More Details on Our Top Picks
Pilot-24 Lite 95Wh CPAP Battery Backup Power Supply for 24V CPAP Machines
The Pilot-24 Lite stands out for its compact size and TSA approval, making it an excellent choice for travelers who prioritize portability without sacrificing runtime. Compared to larger options like the BLUETTI X30, it offers a much lighter weight—only 1.3 pounds—while providing up to 16 hours of power for 24V CPAP devices. Its durable aluminum case and industrial-grade cells contribute to reliability, but the tradeoff is that cables for some devices are sold separately, and runtime varies with device settings. If you need a straightforward, airline-friendly backup for 24V machines, this is a top pick.
Pros:- Extremely lightweight and portable, ideal for travel and outdoor use
- Up to 16 hours of runtime on a single charge
- TSA and FAA approved for air travel
- Durable construction with industrial-grade cells
Cons:- Cables for some compatible devices are sold separately
- Runtime depends heavily on device pressure and settings
- Limited to 24V CPAP machines only
Best for: Travelers who need a lightweight, airline-approved backup for 24V CPAP machines
Not ideal for: Users with multiple devices requiring longer runtime, as this model is limited to about 16 hours for most 24V devices
- Battery Capacity:95Wh
- Weight:1.3 lbs
- Battery Cell Type:Lithium Ion
- Recharge Time:2-3 hours
- Compatibility:24V CPAP machines including AirMini, AirSense 10, S9, prismaSMART, Luna, DreamStation Go
Our verdict“Best suited for travelers seeking a lightweight, airline-friendly backup for 24V CPAP devices with moderate runtime needs.”
BLUETTI CPAP Battery Backup X30 297Wh Power Supply with Comprehensive Set for AirSense 10, AirSense 11, S9, AirMini, AirCurve 10, Travel Camping Emergency Power DC12/15/24V & USB5V
The BLUETTI X30 offers nearly triple the capacity of the Pilot-24 Lite, making it better suited for those who need extended backup power for multiple nights or larger devices. Its 297Wh capacity and multiple DC/USB outputs provide flexibility, especially compared to the Pilot Flex, which supports dual voltages but with a slightly smaller capacity. While heavier at 3.9 pounds, it comes with a full set of cables for quick setup, ideal for camping, travel, or emergency prep. The main tradeoff is that its capacity may still fall short for multiple nights of heavy use, and proper handling is essential for safety.
Pros:- Large 297Wh capacity supports multiple nights of sleep therapy
- Multiple DC and USB ports for versatile device charging
- Complete set of cables simplifies setup
- Reliable backup during power outages or outdoor adventures
Cons:- Weight of 3.9 pounds may be less convenient for frequent travelers
- Limited capacity for extended multi-night use with high-pressure devices
- Requires careful handling to prevent safety issues
Best for: Users who want a reliable, versatile backup with enough capacity for longer trips or multiple devices
Not ideal for: Light travelers or those needing ultra-light gear, as the extra capacity adds weight and bulk
- Capacity:297Wh
- Weight:3.9 lbs
- DC Output Ports:12V/5A, 15V/4A, 24V/4A
- USB Port:5V/2.5A
- Included Cables:5 cables with color labels
Our verdict“Ideal for those needing longer-lasting backup power for multiple devices during travel or emergencies, accepting extra weight for capacity.”
Pilot Flex Charcoal 98Wh CPAP Battery Backup Power for 12V & 24V Machines
The Pilot Flex offers support for both 12V and 24V CPAP machines, making it a flexible choice for users with different device requirements. Its 98Wh capacity is comparable to the Pilot-24 Lite but supports a broader range of models, including AirSense 11 and other 12V/24V devices. Compared to the NiteOwl, which features swappable cells and a larger capacity, the Pilot Flex emphasizes quick recharging and TSA approval. However, for extended use or multiple nights, its runtime may be insufficient without multiple batteries, and cables are sold separately.
