Description
Quick answer: This is the genuine ResMed DC/DC converter (65W) for the AirMini travel CPAP (part 38839) — it lets you run the AirMini from a 12V or 24V DC power source, such as a vehicle cigarette-lighter socket in a car, RV, truck, or boat. With a long ~9’9″ (3 m) cord, it’s the go-to for road trips, camping, and off-grid or vehicle use. Important: this is the only DC cord that should be used with the AirMini — a non-ResMed converter can damage the device, and it won’t work with other machines. Device not included.
What’s included
- 1 × ResMed AirMini DC/DC converter, 65W (part 38839, ~9’9″ cord)
AirMini machine and DC source not included.
About this part
To run the AirMini away from a wall outlet, you can’t feed it raw 12V or 24V directly — the power has to be converted to what the device needs. The DC/DC converter does exactly that: it takes 12V or 24V DC from a vehicle’s cigarette-lighter socket (or a compatible battery source) and converts it to run the AirMini.
This is the piece that makes off-grid and vehicle therapy work on the AirMini: road trips, camping, van and RV setups, boats, or long journeys where you want to run the device from the vehicle rather than mains power. The generous ~9’9″ (3 m) cord gives plenty of reach to position the device comfortably.
Use only the genuine ResMed DC converter. This is the only DC cord that should be used with the AirMini — a non-ResMed converter can damage the device, and this cord won’t work with other ResMed machines or other manufacturers’ devices.
Note it’s distinct from the 20W AC power supply (38828), which runs the AirMini from a wall outlet; this DC/DC converter runs it from a 12V/24V DC source.

Frequently asked questions
What does the DC/DC converter do?
It converts 12V or 24V DC from a vehicle outlet or compatible battery into the power the AirMini needs, so you can run the device from DC.
Which device does it work with?
Only the ResMed AirMini. It won’t work with other ResMed machines or other manufacturers’ devices.
Can I use a generic DC cord instead?
No — this is the only DC cord that should be used with the AirMini. A non-ResMed converter can damage the device.
Where can I use it?
From a 12V/24V DC source — a car, RV, truck, or boat cigarette-lighter socket, or a compatible battery. Great for road trips and camping.
How is it different from the 20W AC power supply (38828)?
The 20W AC supply runs the AirMini from a wall outlet; this DC/DC converter runs it from a 12V/24V DC source (vehicle/battery).
Do I need a prescription?
No — power accessories do not require a prescription.
Can I get it delivered in Brooklyn or shipped nationwide?
