O2 Concepts Oxlife Liberty2 — DC Power Cord (Vehicle 12–15 V)

Run your Liberty2 from a car/RV/boat outlet and charge the batteries while you go

 

Keep therapy on schedule when you’re away from wall power. The Oxlife Liberty2 DC Power Cord plugs into a 12–15 V vehicle outlet to supply stable power to your Liberty2—while charging the batteries installed in the device. It’s the essential travel accessory for road trips, RV use, or everyday drives, designed by the manufacturer (OEM) for the correct voltage, connector fit, and electrical protection.

Note: This cord does not charge batteries off the device. For tabletop/off-device charging, use the external desktop battery charger (sold separately).

How to Use (quick steps)

1. Start the vehicle (recommended) to avoid draining the car battery.

2. Insert the vehicle plug into a 12–15 V outlet.

3. Connect the DC tip to the Liberty2 power port.

4. Power on the concentrator; it will run from vehicle power and charge the installed batteries.

5. Keep the brick/cable on a firm, ventilated surface while driving.

 

Tips:

• Higher continuous-flow settings draw more power—keep the engine running.

• Some cars cut power to the outlet when the ignition is off; the Liberty2 will switch to internal battery if available.

• Avoid loose splitters or low-quality adapters.

Care & Safety

• Use only with Liberty2 (OEM cord).

• Do not block vents; avoid excess heat (dashboards in direct sun).

• If there’s no power, check the fuse and replace with the same rating.

• Do not use uncertified extension/splitter devices.

• Not for aircraft outlets; follow airline policies.

Troubleshooting

• No power from DC: Confirm the vehicle outlet is live (ignition on), reseat connectors, check/replace the cord fuse, try another outlet.

• Slow charging: Depends on flow setting, battery age, and temperature; lower flow = faster charging.

• Connector gets warm: Mild warmth is normal; excess heat or odor—disconnect and inspect cord/outlet.

It varies by flow setting, battery age, and ambient temperature. Under lighter loads, charging can be similar to AC.

It’s recommended, especially at higher flow settings or longer sessions, to avoid draining the vehicle battery.

5) Do I need a prescription (Rx)?

No. This is an accessory and does not require a prescription.