Pros:- Supports both 12V and 24V devices for flexibility
- TSA and FAA approved for air travel
- Quick recharge time of 2-3 hours
- Durable aluminum case with industrial-grade cells
Cons:- Limited runtime for multiple nights or high-pressure settings
- Cables for some devices are sold separately
- Requires multiple batteries for extended backup needs
Best for: Travelers with multiple device voltages or those needing quick recharge and TSA approval

- Weight:1.2 lbs
- Compatibility:12V & 24V CPAP machines including AirSense 11 and AirMini
- Recharge Time:2-3 hours
- Dimensions:17 in³
Our verdict“A versatile, dual-voltage backup suitable for varied device configurations, best for short trips or backup needs.”
NiteOwl CPAP Backup Power Supply & Travel Battery, 2nd Generation, Swappable 150Wh Cell Pack, Compatible with Most Popular CPAP Devices, Portable and TSA Approved
The NiteOwl 2nd Generation offers a unique swappable 150Wh cell pack, extending runtime for users who need longer power during travel or camping. It supports a wide range of popular CPAP models, including ResMed, Philips, and React Luna, making it versatile. Its compact, TSA-approved design makes it suitable for frequent travelers, especially those who prefer swapping batteries instead of waiting for charging. The main consideration is that battery capacity alone may not suffice for very long trips without swapping, and recharging depends on using the existing CPAP charger.
Pros:- Swappable 150Wh cell pack extends runtime significantly
- Compatible with multiple popular CPAP models
- TSA and FAA approved for air travel
- Lightweight and portable design
Cons:- Limited to CPAP device compatibility
- Requires use of existing charger for recharging
- Battery capacity may need multiple swaps for extended use
Best for: Frequent travelers and campers needing extended runtime with easy battery swapping
Not ideal for: Users seeking a single, high-capacity backup for multiple nights without swapping batteries
- Battery Capacity:150Wh
- Number of Batteries:1
- Compatibility:ResMed AirSense 10/11, AirMini; React Luna G3; Philips DreamStation 1/2
- Warranty:1 year
- Dimensions:varies
Our verdict“Great for frequent travelers who value extended runtime and easy battery swapping over bulkier solutions.”
EnginStar Portable Power Station 300W 296Wh Battery Bank with 110V Pure Sine Wave AC Outlet for Outdoors Camping and Emergency
The EnginStar Power Station provides a larger capacity (296Wh) and a 300W pure sine wave AC outlet, making it suitable for powering more than just CPAP machines—such as phones, laptops, and small appliances. Compared to dedicated CPAP backups like the BLUETTI X30, it offers more versatility, especially with multiple output options, including AC. However, the 300W limit means it may not handle high-power devices simultaneously, and the absence of a solar panel means it relies on wall or car charging for recharging. This makes it ideal for outdoor adventures or emergency scenarios where multiple devices need power.
Pros:- Multiple output ports including two 110V AC outlets
- Supports solar, wall, and car charging for flexible recharging
- Lightweight and portable for its capacity
- Safe with advanced battery management system
Cons:- Solar panel not included, adding to overall cost if needed
- Limited to 300W output, not suitable for high-power appliances
- Battery capacity may be insufficient for extended multi-device use
Best for: Outdoor enthusiasts or emergency preppers who need to power multiple devices, including CPAPs, in one compact unit
Not ideal for: Travelers requiring lightweight, dedicated CPAP backups, as this unit is bulkier and designed for broader use
- Capacity:296Wh
- AC Output:300W
- Dimensions:9 x 5.5 x 7.5 inches
- Weight:6.5 pounds
- Outputs:8 ports including two 110V AC, USB, DC
Our verdict“Best for outdoor or emergency scenarios where powering multiple devices, including CPAPs, is necessary in a portable form factor.”
