Why CPAP battery compatibility matters
CPAP battery compatibility is the match between your machine's voltage, connector type, and a battery's output. Plugging the wrong voltage into your CPAP can damage the machine or simply not power it. As of 2026, different manufacturers still use different connectors (barrel, proprietary 3-pin, USB-C) and voltages (12V or 24V), so there is no single battery that works out of the box with every machine.
The bottom line: always verify three things before buying — voltage, connector shape, and minimum wattage. This CPAP battery compatibility chart maps out exactly what works with every major CPAP and BiPAP model sold in 2026, including newer options like USB-C PD power banks for compatible machines.
ResMed machines
ResMed AirSense 11
The AirSense 11 is the most battery-friendly CPAP on the market because it supports USB-C Power Delivery (65W+). This means almost any modern USB-C PD battery bank can power it — no proprietary cables needed. For a full breakdown of tested options, see our best battery for ResMed AirSense 11 guide.
- Input: 24V DC or USB-C PD (65W minimum)
- DC connector: Barrel connector or USB-C
- Power draw: 7-53W depending on pressure and humidifier settings
- Compatible batteries: Any 65W+ USB-C PD power bank, Medistrom Pilot-24 Lite, Zopec Explore Mini, most power stations via AC
ResMed AirSense 10
The AirSense 10 uses a proprietary 24V DC connector. You need a battery that either outputs 24V DC with the correct cable, or an AC power station with the stock wall charger.
- Input: 24V DC
- DC connector: 3-pin proprietary
- Power draw: 7-53W depending on pressure and humidifier settings
- Compatible batteries: Medistrom Pilot-24 Lite, Freedom V², Zopec Explore Mini, ResMed Power Station II
- Cable needed: ResMed DC/DC converter (sold separately) or battery-specific cable
For tested runtimes and buying advice, see our best battery for ResMed AirSense 10 guide.
ResMed AirMini
The travel-focused AirMini also runs on 24V but uses a smaller connector. Purpose-built CPAP batteries like the Pilot-24 Lite and Zopec Explore Mini include the compatible cable. See our best battery for ResMed AirMini guide for detailed comparisons.
- Input: 24V DC
- DC connector: Micro USB-shaped proprietary
- Power draw: 7-27W (no heated humidifier)
- Compatible batteries: Medistrom Pilot-24 Lite (with AirMini cable), Zopec Explore Mini, AC power stations
ResMed AirCurve (BiPAP)
The AirCurve series covers ResMed's bilevel (BiPAP) machines, including the AirCurve 10 and AirCurve 11. These draw more power than standard CPAPs — typically 30-70W — so battery capacity matters more. They share the same 24V DC input and connector types as their AirSense counterparts. See our best battery for ResMed AirCurve guide for tested runtimes and recommendations.
- Input: 24V DC (AirCurve 10: 3-pin proprietary; AirCurve 11: barrel or USB-C PD)
- Power draw: 30-70W depending on pressure differential and humidifier settings
- Compatible batteries: Medistrom Pilot-24 Lite, Zopec Explore Mini, Freedom V², AC power stations
- Key consideration: Higher wattage means shorter runtime — size your battery for at least 400 Wh if using heated humidification
Philips machines
Philips DreamStation 2
The DreamStation 2 runs on 12V DC, which opens up more battery options since 12V is the most common portable battery voltage. For tested options, see our best battery for DreamStation 2 guide.
- Input: 12V DC
- DC connector: Barrel connector (5.5mm x 2.5mm)
- Power draw: 5-45W depending on settings
- Compatible batteries: Most 12V batteries with correct barrel cable, Zopec Explore Mini (with DreamStation cable kit), Jackery/EcoFlow/Bluetti via AC
- Cable needed: 12V DC cable with 5.5 × 2.5mm barrel connector
Philips DreamStation (original)
The original DreamStation also uses 12V DC power with a similar barrel connector.
- Input: 12V DC
- DC connector: Barrel connector
- Compatible batteries: Same as DreamStation 2
Other brands
Fisher & Paykel SleepStyle
- Input: 24V DC
- DC connector: Barrel connector
- Compatible batteries: 24V DC batteries with correct cable, AC power stations
3B Medical Luna II
- Input: 12V DC
- DC connector: Barrel connector
- Compatible batteries: 12V DC batteries, AC power stations
Resvent iBreeze
The Resvent iBreeze is gaining popularity in 2026 as a budget-friendly CPAP alternative. It runs on 24V DC with a barrel-style connector. A 12V-to-24V DC converter cable is available from third-party sellers for running it from car batteries or 12V power stations.
- Input: 24V DC
- DC connector: Barrel connector (proprietary sizing)
- Power draw: 8-50W depending on model and settings
- Compatible batteries: Zopec Explore Mini (with iBreeze cable kit), 24V DC batteries with correct cable, AC power stations
- Cable needed: Resvent-specific DC cable or Zopec iBreeze cable kit
DeVilbiss IntelliPAP
- Input: 12V DC
- DC connector: Barrel connector
- Compatible batteries: 12V DC batteries, cigarette lighter adapter available
Multi-voltage batteries: the new universal option
A newer category of CPAP batteries solves the compatibility problem with automatic voltage detection. The Zopec Explore Mini, for example, uses patented multi-voltage technology to automatically output 12V, 19V, or 24V depending on the connected device. It ships with cables for ResMed AirSense 10, AirSense 11, and AirMini, with optional cable kits for DreamStation, Luna, Resvent iBreeze, and other brands.
For 2026, Zopec also offers the Explore Voyage — a 150 Wh travel battery (2.0 lbs) with USB-C PD 45W fast charging and a 100W AC outlet. It powers most CPAPs for 1.5-2 nights without heated humidification and is FAA compliant for air travel.

The universal fallback: AC power stations
If your CPAP model isn't listed or you want a no-brainer solution, any portable power station with a pure sine wave AC outlet will work. Just plug in your stock CPAP wall charger. The Goal Zero for CPAP is a popular choice for camping and overlanding.
Downsides: 10-15% energy loss from DC-to-AC-to-DC conversion, and the power station's fan may add noise. But it works with every CPAP on the market. See our battery sizing guide to account for this loss, and our CPAP power consumption guide for exact wattage numbers by machine.

Dedicated CPAP batteries worth considering
Purpose-built CPAP batteries skip the AC conversion entirely, connecting via DC for maximum efficiency and zero fan noise. For in-depth reviews, see our Medistrom Pilot-24 review and Freedom V2 CPAP battery review. These are the top options ranked by compatibility breadth:
If you use a BiPAP machine that draws more power, see our BiPAP battery backup guide for higher-capacity options. You may also need a DC power adapter to connect your machine directly.
What about BiPAP machines?
BiPAP machines typically draw 30-90W — roughly double what a standard CPAP pulls. The same compatibility rules apply: match the voltage and connector, then size the battery for the higher wattage. Most BiPAP users need 400+ Wh power stations for a full night. Our BiPAP battery backup guide covers the best options, and our CPAP battery sizing guide shows you how to calculate exact capacity needs.
What to do next
- Find your CPAP model in the compatibility table above and note the voltage and connector type
- Choose between a purpose-built DC battery (best efficiency) or an AC power station (universal compatibility)
- Use our CPAP battery sizing guide to calculate the exact Wh capacity you need
- Check our machine-specific guides for tested runtimes: AirSense 11, AirSense 10, AirCurve, DreamStation 2, or AirMini
