mike

There is no way that booster pack has a capacity of 300 ah it just has the ability to provide upto 300 Amps for a short period of time. I would be very surprised if the battery in there is rated at 10 to 12 amp hrs, but with the specifications you posted it does just not provide sufficient information


If you look at the size and weight of a large leisure battery that has the capacity of 120 amp hrs you can see how your calculations are flawed sorry as to have 300ah it would need to be 3x the size and weight

Thank You Jaswilliams

  I looked at it more closely and the table supplied, and its J312B ---  7 aH, so if lucky maybe last 2 hrs.
So looking at the picture, model Number JUS500B is rated 19 AH  and my air sense 10 is 3.3 aH
so it should just a little over 5.7 hours if prefect conditions, if not  maybe 4.5- 5 hrs

Thanks again for you reply
