Several ResMed BiPAP/BiLevel devices have a 24 volt DC power input which enable them to run from a 12 volt or 24 volt battery using this ResMed converter. The ResMed's DC Converter allows you to operate a VPAP® system from 12V or 24V DC power sources like the cigarette style sockets found in most cars, boats and other vehicles. This is the only cords that should be used with ResMed VPAP® systems.
