12 Volt Battery Power

There are 2 methods for powering a CPAP machine from a battery. Many CPAP machines have a connection for you to plug in DC power directly from a battery or car accessory outlet. Alternatively you can use a DC to AC converter to supply normal household voltage to your CPAP machine. In the following sections we will go into more depth about both methods as well as talk about the pros and cons for both.

Direct DC Power

This is the simplest method. It involves simply connecting a cable from a big enough 12 volt battery directly to the DC IN port on your CPAP machine. Most machines have a DC IN port but there are some exceptions. There is a major caveat though. There is only one heated humidifier that will run on DC power and it is machine specific (Respironics M-series, see below). The humidifier will still work for passover humidification though and this is often times enough, especially if you're only going a couple of nights.

Pros
The simplest method
The most efficient use of your precious battery power
No other devices are needed besides your CPAP machine, power cable, and battery. (except for ResMed machines, see below)

Cons
You can only use passover humidification or no humidification (except with some Respironics humidifiers, see below)
