CPAP Batteries & Chargers

The AirSense 11 is a 24V device. Two choices: the Pilot-24 Lite (dedicated model, higher capacity) or the Pilot Flex (dual voltage, more compact). The Pilot-24 Lite is generally the best compromise for home or regular travel. The Pilot Flex is perfect for frequent flyers.

Medistrom states 1 to 2 nights for the Pilot-24 Lite at average pressure with the humidifier and heated tubing switched off. As soon as you turn the heating on, runtime drops sharply: heating the air and the tube draws far more than the blower itself. For two safe nights, plan two batteries or switch heated humidification off.

Yes. Medistrom Pilot batteries are FAA and IATA compliant for cabin baggage. They are below the 100 Wh threshold accepted by default by most airlines. Important: always cabin, never hold (safety rule). Keep the certification with you in case airport security asks.

With a 12V/24V cigarette adapter specific to your CPAP model. The converter transforms the car's 12V into 24V (or 12V depending on your CPAP) compatible with your device. Ideal for camper, road trips, cruises (boats often have 12V like cars). Important: keep the engine running, otherwise you drain the car battery in a few hours.

First, check three things: (1) the wall socket works, test it with a lamp; (2) the cable is not damaged; (3) the connector on the CPAP side is clean and fully pushed in. If all three are fine and the device will not switch on, the power supply is dead. Order a replacement 65 W power supply that matches your model. Never use another brand's power supply: the voltage and the connector are proprietary, and the wrong supply can destroy the device.

A Medistrom battery is the most durable purchase in this category: the manufacturer states over 500 full charge cycles. If you only use it when travelling, a few times a year, it will last you far longer than if you cycle it every night. Current prices are on each product page above.

Worth it if you live: (1) in a rural area with frequent outages, (2) in a region where weather regularly causes power cuts, (3) if your apnea is severe and a CPAP-less night significantly impacts your health (drowsiness, hypertension). Otherwise, rare once-a-year outages = not essential. The Medistrom Pilot can be left fully charged as a dedicated CPAP UPS.

No. The 12V/24V converter is specific to the CPAP model because the power connector differs between manufacturers (ResMed, Philips, Löwenstein each have their own proprietary plug). Check your model carefully before ordering. On the car side, the other end is a universal standard cigarette plug.
