Take Charge of Your Therapy

There’s no doubt that CPAP therapy requires a serious commitment to be effective, but committing to your treatment doesn’t have to mean sacrificing your freedom. Incorporating a CPAP battery pack into your therapy routine can help you manage the various challenges of travel and daily life. With a battery pack, you’ll never again have to worry about unexpected power outages or having your sleep machine fail at inopportune times. You’ll also be able to take your CPAP machine with you wherever you go without needing to coordinate complicated cord arrangements. And since most CPAP batteries are rated for hundreds of charging cycles, you can rest assured that your investment will keep you independent for years to come.

Backup Your Travel Plans

No more stressing over the logistics of powering your CPAP while away from home. A portable CPAP battery pack provides you with an additional layer of protection and peace of mind when you’re preparing to travel away from home. With so many sizes, run times, and charging options available, you can find the best solution for any sleep or travel scenario. Whether it’s a long weekend in the woods or a multi-week business trip, taking your CPAP battery pack with you can help ensure that you’re free to get a good night’s rest to matter where you travel.

Backup Your Main Power Source

Power outages are unpredictable and almost always occur at the least convenient times. By adding a battery to your sleep therapy routine, you can be assured that your CPAP will remain operational even if the power goes out. The ability to keep your machine running without interruption allows you to maintain consistent therapy and ensure the best possible results from your treatment plan. When your therapy relies on uninterrupted use, a CPAP battery pack provides the perfect backup plan.

Backup Your Backup

If you’re planning on going off the grid for a while, you may want to consider either taking multiple battery packs along with you, or opting for a model with an available solar panel charger like the Portable Outlet. Most CPAP batteries require an electrical outlet to charge, which can be tricky when you’re camping or in remote locations. But by opting for solar and having more than one supply kit on hand, you can be sure that you’ll always have a charged battery ready to go in case of emergencies and unpredictable energy availability.

Of course, your CPAP therapy is a priority, but so is living free and independent. With a CPAP battery pack, you can feel free to live the life you want without worrying about finding an outlet for your CPAP machine.

Capacity and Compatibility

While there are many considerations to take into account when it comes to choosing a CPAP battery pack, none are more important than the power source’s capacity to run your device and its compatibility with your CPAP machine. The capacity of your battery will determine how long you can use your CPAP machine without interruption and should be considered carefully based on your individual needs. Capacity is measured in watt-hours, meaning the higher the watt-hours, the longer your device can run.

Although external factors such as temperature and accessory use or misuse (i.e. cpap mask leak) can influence battery performance, a good rule of thumb is to match your CPAP machine’s draw in watt hours to the capacity of the battery you choose. Most CPAP machines draw about 30-60 watts. Some models, however, draw as many as 150 watts, and some small machines such as the ResMed Air Mini require less than 30 watts at maximum draw. Fortunately, most CPAP battery packs provide a range of watt-hours to accommodate different machines and draw levels.  

The other important factor when it comes to choosing a CPAP battery pack is compatibility. Not all batteries will work with every device, so it’s important to check the manufacturer compatibility list before purchasing. In addition, some models come with the connector cable kit and others require an adaptor. Certain battery packs, such as the Portable Outlet, are specifically designed to fit most CPAP machines on market today without an adaptor, including machines like the ResMed Air Mini, ResMed AirSense 10, and S9, as well as the Philips Dream Station, and iBreeze [].

Other Considerations

While capacity and compatibility top the list when it comes to choosing a CPAP battery pack, there are other features you’ll want to consider as you shop for an alternative or back up power supply for your sleep apnea device. Particularly if you’ve never used a CPAP battery before, you should take some time to become familiar with the features and benefits so you can select a CPAP battery that best fits your needs.

Power Loss Protection

Many newer models of CPAP batteries come with power loss protection, meaning the battery will automatically shut down if the voltage drops too low. This is a great safety feature that can help prevent damage to your CPAP machine in the case of an extended power outage or prolonged usage of the battery pack.

Uninterrupted Power Supply (UPS)

The UPS feature is found in many CPAP battery packs and provides users with the added benefit of automatic detection of low voltage. If you’re using a device with an alternating current (AC) power source and the AC power goes out, the UPS feature will automatically switch to battery power so that your therapy is not interrupted.


