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
