Use the 150W Sine Wave Power Inverter to:

Charge the CPAP Battery in a Vehicle
Safely and efficiently charge your CPAP Battery via the cigarette lighter/power socket of a vehicle.

Power Devices Without DC Capability

Power Other Small Electronic Devices
Allows you to use the CPAP Battery to power other small electronic devices that operate from 12V and do not have a DC power cable that could be plugged into the DC input cord included with the CPAP Battery Kit. Simply connect your device to the inverter via the two prong plug or USB ports.


Soft Start Technology (SST) – gradually and safely ramps up the output voltage to start difficult motorized loads and protects sensitive appliance circuits.

Turbo cooling fan prevents thermal runaway and extends the life of the inverter by keeping components cool.

Two-prong plug and USB input ports allow for easy connection to many different types of small electronic devices.

The 150W Sine Wave Power Inverter is not proprietary to the Freedom CPAP Battery and can be used with other devices.

Vehicle Charging Notes: When using the power inverter to charge the CPAP Battery in a vehicle, the vehicle does not need to be running in order to ensure the CPAP Battery receives proper voltage to successfully charge as long as the cigarette lighter/power socket is providing power. However, when charging any electronic device or external battery in a vehicle, it is recommended that the vehicle be running during the charging process to help prevent draining the vehicle's battery.
