    Important Tips

    The 300 Watt DC to AC Power Inverter has an internal fan which uses a sensor to detect when it should turn on and off. The fan on this inverter will cut on and off as needed to maintain the desired temperature of the inverter.

    The use of any inverter will reduce the battery life up to 50% because the inverter, itself, uses battery power. Other components like the humidifier will further reduce the run-time.

    This inverter will not operate from a 6 volt battery.

    CPAP Video & FAQ

    Frequently Asked Questions (FAQs)

    What type of power does my CPAP need?
    Most CPAP and BiLevel machines today are designed to operate on both AC and DC battery currents. In the United States, the AC current from a wall outlet is 110 volts. Overseas, the AC current is usually 220 or 240 volt. Most batteries produce 12 volt DC current.

    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:

    Will my CPAP operate on DC / battery power?
    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:

    Will my CPAP operate overseas?
    An adapter may be required to plug a US power cord into a wall outlet in a foreign country. CPAP.com sells an assortment pack of World Traveler Power Adapter Plugs, which allow CPAP machines to plug into different types of wall sockets found in different countries.
    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.
    How do I use a battery to operate my CPAP?
    First you need to determine if your machine is configured to operate on DC power and has a DC power outlet. If your machine does have a DC power outlet and you want to run your marine battery, then you will need the correct DC cable for your machine and an adapter cable that fits over the cigarette lighter plug and ends in alligator clips.

    CPAP.com sells complete battery kits with everything you need for your machine including the right cables for your machine and the battery. You can find the right battery kit for your machine here.

    If your machine does not have a DC power outlet, then you will also need an inverter to be able to run your machine on battery power.

    If you have questions about the specific power needs of your machine, review the "Power" tab on your machine's product page, or give us a call at 1-800-356-5221.
    What type of battery should I use?
    For longer battery use, we suggest a deep-cycle marine battery. A CPAP set at 10cm will usually run for about three nights before having to recharge a deep cycle marine battery. A car battery will usually run a machine for 8 hours and still start the car.

    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 right 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.
    How do I prepare for power outages with CPAP?
    There are a lot of back up battery choices out there that can give you peace of mind in case of a power outage. The Transcend Travel CPAP Machine has Battery Options available for that can set up as a fail-over, back up battery. Review the "Power" Tab on the machine page.

    CPAP.com sells battery packs to accompany your machine if an integrated battery is not available. Visit CPAPtalk for more advice specific to your needs, or view this past thread on the topic here.
