VPAP Auto

Battery Guide

™

Indoors, outdoors or in transit—your
VPAP Auto can give you effective
therapy wherever you are.

Some simple accessories, used with a
battery or an uninterruptible power
supply (UPS), can help you use your
VPAP Auto even where mains
electricity is unavailable or unreliable.

What do I need?

Precisely what setup you require depends on
where you intend using your VPAP Auto and
whether you use a heated humidifier. The diagram
below shows the various options.

Using a battery with VPAP Auto

Inverter

An inverter adapts the 12/24V direct current (DC)
supplied by the battery into 110/240V alternating
current (AC) that powers your VPAP Auto.

Uninterruptible Power Supply (UPS)

A UPS consists of an inverter, a battery and a
battery charger. It is designed to supply power
automatically in the event of power loss.

Consider a UPS in situations where the AC
power supply (standard mains electricity) is
intermittent or unreliable.

Converter

The VPAP Auto has a 24V DC power socket which
allows the connection of a 12V or 24V DC power
supply (ie, battery) using the ResMed
DC-12 Converter.

Converters are more efficient than inverters and
ResMed recommends that you use the DC-12
Converter if you are using a VPAP Auto
without a humidifier. The HumidAire 3i will not be
heated unless you use an inverter or UPS.

Battery

ResMed recommends using either a 12V or 24V
deep-cycle battery. The battery capacity that you
will require depends on your system’s power
consumption (see Table B). You will need a
charger for your battery.

Can I use my humidifier with battery
power?

Yes (Note: Only the HumidAire 3i integrated
heated humidifier is compatible with the VPAP
Auto). You will require a larger capacity battery