Taking your therapy with you doesn’t have to mean lugging around a heavy, bulky battery pack or an adaptor kit (or two.) Many CPAP batteries are designed to be lightweight and portable so you can take your therapy with you wherever you go without sacrificing comfort or convenience. If you’re planning on flying with your CPAP battery pack, you’ll want to check TSA and/or FAA guidance or contact your airline prior to flying as not all batteries are approved for airline travel.

Running Time (Battery Life)

CPAP Battery Running Time

Another important aspect to consider as you shop for a CPAP battery is how long the device will run on a single charge. Most are capable of lasting 8-10 hours when fully charged, but this varies depending on the wattage draw of your device and how you use it. For example, the ResMed AirSense 11 runs on a smaller 65-watt power supply, while the ResMed S9 and ResMed AirSense 10 run on 90-watt supplies. Thus, reviews from the ResMed AirSense 11 report longer run times even when using accessories like a heated tube. A properly fitting cpap mask and regular machine maintenance can also help prolong the life of your CPAP battery and maximize its potential.

USB Outage Options

Many CPAP battery packs also offer one or two ports to simultaneously recharge your phone or other small electronics device on the go. Not only is this a convenient feature, but it can also come in handy if you find yourself running low on battery while traveling. Whether you’re feeling free camping in the back country or flying to your next destination, having a backup power supply kit for all your electronic devices is always a good idea.

Charging Options

The time it takes for your CPAP battery to completely recharge will vary depending on the power cell itself, its capacity, and your device’s wattage. Recharging your battery to its maximum capacity is critical to maintaining consistent treatment. The process itself typically takes around 4-6 hours and can be done by plugging it into a wall outlet, car charger, or solar panel. It’s important to note that some CPAP machines require an AC power supply while other machines will run on DC power—meaning you may need a special adaptor to use a DC compatible battery.

Battery Indicator

Another feature you’ll want to look for as you shop is the low-voltage indicator. This will help you know how much charge your battery has and when it’s time to recharge or find an alternate power supply. Many models come with LED lights that signal when the battery needs to be charged, while others use a digital screen to display battery life.


As with any purchase, price is always a key consideration. Some machines are more expensive due to their enhanced features and quality components, while others are designed to be more affordable for budget-conscious consumers. As a general rule, it’s best to invest in a CPAP battery that is compatible with your device and offers the features you need without breaking the bank. You can spend as little as $200 or upwards of $1,000 depending on your needs and budget.


The wear and tear you put your battery through will no doubt impact its longevity. While most batteries are designed to be durable and withstand the elements, you should still take precautions such as storing it in a clean, dry environment. Make sure it’s not exposed to extreme heat or cold and avoid dropping it or subjecting it to any other kind of abuse.

Types of CPAP Batteries

Batteries are typically categorized based on their power cell type and charge capacity. The most common CPAP battery types are lithium-ion, lead acid, and lithium-iron-phosphate. Each type has its own unique advantages and drawbacks in terms of performance, size, weight, cost effectiveness, and lifecycle. The type of battery you need depends largely on your individual needs and expectations.


Lithium-ion batteries are the most common type of CPAP battery pack. They offer good performance, long life cycle, and relative affordability. Lithium-ion batteries are lightweight and the best choice for most travelers. However, since they have a shorter run time than lead acid battery packs, they may not be the best choice for those who require uninterrupted power over time such as long-term off-gridders.

Lead Acid

Lead acid batteries offer longer run times and are often used in larger applications such as motorhomes and backup generators. They provide a steady stream of power over time making them ideal for CPAP users who need battery power over an extended period. Unfortunately, lead acid batteries can be bulky and heavy which makes them less useful for people who are on the go.


Lithium-iron-phosphate batteries are the newest type of CPAP battery pack. They offer a longer life cycle than lithium-ion but are more expensive and weigh quite a bit more than their lithium-ion counterparts. These batteries are typically the best choice for CPAP users who need require constant power over long periods of time.

FAQ: Frequently Asked Questions About CPAP Batteries

Even if you’ve used a CPAP battery in the past, chances are that features have changed and improved, and you’ve got some questions. Here are some of the most common queries about CPAP battery packs.

What is the difference between a DC and AC compatible battery?

