[CPAP] Transcend CPAP machine

[bayrunner]

The Respironics machine runs on straight 12 volt power and is very efficient with startup power at about 2.5 amps and operating power less than 0.8 amps. It will use any 12 volt source, including deep cycle lead-acid, and very compact Li-ion batteries that can be recharged from solar or automotive alternators. There are a number of threads from people that use PRS1 machines on sail boats circumnavigating the globe, campers and RV users. For a permanent machine that can be taken off the grid, it's hard to beat.

I'd suggest narrowing your search, eliminating Resmed which operates on 24 volt power and has an integrated humidifier and wireless modem, and focusing on the PRS1 and Transcend units, and seeing what can be worked out. I can point you to some threads that discuss battery use of the PRS1 units, including the use of the Poweradd Pilot Pro 32000mAh Multi-Voltage (5V 9V 12V 16V 19V 20V) Li-Ion Backup Power Bank to run units up to 3-days without recharging and without any converter or adapter other than what is included (See Amazon). These batteries are not without some issues, but they are an example of what can work remarkably well as an alternative to expensive batteries sold specifically for powering a CPAP.

Thanks Sleeprider for that information. You certainly have me thinking.
I have found the DS560HS on the internet, I assume it is similar to what you use.
Would love to have a look at any links you can point me to.
Can I program this machine myself?
I also assume you use Sleepyhead software.
Looking forward to your reply.

The 560 is the Auto version. I have one, and the DS760 BiPAP. They can both share the same humidifier unit. Both machines can be set by the user and the clinician-manuals are available from ApneaBoard CPAP Setup Manuals link. Both are 12 volt and simple to run off batteries. I use mine camping with a motorcycle and use the PowerAdd battery with a simple DC laptop charger unit to keep the battery up. It takes only two hours to charge the battery off the bike.

Giving you a specific link is a problem since this site edits out the forum I'm going to direct you to as "commercial". Put in a Google search for "Poweradd, CPAP". Read everything you get in the first two non-sponsored returns. [link to DME-owned website removed per Apnea Board rules]

Since size is not the issue, I agree with Sleeprider that the PRS1 might be the right fit. I sometimes take my PRS1 camping and I can get 3 nights (humidifier off) with a 22 ah battery. Since it's native power is 12 Vdc, it gives you greater options when it comes to power. On the other hand the Transcend requires a 14.4 Vdc Li-ion battery pack.

Sounds like the Respironics DS560HS is the way to go.
Can anyone tell me where to get the Clinician Manual - I live a long way from any provider and will have to adjust the pressures myself if the Doctor says to. I have the Clinician manual for the Resmed and had to use it (on Doctors orders) during my trial as I was too far from the Doctor for him to do it.
