Product Overview
BiXPower DC24V-AS11-USBC power converter
The adapter is designed to connect a compatible USB-C PD power source to a ResMed AirSense 11 CPAP machine.
It eliminates the need for a separate AC inverter when using a suitable DC battery, providing a compact and convenient power connection.
Complete Converter and USB-C Input Cable
Included power converter and USB-C PD input cable
The package includes the DC-to-DC converter and a dedicated USB-C PD input cable.
The USB-C cable connects to a compatible USB-C PD power source and provides the appropriate DC input to the converter.
How the USB-C CPAP Power Connection Works
USB-C power source to converter to AirSense 11 CPAP
The power connection follows three simple steps:
- USB-C PD Power Source: Connect the USB-C cable to a compatible battery or power bank that supports 20V USB-C PD output.
- DC Power Converter: The converter receives the DC input and regulates it to 24V DC.
- ResMed AirSense 11: Connect the special output plug to the AirSense 11 power input.
This arrangement allows your CPAP machine to operate from a suitable portable DC power source without a separate AC inverter.
USB-C Input and 24V Output Connections
USB-C PD input and regulated 24V DC output
The USB-C input cable requests a 20V power profile from a compatible USB-C PD source. The converter then supplies regulated 24V DC through the dedicated AirSense 11 connector.
USB-C Compatibility Requirement
The USB-C power source must support USB Power Delivery with a 20V output profile and sufficient power capacity.
A 100W USB-C PD source supporting 20V/5A is recommended. Not all USB-C ports support this power level, and a basic 5V USB-C charging port will not operate the converter correctly.
The converter itself is limited to 65W maximum output.
Wide-Input DC-to-DC Converter
Converter module with 9V–32V DC input capability
The converter module itself accepts approximately 9V–32V DC input through its 5.5 x 2.5mm female barrel connector.
In this USB-C kit, the included PD cable is used to obtain 20V DC from the USB-C source.
The converter's wide input range also allows use with other appropriately configured DC power sources, provided connector polarity, voltage, and available current are correct. Additional connection accessories may be required.
Converter Electrical Specifications
Converter label and electrical ratings
The converter is rated for a maximum 65W output. It converts compatible DC input power to regulated 24V output for the AirSense 11.
Always ensure that the connected USB-C power source provides sufficient power for the CPAP operating conditions.
Compact and Lightweight for Travel
Compact converter designed for portable power applications
Weighing approximately 142g (5 oz), the converter is easy to carry with your CPAP accessories.
Converter housing dimensions: approximately 90 x 36 x 26mm
Its compact housing is suitable for travel bags, CPAP carrying cases, and portable battery setups.
Included USB-C PD Input Cable
USB-C PD to 5.5 x 2.5mm DC input cable
The included USB-C input cable connects a compatible USB-C PD power source to the converter's 5.5 x 2.5mm female DC input port.
The cable is designed to negotiate a 20V output from a suitable USB-C PD power source.
Important: The cable does not convert a basic 5V USB-C output into 20V. The power source itself must support the required USB-C PD profile.
Power Your AirSense 11 from a USB-C Battery
Example USB-C PD battery connection — battery not included
Many portable rechargeable batteries and power banks offer USB-C PD output. With a compatible 20V USB-C PD source, the BiXPower converter provides a convenient way to supply regulated 24V power to your AirSense 11.
This can be useful for camping, RV travel, portable CPAP operation, and backup power planning.
Choosing a Battery
For best compatibility, select a rechargeable battery with a USB-C PD output rated for 100W (20V/5A).
Check the battery's actual USB-C PD output specifications rather than relying only on its total capacity or advertised charging wattage.

Frequently Asked Questions
Can I power my ResMed AirSense 11 from a USB-C power bank?
Yes, provided the power bank supports USB-C Power Delivery with a suitable 20V output profile and sufficient available power. A 100W USB-C PD source is recommended.
Will any USB-C port work?
No. Standard USB-C ports that provide only 5V, or do not support the required USB-C PD profile, will not work correctly with this adapter.
Does the converter include a rechargeable battery?
No. The package includes the DC converter and USB-C PD input cable. A suitable USB-C battery or power source must be purchased separately.
Does this converter increase the USB-C battery's power?
No. The converter changes the input voltage to regulated 24V DC. It does not create additional energy, and some energy is lost during conversion.
Can I use this adapter with the heated humidifier?
Heated humidification and heated tubing can significantly increase power demand. Operation is limited by the converter's 65W maximum output and the available power from the USB-C source. Verify the CPAP's actual power requirements before using heating functions.
How long will my AirSense 11 run on a USB-C battery?
Runtime depends on battery capacity, therapy settings, humidifier operation, heated tubing, and conversion efficiency. A larger-capacity battery generally provides longer runtime under otherwise identical conditions.
Can I use a 12V battery instead of USB-C?
The underlying converter supports a wide 9V–32V DC input range. However, direct battery connection requires a suitable input cable, correct polarity, and sufficient input current. The included USB-C cable is specifically intended for compatible USB-C PD power sources.
Will this converter work with ResMed AirSense 10?
This kit includes the special power connector intended for ResMed AirSense 11. Do not assume compatibility with AirSense 10 or other CPAP models that require different connectors or power configurations.
