Does the AirMini CPAP have a battery?

No — the ResMed AirMini does not include a built-in battery, but you can power it off-grid with an external battery or a DC converter.

The ResMed AirMini is the world's smallest travel CPAP machine, and to keep it that compact, ResMed designed it without an internal battery. That doesn't mean you're tied to a wall socket though — there are three purpose-built options for running your AirMini away from mains power, and each suits a different style of travel.

How to power your AirMini without mains

1. Medistrom Pilot-24 Lite portable battery

The Medistrom Pilot-24 Lite is the long-standing favourite battery solution for the AirMini. It's a compact lithium-ion travel battery that delivers up to 16 hours of run time on an average pressure setting — typically 1 to 2 nights of therapy on a single charge. It's FAA-approved for in-flight use and a popular choice for camping, road trips, and as a home backup during blackouts.

To run the AirMini from the Pilot-24 Lite, you'll need a specific AirMini output cable. If you don't already own one, our Pilot 24 Lite Battery with Charging Cables kit bundles the battery, an AC charger, a car charger, and the AirMini-compatible cables together.

2. Medistrom Pilot Flex (newer dual-voltage battery)

The Medistrom Pilot Flex is the newest generation Medistrom battery and offers some real advantages for AirMini users. It's the smallest CPAP battery on the market — under 500 grams — and supports both 12V and 24V machines, which means the same battery will power your AirMini today and a future AirSense 10 or AirSense 11 if you ever add a bedside CPAP. The AirMini connection cable is included in the box, so there's no separate cable to buy.

Other practical upgrades over the Pilot-24 Lite include USB-C charging (handy when you're already travelling with USB-C gear), a 98Wh capacity that sits just under the 100Wh airline lithium-battery limit for hassle-free flying, and the ability to chain multiple Pilot Flex batteries together if you need more than two nights of off-grid run time.

3. ResMed AirMini DC/DC Converter (65W) — for vehicle use

If you're powering the AirMini from a vehicle, the AirMini DC/DC Converter (65W) plugs into a 12V or 24V cigarette lighter socket, letting you run the device directly from your car, caravan, boat, or 4WD electrical system. This is the right choice for road trips and overnight stays where a vehicle is your power source — but it's not a solution for use on a flight.

Common questions about AirMini battery power

How long will a Medistrom battery run the AirMini?

Both the Pilot-24 Lite and the Pilot Flex are rated for up to 16 hours of CPAP run time on an average pressure setting — usually 1 to 2 nights of therapy from a single charge on the AirMini. Real-world run time depends on your prescribed pressure, ambient temperature, and battery age. Lower pressures stretch the battery further; higher pressures will shorten it.

Can I take the AirMini battery on a plane?

Yes. Both the Pilot-24 Lite and the Pilot Flex are lithium-ion batteries within standard airline carry-on watt-hour limits — the Pilot Flex sits at 98Wh, just under the 100Wh threshold most airlines apply. The AirMini itself is recognised as a medical device that typically doesn't count toward your carry-on allowance. We always recommend checking your specific airline's policy on lithium batteries and medical devices before you fly.

Can I run the AirMini from my car overnight?

Yes — using the AirMini DC/DC Converter (65W) plugged into a 12V or 24V cigarette lighter socket. For overnight use the engine will be off, so you'll be drawing from the vehicle battery. The AirMini draws around 20W, so plan that load against your battery's capacity — and if you camp regularly, consider a deep-cycle auxiliary battery setup.

Which option is right for me?

If you want the established, proven AirMini battery and you're focused on flights and camping, choose the Pilot-24 Lite. If you want the lightest, newest battery with higher cpapacity and USB-C charging and future compatibility with a bedside CPAP, choose the Pilot Flex. If you travel by car, caravan or boat and want to power the AirMini straight from the vehicle, choose the AirMini DC/DC Converter. Some users keep both a battery and a DC converter on hand for full flexibility.
