If you have sleep apnea, you likely rely on your CPAP machine to enjoy restful sleep, sharper focus, and longer-lasting energy. But what happens when you experience an emergency, like a power outage, or you want to go on a vacation where you may not have access to power?


A CPAP backup battery has become essential equipment for anyone with sleep apnea. They come in handy while camping, flying, and during unexpected emergencies and brief overnight power outages. Fortunately, portable CPAP batteries have come a long way in recent years, and backup power solutions allow you to experience uninterrupted therapy in any situation. Let’s explore the importance of CPAP backup batteries, key features to consider, user reviews for top-sellers, tips for maximizing CPAP battery runtime, and more. 

Reasons to Have a Backup CPAP Power Solution:  

If you have sleep apnea, it’s crucial to prioritize CPAP therapy in all situations in order to experience quality sleep and optimum energy and focus. Interruptions in therapy can lead to poor sleep quality, increased risk of disease, and a decline in overall well-being. Scenarios where power supply might be interrupted include:

    • Power Outages: Unexpected power outages can happen anywhere due to natural disasters, technical issues, or maintenance work, leaving you without power. A CPAP emergency power supply will power your machine during these times. During brief power outages, most CPAPs will automatically switch to battery power so that your therapy is not interrupted. It also allows you to be prepped for prolonged power outages due to natural disasters. For example, according to the U.S. Energy Information Administration, Hurricane Ian left 2.6 million Floridians without power for two weeks. A portable CPAP battery can help you sleep better, even in unexpected stressful situations where sleep matters most.

  • Camping Trips: If you enjoy the great outdoors, camping trips can pose a challenge for CPAP therapy. Don’t skip your therapy just because you enjoy the wilderness. A CPAP battery for camping ensures you can enjoy your outdoor adventures without compromising your health.

    • Traveling: Long travel days, especially on planes, can disrupt your CPAP routine and your general sleep schedule. Bringing a battery can help you stick with your CPAP therapy and decrease your risk of travel fatigue. Different countries may also have varying power outlet standards, requiring adaptors or converters. You may also arrive at your room and realize the outlet is too far from the bed. A portable CPAP battery offers you peace of mind when treating your sleep apnea from anywhere. 

    Key Features to Look for in CPAP Backup Batteries

    When selecting a CPAP backup battery, consider several key features to ensure it meets your needs. You’ll want to weigh your options between weight, runtime, and price. For example, if you want to go camping for an extended period, you may prefer a longer-lasting battery over something lighter. On the other hand, traveling as light as possible may be your priority. In any case, here are the main components to consider before purchasing your travel CPAP battery. 

    CPAP Runtime

    One of the most critical aspects of a CPAP backup battery is its runtime. The battery should be able to power the CPAP machine for an entire night's sleep, typically 8 hours or more. Longer runtime ensures uninterrupted therapy, even during extended power outages or multi-day camping trips. Investing in a solar panel is another great option to charge your battery without power.

    CPAP Compatibility

    Before you buy, make sure your CPAP backup battery is compatible with your specific CPAP model. Different CPAP machines have varying power requirements, and an incompatible battery can lead to inefficiency or even damage your CPAP.

    CPAP Battery Size and Weight

    Size and weight are other crucial factors, especially if you travel frequently or enjoy camping. A portable, lightweight, easy-to-carry CPAP battery for camping and traveling allows you to maintain your therapy routine without much excess weight. However, portability may not be your top priority if you don’t plan to travel much with your battery. 

    CPAP Battery Charging Options

    Versatile charging options enhance the convenience of using a CPAP backup battery. Many batteries can be charged via solar panels and car adapters. Some batteries may only be able to charge your CPAP, while others may have a standard outlet to charge other items, like a laptop.

    CPAP Flying Regulations 

    ​​You can use most CPAP batteries on an airplane, but there are some essential guidelines to know. Typically, you can carry up to two lithium batteries at 101–160 Wh. Be aware that lithium-ion batteries aren’t allowed in your checked baggage. TSA encourages you to carry it on the plane with you.

    Your CPAP machine is considered medical equipment, so airlines should permit it without counting it as part of your carry-on limit. However, consider contacting your airline a few weeks before your flight to verify their policies and ensure they approve your specific battery. It can also help to carry a note from your doctor stating that your CPAP is medically necessary, along with a copy of your CPAP machine’s FAA compliance notice.

    Tips for Traveling with Your CPAP Battery 

    A backup CPAP battery can help you be prepared for emergencies and outdoor adventures. Include a CPAP backup battery in your emergency preparedness kit to ensure you're ready. In addition to food, water, and other essentials, having reliable CPAP power solutions ensures you can maintain therapy even during prolonged and unexpected power outages. To make the most out of your CPAP backup battery, here are some practical tips to extend its runtime and ensure efficient use:

  • Optimize CPAP Settings

  • Adjusting your CPAP machine's settings can significantly impact battery life. For example, if it doesn’t compromise your therapy, you may want to turn off optional features like humidification and heated tubing, which can help conserve battery power. 

  • Use an Inverter

  • Use an inverter to manage your CPAP machine's power consumption. It converts the battery's DC power to the AC power required by the CPAP, improving efficiency and extending battery runtime.

  • Regular Maintenance

  • Regular maintenance of your CPAP machine and battery ensures optimal performance. Clean the CPAP device as the manufacturer recommends and check the battery for any signs of wear or damage. Check out our CPAP replacement guide for more details. Proper maintenance can prevent unexpected failures during critical times.

  • Plan Ahead

  • If you know you'll be away from a power source for an extended period, plan accordingly by fully charging your CPAP backup battery before heading out. If possible, you may want to carry a spare battery. This proactive approach can help avoid interruptions in therapy without worrying about charging your battery on the go.

  • Invest in a Solar Panel

  • A solar panel allows you to charge your CPAP battery anytime you can access sunlight. This can allow you to recharge your battery while going on a remote adventure, like backpacking through the wilderness or a weekend of sailing. Click here to see our top-selling solar panels
