Question 1

Can I run a CPAP without any battery at all?

Accepted Answer

Yes, at powered sites. Most Australian holiday parks and a reasonable number of state park sites have powered options. For unpowered camping you need a dedicated station

Question 2

My machine only has a 240V plug. Can I still use a DC cable?

Accepted Answer

Most modern CPAP machines from ResMed (AirSense 10/11), Philips (DreamStation 2), and Fisher & Paykel (SleepStyle) have a separate DC input port in addition to the mains plug. Check your machine's manual or the label on the bottom. If yours genuinely doesn't have a DC port, you'll need an inverter, which makes the settings section above even more critical.

Question 3

Will running a CPAP void my power station warranty?

Accepted Answer

No. CPAP machines are low-draw, consistent loads and most manufacturers explicitly list medical device use as a supported application.

Question 4

We both use CPAPs. Can we run off the same station?

Accepted Answer

Yes, if the station is 1000Wh or larger and you're using DC cables with humidifiers off. With both machines drawing 8–10W each, a 1000Wh station will cover 4–5 nights comfortably. Don't try this on a 500Wh station.

Question 5

Does altitude affect the machine?

Accepted Answer

Pressure settings may need adjustment above around 2,000m. Relevant if you're camping in alpine Victoria or NZ high country. Check with your sleep physician before a high-altitude trip.

Question 6

What's the minimum viable setup for one night?

Accepted Answer

A 300Wh station and a DC cable with the humidifier off. That covers a single machine for one or two nights without stress.
