    Vehicle Safety Tips

    These vehicle safety tips are written according to statements from the manufacturer.

    • When the device is not in use, the Shielded DC Cord should not be plugged into the vehicle.
    • When DC power is being drawn from a vehicle battery, the manufacturer suggests only using when the vehicle's engine is turned off. Please observe battery capacity to avoid draining the vehicle's battery.
    • The alternator, which runs when the vehicle is in use, can cause voltage spikes that will potentially damage the DC cord.
    • The 12 volt is intended to be used with systems that are either "positive hot" or "negative ground" only. If these details are unknown, speak with the manufacturer of the vehicle.

    How to Tell the Difference Between a 60 Series and 50 Series Machine

    1. Color
      • PR System One REMStar 60 Series Machines and Heated Humidifiers are charcoal gray with metallic silver side and instrument panels.
      • Original 50 Series PR System One units are dark gray with ivory colored side and instrument panels.
    2. Branding
      • The PR System One REMStar 60 Series Machines have the words "System One" in raised or embossed letters stamped in silver on both the machine and humidifier.
      • Original 50 Series PR System One units do not have raised lettering, the branding information is painted onto the unit.
    3. Machine and Humidifier Connections
      • PR System One REMStar 60 SeriesMachines and Heated Humidifiers have a 6 pin connection between the machine and humidifier.
      • Original 50 Series PR System One Units have a 4 pin connection between the machine and humidifier
      • PR System One REMStar 60 Series Machines and Heated Humidifiers have a mechanical connection between the machine and humidifier
      • Original 50 Series PR System One Units have 2 tabs on the humidifier that fit into 2 slots on the machine.
    4. Model Number Reference
      • PR System One REMStar 60 Series Machines label identification example: the label on the bottom of the PR System One REMStar 60 Series Auto CPAP lists: "REMStar Auto"; "REF" of 560P; and Serial Number identified by "SN". The number 560 references the part number of the machine.
      • Original 50 Series PR System One Machines label identification on the bottom of other versions of System One machines lists: Machine name; "REF" that does not have the number "6" in the second position from the left; and Serial Number identified by "SN". For example the label on the bottom of a PR System One REMstar Auto CPAP Machine with A-Flex lists "REMStar Auto" and "REF" of 550P. The number 550 references the part number of the machine.

    Regarding Heated Humidifiers, Please Note:

    The Shielded DC Cord for PR System One 60 Series Machines uses an 8 AMP Fuse. It comes packaged with two additional 8 AMP fuses. This same fuse is used when using the machine alone and when the heated humidifier and heated hose are used.

    When using the heated humidifier with a machine, the battery run time will be significantly reduced. Assume that the battery run time will be cut in half with the use of a heated humidifier. If the heated tube is also used, assume that the battery run time will be reduce by another quarter of the time.

    To get the longest run time out of a battery, it is suggested to use the CPAP without the heated humidifier or heated tube. To add some moisture to the air stream, consider using the humidifier as a passover by connecting the humidifier filled with water, but without the power turned on. In this way a heated humidifier is functioning as a passover humidifier.

    CPAP Video & FAQ

    Frequently Asked Questions (FAQs)

    What type of power does my CPAP need?
    Most CPAP, APAP and BiLevel machines today are designed to operate on both AC and DC voltage. 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 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:

    Can I travel by air with my CPAP?

    Yes, you can travel by air with CPAP equipment. Sleep therapy should be used every night and your equipment should be taken along when traveling. The following information is intended as a general guideline and does not reflect any particular airline's policy. Check with your airline carrier to verify their policies regarding CPAP / BiLevel equipment.

    • Generally in the USA, a CPAP machine and mask are NOT counted as a carry-on item.
    • The CPAP carry case must meet the size restrictions set for carry-on items.
    • Only items directly related to the medical treatment are included in the exception, any other items will count towards the carry-on allowance.
    • Some airlines ask that you contact them 48 hours prior to the flight, especially if you are planning on using the machine on the flight. Before traveling, check the policy for the airline you will be using.
    • Some airlines require documentation from a doctor stating the equipment is required by the user and must be kept with the user during travel.
    • In some cases, an on-board electrical outlet may be available. If you plan to use the equipment during the flight, a battery backup should be carried in the event the on-board power is interrupted.
    • Some locations in Asia and Europe may count the equipment used for Sleep Therapy as a carry on, but all airlines will allow it.

    Air Travel: Call your airline. Each airline has a different policy on whether or not you can use your CPAP while in flight, and if they have a power source available.

    Philips Respironics Travel Letter
    Will my CPAP operate overseas?
    An adapter may be required to plug a US power cord into a wall outlet in a foreign country. 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 sell contain power converters that enable the machine to operate on any AC current from 100 to 240 volts without any adjustment.
    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:

    How do I use a battery to operate my CPAP?

    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. 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.

    What type of battery should I use?
    For longer battery use, we suggest using a deep-cycle marine battery to power the machine. A deep-cycle marine battery is heavier than the ordinary battery, but it has many advantages. The battery is easily found at auto shops and it provides power to the machine for an extended period of time. For example, a CPAP machine set at 10 cm H20 and charged on a deep-cycle marine battery will usually last three nights before it needs to be recharged.

    There are small, portable battery packs that will operate a CPAP set at 10cm for at least one night, or about eight hours. 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.

    Some machines have batteries created to be used specifically with them only. Here are some of the machines we carry with integrated or specialized battery options:

    Transcend EZEX miniCPAP™ Machine
    Z1 Travel CPAP Machine
    Transcend Auto miniCPAP™ Machine with EZEX
    Z1 Auto Travel CPAP 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 that can set up as a fail-over, back up battery. Review the 'POWER' Tab on the machine page. sells Battery Packs to accompany your machine if an integrated battery is not available.
