Battery Power Rules!

I could not run mine on the 12 volt because it was lowering the pressure. I just got a 12 volt inverter and that took care of the issue. Two 12 volt deep cycles wired parallel would keep me breathing for a week of camping. No heated humidifier, but it was no big deal.

What cpap do you have ? Edsel.. Actually, 12 volts is misleading. Its at about 50% at 12 volts. 13 volts is fully charged. If you check the voltage of your car while running it is about 13.5 -14 volts. Charging as high as 16 . My cpap has 13 volts printed on it. If your cpap is droping pressure your battery is really weak or really small . A normal auto battery should have no problem running a modern cpap for 1 night. The drain will be barely noticable with a voltmeter.

An inverter will draw more power without a load than most cpaps use . That is if the cpap was built in the last few years. Can't say for the classics. They may not be as efficient.

Thank you for all of the replies! I slept in the back of my Tahoe with the CPAP machine going all night. The Tahoe started right up in the morning. I did not hook up my heated humidifier or the heated hose.

FYI ...Aeiomed will also eventually be coming out with a car battery charger for their battery pack for long camping trips.

The Aeiomed car power adapter (plugs into your lighter slot) that recharges the Aura battery is said to be available in mid to late august. wonder if that will happen?

Hi, I'm a newbie so please bear with me.

I travel in countries with unreliable electricity outages, some brief, and others longer.

Can anyone recommend a travel battery pack that can power my S8 through the night and and be recharged via the mains during the day (I do not take the humidifier on these brief trips).

I have a Resmed S8 2.5A CPAP and need an 8 hr night.

I see the Respironics Battery Pack at around USD 230, and wonder if it is compatible with the Resmed.

Thanks
