EASYLONGER ES960 CPAP Battery Backup
The EASYLONGER ES960 is a high-capacity CPAP battery offering 297.6Wh, designed to power a wide range of machines including AirSense 11, AirCurve 11, AirSense 10, AirMini, and Philips DreamStation families. It ships with four DC cables for direct compatibility with many models, and it supports off-grid operation with the humidifier and heated tube off, extending run times during outages or camping trips. While maximizing runtime, note that using additional features reduces overall duration. A flexible 24V output option and compatible DC cabling expand device compatibility beyond the listed units.
Practical use notes: it’s suitable for several nights of therapy when unplugged, especially if you turn off heat/humidification. The ES960 is a strong choice for travelers and campers who need reliable backup power without frequent recharging. It’s also compatible with a broad set of 24V PAP devices using the proper DC cable, though some configurations may require separate adapters not included in the box.
Medistrom Pilot-24 Lite Bundled with Cables
The Pilot-24 Lite is a compact 95Wh CPAP backup designed to keep you asleep through outages. It’s compatible with a broad range of devices, including ResMed S9, AirSense 10, and AirMini, with cables sold separately to support AirSense 11, S9, prismaSMART, Luna, and DreamStation variants. The unit offers a simple, portable power solution that recharges quickly—typically in 2-3 hours—so you can rely on quick readiness for travel or emergencies. Its aluminum case and quality cells emphasize durability for repeated use.
On standby for long trips or camping, Pilot-24 Lite can function as a standalone battery or a backup supply, depending on your device. While it does not power every CPAP model via an integrated AC outlet, it remains a practical choice for travelers seeking a light, TSA-friendly option with dependable performance and straightforward setup.
Renogy 72000mAh 266Wh Power Bank CPAP Battery
The Renogy 72000mAh battery pack delivers 266Wh of capacity and features USB-C PD outputs, including a dedicated 60W port for laptops and a high-speed 27W port for mobile devices. It supports up to five devices simultaneously with intelligent battery management to optimize efficiency. Important caveats: this unit is intended for off-grid CPAP use via a DC output—no built-in AC plug—and airplane travel restrictions apply to certain configurations. A CPAP adapter is required for direct CPAP connection, and heater/humidifier usage may reduce runtime.
Designed for off-grid camping or extended outages, this pack emphasizes versatility for travelers who need more than basic USB charging. The 150W max DC port supports specific CPAP models, including DreamStation and AirSense variants, when paired with the appropriate CPAP adapter cable. It’s a strong choice for users who want robust capacity and flexible charging options, provided they manage wiring correctly for their device.
EASYLONGER ES720 CPAP Battery Backup
The ES720 offers 266.4Wh of power, designed to run 24V PAP devices, including AirSense and DreamStation models. It includes multiple outputs and a pass-through charging option, enabling continued CPAP operation while the battery recharges. The device supports 12V/16.5V/20V/24V DC output settings to match different CPAP operating voltages, which minimizes the need for additional adapters. This flexibility makes it suitable for travelers who require dependable backup power with straightforward, direct device compatibility.
With two DC cables in the box and compatibility with a wide set of devices, the ES720 balances runtime, portability, and ease of use. It is a practical option for those who want a compact backup that still delivers substantial runtime without sacrificing charging flexibility during trips or outages.
Portable Outlet PO-160UPSv2 159Wh UPS CPAP Battery
The Portable Outlet PO-160UPSv2 is a versatile 159Wh UPS battery designed to power CPAP machines and other essential devices during outages. It functions as an uninterruptible power supply for CPAP, BiPAP, APAP, and AutoPAP devices across North America, reducing the need for adapters. It also supports USB charging for laptops, tablets, and phones, making it a practical all-in-one solution for home backups and travel. The unit’s raised chassis and enhanced circuitry help it run cooler during operation, contributing to safer long-term use.
Aside from CPAP, this UPS setup is valuable for households that want a reliable secondary power source for essential devices. It’s marketed with a focus on reliability and ease of use, including a 1-year warranty. The PO-160UPSv2 is particularly appealing for emergency preparedness and travel where power continuity matters for sleep therapy and other daily needs.
Buying Guide: Key Purchase Considerations
- Capacity and run time: Higher Wh ratings offer longer runtimes, particularly if you plan to use a heated humidifier or heated tubing. Consider how many nights you need backup power and whether you’ll turn off auxiliary features to extend runtime.
- Device compatibility: Check your CPAP model and the included cables. Some packs require adapter cables or separate cables for certain machines. If you travel often, verify whether a DC output or USB-C PD port aligns with your device requirements.
- Weight and portability: For travel or camping, lighter units with favorable power-to-weight ratios are preferable. Consider whether you need a compact unit for airline restrictions and easy packing.
- Charging options and pass-through: Look for models that support pass-through charging to ensure your CPAP continues to run while the battery itself recharges. This is especially useful during power outages when you need uninterrupted therapy.
- Safety and durability: Aluminum housings and high-quality cells improve durability for repeated use. Verify any safety certifications and the warranty terms to gauge long-term reliability.
- Expansion and modular setups: Some systems allow chaining or dual-battery configurations to extend run time during extended outages. This can be useful for longer trips or severe weather events.
- Regulatory considerations: Some batteries may be restricted on airplanes. Review airline policies for battery size and watt-hour limits to ensure compliant travel planning.
- User friendliness: Quick setup, intuitive indicators, and easy recharging times can reduce frustration during stressful travel or outages. Consider models with clear status indicators and simple cable management.
When selecting a CPAP backup battery, balance capacity with portability and model compatibility. For frequent travelers, smaller 95Wh–159Wh packs paired with the right cables can offer practical daily reliability, while higher-capacity options around 266–298Wh suit multi-night outages and camping with careful power management. Always confirm compatibility with your exact CPAP model and consider whether you want additional USB charging for devices beyond the CPAP.
