Cpap 12 volt power supply

I went 12V on mine too. I can't remember where I bought it, but it wasn't horribly expensive. At first, I made a socket with one quick disconnect male to plug into an open fuse slot in the fuse/breaker panel and a clip that I attached to a ground point. I added a 15' extension and it worked great.

I've since installed a 12V socket.

UPDATE: The website was thecpappeople.com and the cord for my Respironics CPAP was $24.50, but it doesn't have to step up the voltage like yours apparently does, which explains the higher price.

Leo If I am understanding you correctly the power supply that is currently running my machine will also power my machine when I connect it to 12 volts. Looking on the back of my power supply I do see some info regarding 24 volts? So the only thing I need is the proper cord? Dave

I do not think you have the same CPAP.. If the OP's CPAP runs on 24v, which the owners manual I looked up says it does, It won't run, or won't run properly, at 12v. Patriot Dave, Look at the power supply you have now, it should say input and output voltage. Whatever the output voltage is, (and I am pretty sure it is 24v), that's the voltage your CPAP uses.

Originally posted by Leo B Yes, we didnt have a radio shack close, so I just bought the 12v cord from the cpap company  that replaces the power cord on your machine ( plugs in the same hole) and the into the 12v plugs we added to the pod. Works great.

Outstanding!

I don't CPAP, but I do 12v..  

Your owners manual should give you the specs of the 12v input, or it may say right on the case of the CPAP. Google your model number if needed. I assure you there is nothing magical about the factory power supply, besides the price. Any power supply that puts out the proper voltage will work.

It looks, by the manual, that it's power supply provides 24v with a max use of 107 watts.. So a dc to dc converter of the proper size, and plugs to match the input for the DC input is what you would need.

This converter appears to fit the bill.. You will need to wire in a 12v plug on the input side, and the proper two pin cannon plug on the CPAP side..
