CPAP Battery Power

October 27, 2017 | CPAP Benefits |

For patients who treat sleep apnea with CPAP therapy, it is always best to prepare for the unexpected power outage. This is particular true if you live in an area prone to rough weather (hurricanes, tornadoes, snow avalanches) or natural disasters (ie, forest fires or earthquakes). But even if you live in a stable environment, power outages are often unforeseeable and can leave you without the therapy you need. Therefore, we recommend always having an alternative battery on hand.

In general, we find that our CPAP customers are much more informed about the importance of compliance. Going a night without CPAP therapy, for most users, is something they try to avoid at all costs. Yet, surprisingly, most PAP users do not have an alternative power source available in case of an unforeseen circumstances or last-minute travel.

A recent survey of 150 people found that nearly 85% of CPAP users always take their CPAP when they travel.

From a health perspective, this is terrific news. According to WebMD, “Even one night of not using the machine can make you sleepy the next day.” And, when use is intermittent, the benefits are reduced considerably.

We asked our survey respondents whether they have ever used a CPAP battery to power their machine. Given the low availability of effective batteries, only 13% of our 158 respondents have ever used a CPAP on a battery! However, only 21% responded that they did not have an issue with frequent power outages.

Only 13% CPAP Users Power machines with batteries

One year later, we asked the same question again with slightly different results. Only 29 of our 333 respondents used a battery to power their CPAP machines. That’s less than 10% of CPAP users who own a battery backup for emergencies or travel. It’s also a slight decrease from 13% to 10% of CPAP users! We can only speculate that our CPAP users are either traveling less frequently or are not concerned about power loss.

Only 10% of CPAP users own a backup CPAP battery

In fact, 27% of CPAP users are unaware that new CPAP lithium ion batteries are lightweight, very portable, and relatively inexpensive. In fact, many of our subjects did not even know CPAP batteries were available to power their machines!

People on CPAP do not necessarily need a battery backup unless they are going somewhere without access to power. Also, day-long power outages are fairly uncommon across most of the United States.

CPAP Battery Backup – It’s Not Just for Camping!

Unfortunately, as you may now realize, a backup battery for your CPAP can be useful in many circumstances not just camping. Hopefully, the recent forest fires passed you without much trouble. The next time power is out in your area, a CPAP battery can deliver uninterrupted power for your CPAP therapy. 

As you will see, CPAP battery backup is easy, affordable, and offers peace of mind. A really impressive CPAP battery backup system is the Freedom CPAP Battery. It replaced many of the older batteries with more unique features, a smaller size, and longer life. 

In addition, we asked our users whether their CPAP therapy had ever been interrupted by a power outage.

Only 33% of CPAP users have experienced a power outage that interrupted therapy

Flooding in Houston, hurricanes off the Florida coast, tornadoes in the Midwest, and forest fires in California have knocked out power for extended periods. It made people realize the need for a backup CPAP battery system. Fortunately, people with a CPAP battery backup for their CPAP machines can breathe a sigh of relief.

We asked our 29 CPAP Battery users if they were satisfied with their backup batteries and almost all of them were highly satisfied with the backup battery option.

How Batteries Power a PAP Machine

Most PAP machines work with either AC or DC power. Wall outlets in the United States produce 110 volts while in Europe outlets produce either 220 or 240 volts. Most batteries output 12-volt DC power. There are several types of batteries that can power a PAP machine. In some cases, the CPAP machine will require an inverter fromDC to AC power. If an inverter is required, it will reduce the number of hours received from the battery. It’s important to check with your equipment provider to determine what type of equipment and power cords you will need.

Longest CPAP Battery Power Source

The deep-cycle marine battery will power PAP machines the longest. With some pressure settings your PAP machines can run up to 3 days. You can buy a deep-cycle marine battery at any auto supply store. They are great for RVing and for when the power goes out at home.

You can purchase the inverter and power adapters necessary for your PAP machine from our battery power cables page here.

Another Battery that Can Power a PAP

Many manufacturers have recognized the need for batteries specifically designed to power PAP machines. In 2019, there are several PAP machines that have integrated or specialized batteries. These include:

DreamStation Go Travel CPAP with Battery Pack

  • Only 1.86 lbs with built-in power supply for fewer parts
  • Integrated rechargeable battery (optional)
  • Integrated heated humidification powered by tap water (optional)
  • Complies with FAA standards for in-flight use

HDM Z2 Auto Travel CPAP Machine

  • Only 10.5 ounces and ultra-small
  • Integrated battery (optional)
  • Waterless humidification
  • Complies with FAA standards for in-flight use

ResMed AirMini Auto Travel CPAP Machine

  • Only 10.6 ounces and fits in the palm of your hand
  • Waterless humidification
  • Ultra-quiet operation
  • Complies with FAA standards for in-flight use

Lithium ion batteries are lighter, smaller, and have options like USB ports and dashboards that indicate battery life. Additionally, all major brands of CPAP machines work with battery power using an adaptor.

The machines with integrated batteries are the easiest to connect. We asked our 29 survey respondents what type of battery they were using and most of them used a rechargeable battery.

CPAP Battery Power Packs

PAP Battery Packs offer an all-in-one power solution using the DC power adapter connected directly to a battery pack. Battery packs can power a PAP from 8 to 24 hours depending on pressure settings. Most battery packs cannot power heated humidifiers. Also, passive humidity (supplied by the humidifier without turning on the heated option) can increase the power usage. As a result, 66% of survey respondents indicated that the battery does last long enough.

