Frequently Asked Questions (FAQ)

What is the advantage of a continuous flow setting on a portable device?

Most compact portable concentrators only offer pulse-dose delivery, meaning they only emit oxygen when they detect you inhaling. The Oxlife Liberty2® offers both pulse and continuous flow modes. Continuous flow supplies a steady, uninterrupted stream of oxygen, which is medically necessary if you use a CPAP/BiPAP machine at night, breathe through your mouth while sleeping, or require a fixed flow rate during specific therapeutic exercises.

How long does the battery last on continuous flow vs pulse dose?

Battery life varies depending on your medical flow setting. On a single battery, pulse mode ranges from roughly 4.5 hours at setting 1 down to 2.5 hours at setting 5. Continuous flow demands more power, delivering about 3.25 hours at 0.5 LPM down to 1 hour when running at full 2.0 LPM continuous output.

Can I plug this device into a car outlet while driving?

Yes, absolutely. The system includes a heavy-duty DC vehicle power adapter. O2 Concepts engineered this machine with a powerful internal inverter, meaning the Liberty2® can fully operate on both continuous flow and pulse dose settings while simultaneously recharging the battery as you drive.
