Portable CPAP Batteries and Solar Chargers

CPAP batteries allow you to power your CPAP machine without a wall outlet, and some can be used as a battery backup in the event of a power failure. Avid campers and frequent travelers can benefit from bringing along a CPAP battery or two to make travel plans more versatile. Most CPAP batteries we carry are FAA compliant and can be used in-flight. They can power a travel CPAP for multiple nights and can even handle a full-sized unit for a night or two without humidification.

Helpful Tips On Portable CPAP Battery Packs

Whether you’re a frequent traveler or just want a backup battery for your home CPAP machine, CPAP batteries can help you take your therapy on the go and protect you in the event of a power outage. With options for AC, DC, and even solar charging, a CPAP backup battery can bring much-needed flexibility to your life.

Why Buy a CPAP Battery?

The best CPAP battery can power a CPAP machine for up to two nights, though you’ll most likely need to recharge after each use if you use a humidifier. Some CPAP batteries, such as the Universal Portable Outlet UPS, can be used as an uninterruptible power supply in case your power goes out in the middle of the night. With a battery backup, you won't have to worry about waking up due to your sleep apnea symptoms. As soon as you lose conventional power, your CPAP machine will seamlessly transfer to battery power. Neither your sleep nor your CPAP therapy will get interrupted.

Other battery options will require you to manually switch your power supply in the event of unexpected power loss. There are external CPAP machine batteries and internal options. We also carry CPAP batteries that will charge both your CPAP machine and your mobile phone or another personal device. You can even find extended-life batteries that will run your CPAP machine all night along with your heated humidifier and other accessory components. With CPAP batteries, you won’t need to worry that you’ll be without your sleep apnea therapy if you’re away from home or there’s a power outage. With the right portable CPAP battery, you won't have to pass on camping trips. CPAP batteries also allow you to take your machine with you when traveling overseas; just note that you’ll also need an outlet adapter when traveling to areas with different electrical outlet types. Best of all, most CPAP batteries are also FAA-approved for in-flight use.

Having a battery for CPAP machine continuity can also give you peace of mind during times of inclement weather. These accessories can be especially important to have on hand when power outages are likely. Whether winter snowstorms routinely cause power loss in your home or utility lines go down due to springtime winds, a CPAP battery will reliably keep your device powered up.

How to Choose a CPAP Battery

When choosing a battery for your CPAP machine, you always want to make sure that it's compatible with your device. It's additionally important to verify that your new portable battery boasts the capabilities and features you need. For instance, if you intend to use your battery for travel, you should make sure that it's lightweight and has sufficient power for supporting your machine and all of your CPAP accessories throughout the entire night. If you intend to use your CPAP battery for continuous machine operation in the event of a power outage, look for an option suited for this purpose. Depending on the battery you choose, you may need an inverter or converter. Check your product specifications on to identify what additional accessories may be needed.

It is important to determine how long you will need your battery to last. If you are traveling for multiple nights away from a recharging power source, pick an option that can accommodate that need. Also keep in mind that if you need to use a humidifier, it will deplete the battery quicker.

Frequently Asked Questions

  • How Long Do CPAP Batteries Last?

    Depending on the battery type, CPAP batteries can last anywhere from one night of sleep—8 to 12 hours—to multi-nights of rest—up to 6 nights. 

  • How Do I Get Longer Runtimes?

    For longer battery runtimes, determine which additional accessories or comfort features are most important to your CPAP therapy experience. For instance, if you need to use a humidifier or heated tube, then that will deplete your CPAP battery quicker. 

    • Turning off your humidifier will increase your battery’s runtime. 
    • You can also stack more than one battery on your setup to get double the amount of runtime like with the ResMed Power Station II.
    • Use a Travel CPAP instead for more efficient energy consumption.
    • Use a Solar Charger if you're going off-grid.

Surprising Battery Life

I am getting three full nights of sleep on a single charge of this battery. Amazing! It is easy to use with a simple design. It is designed to make use of the CPAP system's AC adapter instead of having one itself. It can also be used "in-line" with the larger system to effectively function as a battery backup so if your power goes out, you don't wake up being suffocated by your mask! It's expensive but worth it if you go weekend camping a lot!
