This product works ONLY with M Series CPAP and BiPAP machines.
It is NOT compatible with PR System One 60 Series Machines or PR System One Machines. Each of those systems have specific power adapters.
All CPAPs will operate on DC power with the use of an Inverter to change the current from DC to AC before it reaches the machine. However, many will operate on DC power without the need for an inverter, just a power cord that plugs into the CPAP and ends in a cigarette lighter plug.
Inverters do require a lot of power. If you need to use an inverter to run your machine on battery power, the inverter will probably take about half the life off the battery.
To determine if your CPAP will operate without an inverter, look for a DC outlet on the machine, either at the back or on the side, with a single opening directly in the center. It should be labeled "DC POWER" or similar term. You can also review our Compare Charts to see if your machine has a optional DC cable option.
Here is a video describing different DC cable and battery options for various machines:
All machines can connect to DC power. Some machines are configured to operate on DC Power and have a DC power outlet. Other machines require AC power and will need an Inverter that turns DC power to AC power.
Having the proper equipment is the biggest key to successfully operating the machine from a battery. For example, if your machine does have a DC outlet and you want to run your machine from a marine battery, be sure to get the correct DC cable for the machine, as well as an adapter cable with alligator clips that fits over the cigarette lighter plug.
CPAP.com sells complete battery kits with everything you need for many machines including the correct cables for those machines and batteries. If you have questions about the specific power needs of your machine, review the 'Power' tab found on the machine's product page, or give us a call at 1-800-356-5221.
Great service and product was exactly what I needed
These are direct replacement parts at a fair price. Shipping is fast and I always receive mine within a few days of ordering with the free ground shipping.
The service was great. My item arrived exactly when expected.
This power supply is the same as my original and performs well.
Works great. I have been without my apnea machine for two months due to a bad power supply. I works great. Thank you
This product works great. I took it overseas and had no issues and it worked fine.
The product works great! Delivered very quickly.
It's exactly what I've been looking for. Is the actual product that came with the unit when I first received it. Thanks, I will be doing more business soon.
Very pleased with product. Will be ordering more.
It is working as the original
The replacement power supply appears to function as well as the original. No problems so far.
I have bought it in substitution for the one that came with the machine. It's just perfect, original product.
