Connect Medistrom Pilot 12 Plus to Airsense 11 and Airmini?

[ICS55]

Hi,

I got this battery several years ago, and just replaced my Dreamstation with an AirSense11.  I also have an Air Mini.   Can any one suggest a cable or cables to allow me to connect the battery to the devices?

Thanks!

I don't have  an Airsense 11 nor a Pilot 12 (but I have an Airmini) so take everything with a grain of salt.  

WARNING:  Electrical hackery ahead, don't attempt if you don't know what you are doing. 

I don't think what you want to do requires just a cable, because you need 24V both for the airmini and for the a11 and AFAIK pilot 12 outputs 12V, same as  a car cigarette lighter plug.  You need  a voltage converter.   Resmed actually makes one.  Look for "DC Converter 65W for AirMini™ Auto CPAP Machine" that connects an airmini or airsense 11 to a car lighter plug.  (Maybe $90).  Of course you can get a no name same thing for less than half the price on Amazon.   Might work, might not, check with a voltmeter.   I'd buy the resmed one -- overpriced but UL certified, etc. 

Either way, You still need to jigger something or find a cable that connects a barrel jack  (for the Pilot 12 output, check if the inner pin is 2.1 or 2.5mm) to a lighter plug.  (I'd just cut the resmed cable and solder a good barrel jack, from eg Digikey, but probably you can find a ready-made one).   Make sure the whole shebang can do  65W or so without heating.  I am deliberate vague here, because if all this is   greek to  you, and you do not own a voltmeter you  should probably not attempt it :-) although it is a pity to throw out a working battery.  

YOU HAVE BEEN WARNED

Thanks so much for the detailed reply. I am certainly not competent to put that together ??. 

After I posted this, I realized the voltage difference. I’ll likely just get a new battery. 

Thanks again
