Phillips Respironics 450p and 550p - eehutch - 02-08-2016
Have had 2 of these, the 450 failed then dropped the 550 and it failed a few days later too. So I am into 2 weeks without a CPAP and I am really sleeping poorly. So I am a technical guy, and I start thinking I can swap parts etc and get a good unit and start taking them apart. Put one back together and zippo, no soap.
Then I start wondering about the power supply. Son of a gun, I plug in the car battery setup I have for our cabin in the mountains, and all of a sudden, I have 2 functional CPAP machines, I am in the money!!! Sleep tonight.
Must have carried over the power supply to the second unit and ...
So, I always thought the power supply was hokey, some dam thing that they had to buy a medical device grade thats not as good as a usual laptop item that will last forever.
So, all I have to do is find the other supply or make a new one. By the way, its a 12 volt input to a standard barrel connector. Easy...

Hi eehutch,
WELCOME! to the forum.!
It’s good to hear that you got both of your machines working.
Much success to you as you continue your CPAP therapy, sleep well.

Philips Respironics power supplies for the System One machines are all interchangeable 12-volt 5 amp supplies. They are really inexpensive, and you can find them through the online DME suppliers, or for that matter a standard 5-amp power supply from Batteries+ or similar electronic vendors.