Battery packs can be expensive. But for travelers, and campers, and those living in areas prone to power outages, a battery pack is worthwhile.

Here are a few different battery pack options currently available at The CPAP Shop:

Medistrom Pilot-12 Lite CPAP Battery Backup Power Supply (for Respironics)
FAA-approved for use in remote locations where main power is not available, such as camping, road trips and during air travel.

Medistrom Pilot-24 Lite CPAP Battery Backup Power Supply (for ResMed)
The built-in USB port allows the Pilot-24 Lite to power countless handheld electronic devices, including mobile phones and cameras. It can also be used as a charging station for various electronic devices.

Freedom Travel CPAP Battery 

Since many people won’t spend over $300 on CPAP battery power. The Freedom Travel CPAP Battery is priced at only $269.95! This battery is compatible with all PAP machines (although some machines require a specific dc cable). It is lithium ion and meets all current FAA requirements. The battery can be used to power other devices that use a 5V USB port. This includes cell phones, and tablets and it even has an option for charging in a vehicle or by solar power.

It’s Easy to Connect CPAP Battery Packs to Tour CPAP Machine

Over the years, we’ve posted several videos on our site that outline how to connect batteries to CPAP machines. We want users to be able to continue their CPAP therapy even during times when power is not available. A CPAP battery pack would also give them the freedom to travel anywhere.

Some of the machines have special converters that must be used when hooking up to CPAP battery packs. All of the batteries have approximately 6 ft cable lengths. When using battery power, you don’t have to be right next to the power source.

In addition, our survey respondents think it is very easy to connect their machines to a battery. Some of the older machines need an inverter in order for the battery to work. The CPAP machine plugs into the inverter, and the inverter plugs into the battery. A small amount of battery power is lost, but not enough to affect therapy.

Most CPAP users find it easy to connect to a battery

We produced a video about several different CPAP machines and how you can use them with a CPAP battery. You can see specs for the other batteries by watching the video here.

Chris Vasta demonstrates in a recent video how to connect the Philips Respironics Dream Station machine to its battery. In the video, Chris sets up the battery so that it will kick into action if the power goes out. For the demo, he uses the lithium ion Phillips Respironics travel battery. It weighs only 2.25 lbs, and is FAA approved for airline travel. As Chris quickly demonstrates, all it takes to power a CPAP machine with this battery is a simple one-cable connection.

    Hi I recently started using a Resmed Air Sense 10 CPAP machine. Could you please refer me to the correct battery backup for this machine and the price? Thank you!

    • Chris Vasta

      Hello, Tim. You can use the Universal Freedom Battery or the Medistrom Pilot 24 battery with your Resmed Airsense10 machine. The Freedom battery is $339.95 with the cable you need for the Airsense10 machine. The Medistrom Pilot 24 battery is $339.00 and used the cord from your machine to recharge the battery. Here is the link for the Medistrom 24 battery: https://www.thecpapshop.com/medistrom-pilot-24-lite-cpap-battery-for-resmed. Here is the link for the Freedom battery: https://www.thecpapshop.com/freedom-travel-cpap-battery-bundle. According to the manufacturer if your pressure is 10cm, with the freedom you should be able to get around 16 hours, and with the Medistrom 24 battery at a pressure of 10cm you should be able to get around 12 hours.

      • kenneth nellis

        You can also use a maxoak battery backup system for the resmed airsense 10 machine. It is priced a bit lower than the Freedom and Medistrom battery systems and it gets very good reviews.

        • Chris Vasta

          The batteries we provide are all verified by the manufactures and I am afraid I would not be able to comment on the Maxoak batteries, regarding compatibility or reliability. Thank you for bringing it to our attention.

  • Charlene skonberg

    We have a BiPap machine. What battery pack would last all night?

    • Chris Vasta

      Hi Charlene, Bipaps can be tricky. We would recommend the Freedom battery as this can be used with most cpap and bipap machines – https://www.thecpapshop.com/freedom-travel-cpap-battery-bundle
      Please note, you would have to purchase the double battery configuration in order to get 1 night out of the bipap machine. This is also with the humidifier off and any additional features such as Flex or EPR turned off. With the double battery config and the humidifier and features off, you should be able to get 1 – 3 nights from the batteries. This run time is also dependent on what the pressure settings are.

  • Bob

    Can you keep your CPAP battery plugged in all the time in case of a power outage?

    • Chris Vasta

      Hi Gregory, yes most of the batteries we sell are backup ready. They can be plugged in all the time in case of outages.

  • juan escobar

    Hello,

    What is the price of the 222 battery pack? Do you deliver to Canada and, if so, what would be the shipping cost?

    Thanks,

    J

    • Chris Vasta

      I’m sorry, but that product was discontinued. It is no longer available. It has been replaced by the Freedom battery. We would require an address in the US, to ship a lithium ion battery. Thank you

  • Jill

    There’s got to be a less expensive way. For the sake of health, and for those who cannot afford hundreds of dollars, can’t we just buy a 12V battery somewhere and make it work? Help!

  • William Smith

    Hi! This is interesting. My husband needs something like this when power goes off.

  • thomas mott

    Nice easy-to-follow presentation. I have a Remstar SE System 1. Will this unit work with this model? Also, please give me the cost. Thanks!
