This power adapter can convert 12V DC (Range 10V ~ 30) power to 24V DC power. Its 24v output has a special connector Compatible with ResMed Airsense 10 devices.
This DC Converter works with the following AirStart™ 10, AirSense™ 10, and AirCurve™ 10 machines manufactured by ResMed:
AirStart™ 10 CPAP with HumidAir™ Heated Humidifier
AirStart™ 10 Auto CPAP with HumidAir™ Heated Humidifier
AirSense™ 10 CPAP Machine with HumidAir™ Heated Humidifier
AirSense™ 10 Elite CPAP Machine with HumidAir™ Heated Humidifier
AirSense™ 10 AutoSet CPAP Machine with HumidAir™ Heated Humidifier
AirSense™ 10 AutoSet for Her CPAP Machine with HumidAir™ Heated Humidifier
AirCurve™ 10 S BiLevel Machine with HumidAir™ Heated Humidifier
AirCurve™ 10 VAuto BiLevel Machine with HumidAir™ Heated Humidifier
Please note that this power adapter itself does not generate any power. It just converts the 12V (Range 10V to 21V) DC power to 24V DC power with special signal for CPAP machine. In order to provide enough power, please make sure the connected power source can supply enough power for converting. For a 12V battery, it may need to be able to provide up to 7 ~ 8 Amps power to start a CPAP machine even the machine may just need 1 ~ 2 Amps
Two ways to connect the converter:
1. If your battery or other DC power source output port is a 5.5 x 2.5mm female port, you may use enclosed Input Cable to make connection, just plug one end to DC Converter input port, another end connect to battery or other DC power source output port.
Battery and CPAP Machine Not Included Please note that input cable connector size is 5.5 x 2.5mm. Some battery output port size may be 5.5 x 2.1mm. In this case, the input cable may Not make a good tight connection with battery. The converter may not work properly. If this happens, you will need a BiXPower CNT-C3 connector to change the connector on input cable from 5.5 x 2.5mm to 5.5 x 2.1mm.
2. If your battery or other DC power source has a output cable with 5.5 x 2.5mm male connector, you can directly plug it to 5.5 x 2.5mm female input port on converter.

Features:
Super small size: dimension is 2.5" x 1.9" x 0.7" ( 63.5 x 48.9 x 16.9mm)
Super light weight: only 2.54 oz (72g)
Super high efficiency: up to 96%
A regular DC converter efficiency is around 80% ~ 85%, which means 15% ~ 20% power will be used by the converter itself. For a 85% efficiency rate power adapter to deliver 90W power, it will take 106W power from a power source ( such as a battery). This DC Converter's efficiency rate is up to 96%, which means only around 4% power will be used by the converter itself. To deliver 90W power, it only needs 94W power from a power source.
