    Product Overview

    Manufactured by Battery Power Solutions.

    Product Features

    The 150W Modified Sine Wave Inverter for Portable Outlet & Freedom CPAP Battery Packs converts DC power to AC power. It allows you to charge the Portable Outlet from a DC source, as well as the Freedom Travel Battery.


    • Updated Design
    • Converts DC to AC
    • Provides Power for AC Only Devices
    • Can Charge the Portable Outlet from DC
    • USB Charging Port

    Updated Design

    The sine wave inverter for the Portable Outlet & Freedom travel battery packs has been updated to feature 2 USB ports and a 3 prong AC power outlet. The shape of the inverter has been redesigned to achieve the height and width needed for a 3 prong outlet. The taller, yet thinner unit houses an exposed outlet for easy accessibility. Any 2 prong or 3 prong connection can be used with this unit.

    Converts DC to AC

    The inverter can be used to power a device which requires AC power by plugging the device's power cord into the inverter. Convert the power by locating the 3 prong outlet found at the end of the inverter.

    Provides Power for AC Only Devices

    The inverter can be plugged into the C-100 battery or the Freedom battery with the included DC cord and the DC input cord included in the C-100 & Freedom Battery Packs. Once connected, the device can be plugged into the inverter's AC outlet which will then power the device.

    This inverter, in combination with either the C-100 or the Freedom Battery, will provide a battery option for machines that require AC power:

    Please note that the use of an inverter with a battery will reduce the run time by nearly half. Please verify the wattage requirements of the device being plugged in as some require higher than 150W.

    Can Charge the Portable Outlet Battery & the Freedom Battery from DC

    The inverter can be plugged into a DC source using the included DC cable. Then, the Portable Outlet & Freedom Battery Pack Charger is plugged into the inverter, then the charger connected to the battery, providing power to the battery.

    USB Charging Port

    The inverter also features two USB ports which are intended to charge other devices that use a standard USB cable when the inverter is connected to a DC source.

    Compatibility with AirSense and AirCurve 10 Machines

    Although the 150W inverter will provide an AC power outlet to plug the AirSense or AirCurve 10 power supply in to, it will provide a very low run time in this configuration. It is NOT RECOMMENDED to use the inverter to power these machines. Instead use the AirSense and AirCurve 10 24V Power Converter for C-100 Battery.

    Important Tips

    Battery Run Time With Inverter: Please note, use of an inverter with a battery will significantly reduce available run time. The inverter itself draws power from the battery, along with the device being used.

    Use With ResMed S7 and S8 Machines: When used with the C-100 Battery, this 150 Watt inverter is suitable to power a S7 or S8 series machine without humidifier.