EASYLONGER ES720 PRO CPAP Battery Pack, 276Wh, Portable Power Supply for ResMed, Philips, Luna TravelPAP
The EASYLONGER ES720 PRO stands out for its impressive 276Wh capacity, making it capable of powering most CPAP machines for 2-3 nights. Compared with smaller options like the Pilot-24 Lite, this model supports longer trips and emergencies without frequent recharges. Its multiple recharging methods, including solar, AC, and car adapters, add flexibility for outdoor and travel use. The upgraded digital display provides real-time status, and the pass-through feature prevents sleep interruptions during outages. However, its high capacity means it’s heavy and bulky, making it less ideal for those prioritizing portability. Additionally, its capacity exceeds airline limits, restricting air travel use without special arrangements.
Pros:- High-capacity 276Wh battery supports multiple nights of use
- Supports solar, AC, and car recharging for outdoor flexibility
- Digital display provides real-time power status
- Pass-through charging ensures continuous sleep during outages
Cons:- Heavy and bulky, less suitable for daily carry
- Not approved for air travel due to high capacity
Best for: Travelers needing a reliable, multi-night backup with versatile recharging options, especially for camping or extended trips.
Not ideal for: Frequent flyers seeking a lightweight, airline-friendly option, since its size and capacity limit air travel compatibility.
- Capacity:276Wh
- Compatibility:ResMed AirSense 11/10, AirCurve 11/10, AirMini, Luna TravelPAP, Philips DreamStation & DreamStation 2
- Charging Time:4-5 hours
- USB-C Output:100W, fast charging
- Recharging Options:AC, solar panel, RV/car adapter
- Protection Features:Overcurrent, overheating, overcharging, overdischarge, overvoltage, short circuit protection
Our verdict“This model suits users who need substantial power capacity and multiple recharging options, but isn’t ideal for frequent air travelers seeking portability.”
EASYLONGER ES400 AIR CPAP Battery Backup, 148Wh One-Night Power Supply for ResMed, AirSense, AirCurve, AirMini, DreamStation – Travel, Camping, Emergency
The EASYLONGER ES400 AIR offers a reliable power source for a full night’s CPAP therapy, making it an excellent choice for short trips or camping. Compared to larger batteries like the ES720 PRO, this 148Wh unit is lighter and more portable, ideal for travelers who prioritize weight and ease of packing. It supports pass-through charging and has multiple recharge options, including AC, car, and solar, ensuring versatility in remote locations. Its limited capacity, however, makes it unsuitable for extended trips or use with humidifiers, which can reduce runtime. The absence of a heated tube support and additional cables may also be inconvenient for some users.
Pros:- Provides a full night’s CPAP power in a compact size
- Supports pass-through charging to prevent interruptions
- Multiple recharge options including AC, car, and solar
Cons:- Limited to about one night, not suitable for extended use
- Car charger and solar panel not included
Best for: Travelers or campers needing a compact, one-night power backup that is easy to carry and recharge on the go.
Not ideal for: Those planning longer trips or using heated humidifiers, as capacity may fall short and features are limited.
- Capacity:148Wh
- Compatible Devices:ResMed AirSense 10/11, AirCurve 10/11, AirMini, S9, Luna G3, DreamStation 1/2
- Recharge Time (AC):4-5 hours

Pilot-24 Lite 95Wh CPAP Battery Backup Power with S9 Cable, Portable, TSA & FAA Approved
The Pilot-24 Lite offers a lightweight, TSA and FAA-approved solution for powering CPAP machines during travel. Its 95Wh capacity makes it ideal for those who need just enough power for a single night or short trips, and its compact 1.3-pound design supports easy packing. The rapid 2-3 hour recharge time maximizes convenience, especially for last-minute trips. Unlike larger batteries such as the ES720 PRO or ES960, it doesn’t support multiple nights or larger devices, but its compliance with airline regulations makes it a preferred choice for frequent travelers. A notable limitation is that it requires a compatible power cord, and its capacity may not suffice for heavier setups or humidifier use.
