Advice Needed: Running AirSense 11 on Battery for 6 Nights at Le Mans

[PaulJ]

Hi everyone,
I’m heading to the 24 Hours of Le Mans this year and will be camping for 6 nights. I use a ResMed AirSense 11 with a P10 nasal mask, and I’m trying to work out the most reliable way to power it while I’m there.
A few questions I’d really appreciate advice on:
1. Pilot‑24 Lite battery• How well does it run the AirSense 11 overnight with humidifier/heated tube off?
• Is one battery enough if I can recharge it daily from the car?
• How long does it take to recharge from a 12V socket?

2. Charging at Le Mans• I know the campsites don’t have mains power — has anyone successfully charged a CPAP battery from their car during the day?
• Any tips for managing power over multiple nights?

3. Alternative setups• Has anyone used a different battery or a DC converter directly from the car with the AirSense 11?
• Any recommendations for UK rental options for CPAP batteries?

I’m just trying to make sure I can sleep properly during the trip without lugging around unnecessary gear.

Thanks in advance for any advice — especially from anyone who’s done Le Mans with a CPAP before.

Hello,

The battery should power the Airsense 11 for approximately 12 hours if the average pressure is 10 cm H2O and if humidity and tube temperature are disabled. However, depending on the pressure, it can change the time slightly.

The battery charges in 4-6 hours using the 12V Medistrom car charger. One battery should be enough if it's being charged daily.


If using a normal wall socket to charge using your CPAP power cable, then it would take 2-3 hours to charge.

The Medistrom car charger is designed to charge the Pilot-24 Lite battery using the car's 12V outlet. The car should be running while charging the battery, and the CPAP should never be connected to the battery while it's charging.

You can purchase a 12V DC cable here - https://www.intushealthcare.com/product/pilot-12-24-12v-dc-cable-car-charger/?gad_source=1&gad_campaignid=12413239882&gbraid=0A AAAABin7pFFKLJ1LpFombZ2m6aH02_iB&gclid=Cj0KCQjwz9_ QBhD_ARIsADnSCfCJJtnlwFn7dBwjEFX6b9IQeUV7hhFoeQRmI sIwEfAHeY9jWX0b0vEaAkL3EALw_wcB
