Length

The DC-24 Converter For S8 ResMed VPAP Auto 25 and VPAP ST Machines consists of the converter box, a 14" cord extending to the cigarette lighter socket and a 48" cord extending to the machine end DC connection pin.

Word of Caution to RESmed S8 and S8 II Machine Users

YOU MUST USE THIS converter in conjunction with any battery source, when using ResMed VPAP Auto 25 and VPAP ST Machines. Failure to do so can result in damage to your CPAP.
This is the only product that you should use to power the VPAP ST or VPAP Auto 25 from a DC source. If your ResMed CPAP machine is not listed, then visit the DC-12 Converter For S8 Machines for more options.

If you would like to use a heated humidifier, then this cord will not work. You will need a Pure Sine Wave DC Inverter to generate a clean, Alternating Current (a/c) power. Inverters without a Pure Sine signal may fit, but will blow out the S8 power supply (no kidding, we have found out the hard way). The polarity is different from most 12 volt cables and the inverter provides needed power smoothing.
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.


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.

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.

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.
How can I compare different machines?
We work very hard to provide many different ways for our customers to compare products. Here are the machine product guides we have created and maintain:

Which CPAP masks work on which machines?

Any mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:

  • ResMed AirFit™ N20 Nasal Mask
  • ResMed AirFit™ F20 Full Face
  • ResMed AirTouch™ F20 Full Face
  • ResMed AirFit™ P10 Nasal Pillow

When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.

How do I choose the machine that is right for me?
We provide our customers with many tools to make informed decisions about their machine purchases. Options include:
What comes with my machine?
Machines come with a six foot hose, power cord, at least one filter, and manuals. Most manufacturers include a carrying case which is designed specifically for their equipment. CPAP, APAP, and BiPAP machines do not come with a delivery system or mask. CPAP masks must be purchased separately.

To see the list of what specifically comes with each machine, you can Browse for a machine. Then on the product page, click the "Specs" tab to see a full list of what comes with the machine.

Are prescriptions required for mask, machine, humidifier, and EPAP purchases?

Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine, humidifier, or EPAP therapy, including Provent and Bongo RX. You will also need a prescription to purchase the Nightbalance POSA device.


We provide many easy ways to get your prescription:

  • We can request your prescription for you! When you checkout, just let us know you would like us to request your prescription, or you can log into your account to have us request your prescription.
  • Fax your prescription to our toll-free fax number: 866.353.2727, or our international fax number: 713.541.7377
  • Email your prescription to cpap@cpap.com
  • Upload your prescription in your account, under the Prescriptions Section
  • Ask your doctor to fill out our prescription form. We have both a standard prescription form and an EPAP prescription form.


For more information on prescriptions, please see our Prescription Section of the Learning Center.


What are the CPAP, BiPAP, Sleep Apnea, and Oxygen related HCPCS, CPT or billing codes?

E1399 is Miscellaneous and is used for other CPAP and Oxygen items.
What maintenance is required on machines?
The only care a CPAP, APAP or BiPAP machine requires is to clean or change the filters at the air intake. This keeps the internal parts from accumulating dust. Fine paper filters should be changed out every 30 days, or when they appear soiled. Foam washable filters should be rinsed with clear running water once a week, allowed to air dry, and reinserted.

Here are some other suggested actions to care for your machine:
  • Keep the area around your machine clean by removing any dust from the area to improve the air quality delivered to your machine and to you.
  • Keep the air intake of the machine unblocked. Curtains, bedding, and papers can easily block the air intake of your machine, reducing the airflow.
  • If a humidifier is used with your therapy, do not pick up the machine with the humidifier attached. With most machines it is easy to spill water from the humidifier chamber into the machine causing damage. Manufacturer warranties are voided by water damage to the machine. To avoid this, remove the chamber from the humidifier and then remove the humidifier from the machine rather than transporting them together.
  • If a humidifier is used, empty the water from the chamber every morning. Accidents happen. If a family pet or family member moves the machine and humidifier with water in the chamber it is more likely that water could be spilled into your machine. Water damage to a machine voids the manufacturer warranty.
What does CPAP therapy do?
CPAP therapy provides a constant airflow which holds the airway open so that uninterrupted breathing is maintained during sleep. It is traditionally provided through a nasal mask that seals around the nose to maintain the pressure level.

I Can Go Camping

Verified purchase | Mar. 18, 2011 | Verified CPAP.com Customer
With this small converter I am now able to go campinging with only one battery. I used to have to use three marine batteries and an inverter to get through the night but with this converter I am down to only one battery.