Pros:- Lightweight and portable for travel
- TSA & FAA approved for airline use
- Rapid recharge time of 2-3 hours
- Supports charge of multiple devices via USB
Cons:- No included power adapter, needs compatible cord
- Limited to 95Wh, suitable only for short trips
Best for: Frequent flyers or travelers needing a TSA-approved, lightweight backup for a single night’s CPAP therapy.
Not ideal for: Users requiring longer runtime or using heated humidifiers, as capacity and features are limited.
- Capacity:95Wh
- Compatibility:ResMed S9, AirSense 10, AirMini
- Recharge Time:2-3 hours
- Approval:TSA & FAA
- Weight:1.3 lbs
Our verdict“This battery is ideal for travelers prioritizing portability and airline compliance over extended power support.”
CPAP Battery Backup Power Supply, 264Wh for Camping and Emergency Use
The 264Wh portable backup from this line provides over two nights of power, comparable to the larger ES720 PRO, but with more ports and wireless charging. Its compatibility across a broad range of CPAP models and included universal adapters make it highly versatile. Compared with the ES960, it offers similar capacity but with more ports, accommodating multiple devices simultaneously. Its support for wireless charging and multiple input options enhances outdoor usability, though it doesn’t support heated tubes and requires additional cables for some interfaces. The solar panel and car charger are sold separately, which could be a downside for those seeking an all-in-one solution.
Pros:- High-capacity 264Wh supports over 2 nights of use
- Universal adapter tips for broad device compatibility
- Multiple ports plus wireless charging
- Supports various recharging methods including solar
Cons:- Heated tube support is not available
- Additional cables and panels sold separately

- Charging Time:3-4 hours with 48W AC
- Ports:7 ports + wireless charging
- Battery Type:LiFePO4
- Cycle Life:up to 3000 cycles
Our verdict“This battery suits users who need a multi-port, versatile power supply for extended outdoor or emergency use, but not for airline travel.”
EASYLONGER ES960 CPAP Battery Backup 297.6Wh LiFePO4 for AirSense 11/10, AirCurve 10/11, AirMini, DreamStation/2
The ES960 offers a substantial 297.6Wh capacity, making it suitable for multiple nights and heavier setups, including those with humidifiers. Its long cycle lifespan of over 3000 charges and support for a wide range of CPAP models, including the latest ResMed and Philips devices, make it a durable, high-end option. Compared with smaller batteries like the Pilot-24 Lite or ES400, this unit is better suited for frequent travelers who need extended power without worrying about capacity limits. The larger size, however, means it exceeds TSA limits, restricting its use for airline travel. It also requires additional adapters or cables for some devices and doesn’t support heated tubes.
Pros:- Very high capacity supports multiple nights of use
- Supports a wide range of CPAP models and devices
- Long cycle life of over 3000 charges
- Multiple recharge options including USB-C and AC
Cons:- Exceeds TSA airline travel limits

- Recharge Time:6-8 hours (USB-C), 5-6 hours (AC), ≥100W solar panel (not included)
Our verdict“This battery is best for heavy-duty travel scenarios and frequent campers who value durability and long-term reliability over portability.”
EASYLONGER ES720 CPAP Battery Backup 266.4Wh Portable Power Supply for ResMed, Philips DreamStation, and More
The EASYLONGER ES720 stands out for its wide compatibility, supporting a broad range of CPAP models including ResMed, Philips DreamStation, and AirMini. Its 266.4Wh capacity offers enough power for multiple nights, and the multiple recharging options—AC, USB-C PD, solar, and car outlet—add to its convenience. Unlike smaller batteries like the EASYLONGER ES270, this model is better suited for longer trips or users who need to power more demanding devices, though it’s bulkier and heavier, which may impact portability. The inclusion of safety features like BMS protection and the pass-through charging feature make it a reliable choice for outdoor use. However, it doesn’t support heated tube heating for Luna G3, and it requires a voltage converter when connecting via cigarette lighter, which could be a drawback for some users.
