M Series External Power Supply Overview
The power cord/cable is not included. If you are missing the cord that plugs into the wall socket visit this page: Power Cord for Respironics, Resmed S8 & S9, Sandman, SleepStyle, ZZZ-PAP, and IntelliPAP machines.
This is for 110v to 230v AC and cannot be used in a DC configuration. See Respironics Remstar DC Power Adapter to connect from the CPAP to a cigarette lighter adapter.
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.
We include information about the power needs and capacities on the CPAP.com pages our products. Please see the "POWER" tab on any machine product page for this information. You can also see a summary of the voltage range and whether it is DC capable on our Compare Charts.
Here is a video explaining differences in power cords and power supplies of various CPAP machines:
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 the models CPAP.com sell contain power converters that enable the machine to operate on any AC current from 100 to 240 volts without any adjustment.
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.
There are small, portable battery packs that will operate a CPAP set at 10cm for at least one night, or about eight hours. CPAP.com sells full Battery Kits that come with everything needed to run your machine off battery power including the correct cables needed for your machine and a battery. You can find the battery kit for your machine Here. On each battery kit page, you can input your machine and pressure setting to see an estimate battery life for your machine.