While many CPAP batteries come with a built-in AC plug (just like a wall outlet), others utilize DC power only. DC power is typically used in vehicles or boats and must be connected directly to the battery pack. AC compatible batteries can be plugged into a wall outlet for charging, while DC compatible batteries require an alternate source of power such as an inverter or generator.

How can my mask-fit affect my battery usage?

Quite simply, most CPAP machines respond to mask leaks by increasing pressure; this increased pressure puts a strain on the battery’s power source. Ensure a proper mask seal by regularly checking your mask for leaks, replacing any torn or worn mask components, and regularly cleaning your mask.

Which CPAP batteries have scored the highest in customer reviews?

While online reviews can be a good place to get a basic idea about the brands and models that are most popular with customers, it’s important to remember that reviews may be subjective (especially reviews from manufacturer’s sites). Ultimately, your own experience, rather than the reviews of other CPAP users, will determine which battery is right for you. Reviews can be a good starting point to get an idea of what to look for, but reviews should not be the only factor in your decision-making process.

Will my insurance provider or Medicare help cover the cost?

Unfortunately, as of now, CPAP battery packs as well as other parts and accessory items for CPAP machines are not typically covered by most major insurance plans. However, many items may be eligible for reimbursement under FSA or HSA plans, so it’s best to check with your plan administrator for more information.

Do I need a prescription for a CPAP battery?

No, no prescription is required to purchase a battery kit or other accessory items for most CPAP machines. They are generally available for purchase from online retailers as well as at most durable medical equipment stores.

What are some tips to ensure my CPAP battery performs optimally?

Turning off the heated tube functionality as well as turning off or removing your heated humidifier will help to reduce the power draw from your battery. Using heated tubing and humidification can reduce battery life by up to 80%. If you can’t go without these accessories, however, travel CPAP machines maybe a more suitable option as these machines are designed to draw less power. Additionally, keeping your battery charged when not in use and checking for connections or frayed wires will help ensure a long, lasting, reliable performance.

Camping with Your CPAP is Not Only Possible, it’s Dreamy!

Your CPAP Battery will let you go camping again

Remember how good it felt when you finally got a good night’s sleep thanks to your CPAP machine? Imagine how great it would feel to get a good night’s sleep just like that under a blanket of stars in the middle of nowhere. Or maybe you’re more of an RV camper, with all (or most) of the comforts of home. No matter where or how you camp, a CPAP battery kit can provide you with continuous therapy and freedom to travel and explore without worry, even if you’re going way off-grid for an extended period of time.

For RV campers, your best battery bet will depend on the type of vehicle you have and how you plan to power it. For instance, if your RV is equipped with a generator and AC power, you’ll likely need an AC compatible battery pack. But if your RV is equipped with a cigarette lighter plug, then a DC powered battery pack may be the best option for you as CPAP machines themselves run off DC power supply, and battery options that offer DC plugs are generally the most efficient.

If you plan on camping out in the elements, a lightweight lithium-ion battery is your best solution for comfort and convenience. These portable kits are ideal for free-spirited adventurers or anyone who may not have access to electrical outlets when they travel. For CPAP users who are looking for sustainable ways to power their CPAP machines, solar panel chargers are a great option. Solar panels are an eco-friendly, reliable way to charge your CPAP battery in even the most remote locations. Online reviews for CPAP battery solar chargers report a full charge after only 3-4 hours in direct sunlight.

Traveling and camping with your CPAP machine doesn’t have to be a hassle! With the right accessories and knowledge, you can enjoy freedom and comfort no matter where you travel. So, get out there, feel free to explore, and sleep peacefully wherever you may travel!

You Don’t Have to Go Without (And You Know You Shouldn’t)

Even though you may be tempted to do without your CPAP therapy if you’re heading out on a short trip, remember that it’s important to maintain your regular sleep routine and stick with the therapy you’ve been prescribed. The risks of foregoing your treatment plan far outweigh the convenience of going without it, even for just a night or two. When you go without your prescribed treatment, you put yourself at greater risk for an array of health issues, from headaches and fatigue to more serious conditions like hypertension or stroke.

Fortunately, portable CPAP batteries make it easier than ever to take your therapy with you wherever you may travel. With the right set up, you can stay connected while you’re flying in a plane or camping out in the great outdoors. Enjoy the freedom of uninterrupted sleep and rest easy knowing that you’re taking care of yourself and your health. Shop for your new CPAP battery pack today and see how good independence can feel!.