Pros:- Supports a wide range of CPAP models and portable devices
- Multiple recharging options including solar and vehicle power
- Built-in safety features and pass-through charging for convenience
- Emergency LED SOS light for outdoor emergencies
Cons:- Heavy and bulky, limiting portability

Our verdict“This battery backup suits frequent travelers and outdoor users needing high capacity and versatility despite its size.”
EASYLONGER ES270 CPAP Battery for Air Travel and Camping
The EASYLONGER ES270 offers a compact, TSA and FAA-approved 99.9Wh capacity, making it ideal for those who prioritize airline compliance and portability. Its support for fast charging and wireless charging enhances convenience for short trips or camping. Compared with larger models like the ES720, this battery delivers fewer hours—generally up to 8—so it’s best suited for low-power or travel-friendly CPAPs. While the small size is a major advantage, it limits runtime for high-power machines or those with humidifiers active during use. The included cables and quick recharge time make it a solid choice for travelers, but users should be aware it’s not designed for extended multi-night power needs.
Pros:- Approved for air travel, TSA & FAA compliant
- Supports fast charging and wireless charging
- Compact and lightweight for easy carrying
- Includes multiple compatible cables
Cons:- Limited runtime for high-power or humidifier-equipped CPAPs

- Capacity:99.9Wh
- Dimensions:5.1×2.9×1.9 inches
- Power Output:PD 100W
- Recharge Time:2 hours
- Included Accessories:4 CPAP cables, 65W USB-C adapter, USB-C to C cable, user guide
- Supported Devices:Low-power CPAP machines
Our verdict“This pick is best for travelers seeking a lightweight, airline-compliant battery for occasional or short-term use.”
Zopec Explore 5700 Universal Travel CPAP Battery (Up to 3 Nights)
The Zopec Explore 5700 is tailored for travelers needing a longer power reserve, offering up to 3 nights of operation with most CPAP or BiPAP machines. Its universal compatibility with popular models like ResMed and Philips Respironics makes it a flexible choice for users who want a one-size-fits-all solution. The long battery life—often 7-8 hours with humidifier—and its lightweight, slim profile make it a standout for camping or multi-night trips. Unlike larger capacity batteries, it’s limited to about 3 nights, which should suit most travelers but not those with exceptionally high power demands. It’s also FAA/TSA compliant, simplifying air travel, though it lacks a heated tube and requires careful handling to maintain longevity.
Pros:- Universal compatibility with most CPAP/BiPAP machines
- Long battery life for multiple nights
- Compact, lightweight design
- FAA/TSA compliant for air travel
Cons:- No heated tube support included
- Limited to approximately 3 nights of use

Its support for a wide range of devices, including AirSense and DreamStation models, and multiple charging options—AC, USB-C, solar, and car—offer unmatched flexibility. Compared to smaller batteries like the ES270 or the Zopec Explore, this model provides significantly more runtime but at the expense of portability, making it less suitable for frequent air travelers who need ultra-light gear.

Choosing the right battery backup for your CPAP machine while traveling involves more than just capacity. Several factors influence how well a unit meets your needs, from size to compatibility. Assessing these carefully can save you from frustration and ensure your sleep quality remains uninterrupted during trips.Capacity and Runtime
Battery capacity, usually measured in watt-hours (Wh), directly impacts how long your CPAP can run without external power. Larger capacity batteries provide longer sleep times but tend to be heavier and less portable. Consider your typical sleep duration away from power sources and select a capacity that comfortably covers it, with some buffer for unexpected delays. Remember, a battery with too much capacity might be cumbersome, while one with too little may not last through the night.
Compatibility and Connectors
Not all batteries work with every CPAP model, so verifying compatibility is crucial. Look for units that specify support for your device’s voltage and connector type. Many batteries come with multiple cables or adapters, increasing their versatility. Choosing a model with broad compatibility helps avoid additional purchases or adapters, simplifying your travel setup and reducing the risk of incompatible gear during critical moments.
