EASYLONGER ES960 Backup Power Supply
The EASYLONGER ES960 is a high-capacity CPAP battery backup designed for extended outages and camping scenarios. It provides 297.6Wh of stored energy with four included CPAP DC cables, enabling compatibility with ResMed S9, AirSense 10/11, AirCurve 10/11, AirMini, Philips DreamStation, and DreamStation 2 units. Users should note that heated tubing and humidifier use will reduce run time. The battery supports flexible output via a 24V setting and can power other devices with compatible DC connections when configured appropriately. This model is positioned for airline-conscious travelers seeking substantial reserve power.
Key considerations:
- Run-time depends on whether the humidifier and heated tube are used.
- Compatibility spans major CPAP brands but check the exact connector type for your device.
- 4 DC cables simplify setup but separate cables may be required for some machines.
- Compact for its capacity but remains heavier than travel-focused models.
Medistrom Pilot-24 Lite with Cables
The Pilot-24 Lite bundles a compact 95Wh CPAP backup with essential cables, offering a portable solution for camping or travel. It emphasizes uninterrupted sleep by providing a reliable power source for numerous 24V PAP devices, ensuring therapy continuity during outages. The design features quick setup and a rapid recharge, typically 2–3 hours, supporting on-the-go charging for CPAP devices when main power is unavailable. The aluminum chassis and high-grade cells contribute to a durable build suitable for repeated use. Some users may prefer higher capacity for longer outages, but this unit shines in portability and ease of use.
Key considerations:
- Ideal for travel and short outages due to its lighter weight and smaller footprint.
- Full recharge time is relatively quick, minimizing downtime between uses.
- Aluminum construction enhances durability and longevity.
- May require a larger unit for extended, multi-night outages with humidifier support.
Renogy 72Ah/266Wh Power Bank
The Renogy 72000mAh power bank provides a substantial 266Wh capacity and features 60W PD charging and 150W max output for CPAP off-grid use, making it suitable for certain DreamStation and AirSense models. It uses a 12V/15A cigarette port, allowing CPAP connections via a dedicated CD port rather than an AC plug. This model excels for users who prioritize multi-device charging via USB-C PD and a strong DC output for select CPAP setups. Note that it does not include an AC adapter, and compatibility depends on the CPAP model and required adapter cables.
Key considerations:
- High-capacity power bank with strong USB-C PD ports for laptops and devices.
- Configure CPAP output via supported DC connections; no built-in AC outlet.
- Best for users comfortable with external adapters to power their specific CPAP model.
- Be mindful of airline restrictions on minute-by-minute use and carry-on guidelines for larger batteries.
EASYLONGER ES720 Backup Power Supply
The EASYLONGER ES720 offers a mid-range 266.4Wh capacity with flexible DC output options, including a 12V cigarette lighter port. This battery is designed to power CPAP machines directly via the DC port, and it supports 24V CPAP outputs with appropriate cables. Users can achieve extended run times by turning off heaters or humidifiers when needed. The ES720 is a practical choice for campers and travelers who want a balance between weight, capacity, and versatility, especially for ResMed and Philips DreamStation models.
Key considerations:
- Versatile DC output configuration suitable for many CPAP setups.
- Run time varies with heater/humidifier usage; plan accordingly for longer trips.
- Consider purchasing compatible cables to ensure seamless CPAP connections.
- Relatively compact for its capacity, aiding portability.
Portable Outlet PO-160UPSv2 CPAP UPS
The Portable Outlet PO-160UPSv2 is a 159Wh UPS that powers CPAP devices and other essential electronics during outages. It’s marketed as more than a CPAP battery, capable of supporting laptops, tablets, phones, and other USB devices, making it a versatile backup for home and travel. The unit emphasizes pass-through charging and a lower-profile footprint for travel readiness. It’s compatible with a broad range of PAP devices, including CPAPs from Philips and ResMed, and it supports daisy-chaining to extend runtime in emergencies.
Key considerations:
- UPS functionality adds resilience for multiple devices beyond CPAP.
- 8–18 hours of runtime depending on device load and configuration; recommended for home-based outages.
- Designed with heat management and a raised chassis for cooler operation.
- Consider compatibility with your CPAP model and any required connectors.
Buying Guide: Key Purchase Considerations And Comparisons
Choosing the right CPAP backup battery depends on your typical outage duration, travel needs, and device compatibility. Consider these core factors to compare models effectively:
- Capacity and run time: Higher watt-hour (Wh) ratings generally translate to longer run times, especially if you plan to operate humidifiers or heated tubes. Balance capacity with weight for travel needs.
- CPAP compatibility: Check whether the battery outputs match your CPAP’s voltage and connector type. Some units require specific cables or adapters; others offer direct DC ports or 12V cigarette-lighter connections.
- Output options: Look for multiple DC cables, USB ports, and, if needed, an AC pass-through. Pass-through charging lets you power the CPAP while charging the battery, which is convenient for long trips.
- Weight and form factor: Heavier batteries deliver more capacity, but portability matters for air travel and outdoor use. Consider a balance that fits your carry-on or camping gear.
- Recharge time: Shorter recharge times minimize downtime between uses. Compact models may recharge faster but offer less total runtime.
- Airline and travel restrictions: Airlines commonly limit Li-ion battery size per passenger. If you travel often, prioritize models around 100–160Wh to minimize restrictions, or split power needs across two smaller packs if allowed.
- Durability and warranty: A rugged build with a solid warranty reduces long-term risk, especially for outdoor use. Aluminum casings and sturdy construction are advantageous.
- Accessories and cables: Confirm included cables and whether additional cables are required for your CPAP model. Cables sold separately may impact total cost and setup complexity.
- Noise and heat management: Durable chassis and effective heat dissipation help maintain battery life and performance during repeated cycles.
- Multi-device versatility: If you need to charge other devices, select models with USB-C PD, multiple USB ports, or AC outlets for broader utility.
In summary, the best choice depends on your unique scenario. For long outages or camping with humidification, a larger capacity unit like the EASYLONGER ES960 can provide multiple nights of therapy. For travelers seeking light weight and TSA-friendly travel, the Medistrom Pilot-24 Lite Bundled or Pilot-24 Lite itself offers solid performance with straightforward operation. If you require a balanced mix of capacity and portability with flexible USB-C charging, Renogy and ES720 provide strong options. For a versatile UPS that powers CPAP and other devices, the Portable Outlet PO-160UPSv2 delivers broad compatibility and pass-through charging.
