CPAP Battery Guide 2025 - Medistrom Pilot 24 Lite

CPAP Battery - Complete Guide for Cord-Free Therapy

Going camping, travelling by plane, or staying somewhere without reliable electricity? A CPAP battery lets you continue your sleep apnea therapy without depending on a mains outlet. This guide covers everything you need to know: how to choose the right battery, maximise its runtime, and travel with confidence.

VivaRespire sells the Medistrom Pilot 24 Lite, the reference CPAP battery for AirSense 10 and AirSense 11 devices. Order directly from our shop with fast European delivery.

Why Use an External Battery for Your CPAP?

A CPAP machine normally runs on mains power (230 V in Europe). The moment you leave home, power supply becomes a challenge:

  • Camping and outdoor trips: no electrical outlet, so a portable battery or solar panel is essential.
  • Flights: in-seat power is unreliable or incompatible. An FAA-approved battery lets you sleep during the flight.
  • Power outages: a charged battery guarantees at least one full night of therapy.
  • Van life or mountain cabins: solar installations are not always compatible with standard CPAP power bricks.

Skipping even one night of CPAP therapy can bring apnea events back, increase daytime fatigue and raise cardiovascular risk. A backup battery is a health investment.

Medistrom Pilot 24 Lite: The Reference Battery for AirSense 10 & 11

The Medistrom Pilot 24 Lite is natively compatible with the most widely used ResMed devices: AirSense 10, AirSense 11 AutoSet and AirSense 11 Elite.

Technical Specifications

  • Capacity: 97 Wh (below the 100 Wh airline threshold - no special authorisation needed in most cases)
  • Weight: ~720 g - lightweight for travel
  • Output voltage: 24 V DC, compatible with ResMed power connector
  • Charges via USB-C Power Delivery or included AC adapter
  • Integrated LED charge indicator
  • CE certified and IATA / FAA compliant for carry-on luggage

Estimated Runtime by Configuration

Configuration Estimated runtime (AirSense 11)
Pressure only, no humidifier, no Wi-Fi 1.5 to 2 nights (~13-16 h)
Heated tube only ~7-9 h (1 night)
HumidAir 11 humidifier (medium setting) ~6-8 h
Humidifier + heated tube ~5-6 h
Battery life tip: Disable Wi-Fi on the AirSense 11 (Settings > Connectivity) and reduce or turn off humidifier heating. These two adjustments can effectively double your runtime.

Flying with a CPAP Battery

The Medistrom Pilot 24 Lite at 97 Wh stays below the 100 Wh threshold set by most airlines, so it can be carried on board without prior authorisation.

  • Carry-on only: lithium batteries are prohibited in checked baggage.
  • Up to 100 Wh without declaration: between 100-160 Wh requires airline approval.
  • Maximum two batteries per passenger (IATA rule).
  • Keep the datasheet showing Wh capacity in your bag.
  • Check with your airline beforehand if you are unsure - rules vary slightly between carriers.

CPAP Battery for Camping

  • Charge fully before you leave - a full charge takes about 3-4 hours.
  • Pair with a solar panel: a 60-100 W USB-C panel can recharge the Pilot 24 Lite during the day.
  • Turn off the humidifier: outdoor air is often moist enough. Save battery power for pressure delivery.
  • Use a lightweight nasal pillow mask like the AirFit P10 to reduce leaks and lower power demand.

Battery Care and Lifespan

  • Avoid deep discharging - do not go below 10-15% charge.
  • Store at 50% charge in a cool, dry place if not used for several weeks.
  • Avoid extreme temperatures (no direct sunlight, no hot car).
  • Recharge at least once a month during periods of inactivity.

Device Compatibility

The Medistrom Pilot 24 Lite is designed for ResMed 24 V DC devices:

It is not compatible with the AirMini (which has its own dedicated battery) or the DreamStation 2 (which requires Philips Respironics accessories).