Size, Weight, and Portability
Lightweight, compact batteries are easier to carry through airports and on outdoor adventures. However, smaller units may sacrifice capacity. Consider your mode of travel—air, road, or camping—and choose a size that fits your comfort level without compromising enough power. Features like TSA approval and airline-friendly size specifications can streamline security checks and boarding processes.
Safety and Battery Chemistry
LiFePO4 (Lithium Iron Phosphate) batteries offer increased safety, longer lifespan, and more stable chemistry compared to traditional lithium-ion units. For frequent travelers or those venturing into remote areas, investing in a safer, more durable battery can be worthwhile. However, these tend to be more expensive, so weigh the safety benefits against your budget and travel frequency.
Additional Features and Accessories
Extras like multiple charging options (solar, AC, car), swappable cells, or built-in displays can enhance usability. Some units include USB ports or DC outlets for charging other devices, adding versatility to your pack. Consider whether these features align with your travel plans and if they justify any additional cost or complexity, especially if you need a simple, straightforward power backup.
Frequently Asked Questions
How do I know if a battery backup will work with my specific CPAP model?
Compatibility depends on voltage, connector type, and power requirements. Check the manufacturer’s specifications for your CPAP device, including voltage and connector details, then compare them with the battery’s output options. Many batteries list compatible models or include multiple adapters, ensuring a match. If in doubt, contact the manufacturer or seller to confirm compatibility before purchasing, avoiding the inconvenience of incompatible gear during travel.
Can I use a regular power bank for my CPAP machine during travel?
While some portable power banks can power a CPAP, they often lack the capacity, proper voltage, or connectors needed. Most regular power banks are designed for phones or small devices and won’t last through a full night or support the wattage required by CPAP units. Investing in a dedicated CPAP battery backup ensures reliable, consistent power and reduces the risk of device damage or insufficient runtime.
What’s the best battery capacity for a typical one-night trip?
A battery with around 90-150Wh generally covers a standard one-night sleep session for most CPAP models. Larger capacities provide extra buffer, useful if your trip involves multiple nights without access to power, but they come with increased weight and size. Consider your device’s power draw and sleep duration, then choose a unit that offers at least 20% more capacity than your estimated nightly use to ensure peace of mind.
Are lithium iron phosphate (LiFePO4) batteries worth the extra cost for travel?
LiFePO4 batteries are safer, more durable, and typically last longer than traditional lithium-ion units. For frequent travelers or those venturing into remote areas, these qualities can justify the higher price, offering peace of mind and fewer replacements over time. However, if your travel is occasional and cost-sensitive, a high-quality lithium-ion battery may suffice, but always check safety certifications and user reviews for reliability.
How do I ensure my battery backup is airline compliant?
Most airlines have restrictions on battery capacity and size, typically allowing units up to 100Wh without approval and up to 160Wh with airline permission. Always check your airline’s regulations before packing a battery backup. Keep the unit in your carry-on luggage, ensure it is properly labeled if required, and avoid packing damaged or swollen batteries. Opt for batteries clearly marked as TSA-approved or airline-friendly to streamline security checks.
Conclusion
For most travelers, the Pilot-24 Lite 95Wh offers an excellent balance of size, weight, and reliable power, making it the best overall pick. Those prioritizing extended run times and longer trips should consider larger capacity options like the BLUETTI X30 297Wh. Budget-conscious users or occasional travelers might find the EASYLONGER ES400 148Wh sufficient, while outdoor enthusiasts will appreciate the rugged design of the EnginStar 296Wh. If safety and longevity are key, a LiFePO4 model like the EASYLONGER ES960 makes sense. Ultimately, selecting the right backup depends on your travel style, device compatibility, and capacity needs, but this guide aims to make that choice clearer.
