O2 Concepts Oxlife Liberty2 Oxygen Concentrator
O2 Concepts Oxlife Liberty2 Portable Oxygen Concentrator
Overview
The O2 Concepts Oxlife Liberty2 is the most capable wearable in the Oxlife line — a compact, dual-mode portable oxygen concentrator that pairs continuous flow up to 2.0 LPM with the largest pulse dose of any POC on the market (settings 1–10, with 8–80 mL boluses per breath). Its seven fine-grained continuous-flow settings, adjustable in 0.25 LPM increments, let you match a prescription precisely, and it delivers up to 2,000 mL of oxygen — roughly twice the output of most portables — all in a body that weighs about 6.5 pounds and fits under an airline seat.
Powered by O2 Concepts' patented Energy Smart Technology, it offers a long battery life (up to 4.5 hours) and is chargeable on all settings while in use, on AC power at home or DC power in the car. A clear color LCD and simple control panel keep everyday use easy, while the proprietary DNA cellular platform adds remote performance monitoring and GPS-based loss and theft protection. FAA-approved for air travel and made in the USA, the Liberty2 ships with a multipurpose carry bag for going anywhere.
Key Features
- Wearable dual-mode design — continuous flow up to 2.0 LPM (0.25 increments, 7 settings) plus pulse dose settings 1–10.
- Largest pulse dose of any POC on the market (up to setting 10; 8–80 mL boluses).
- Delivers up to 2,000 mL of oxygen — about twice the output of most portables.
- Compact and lightweight (about 6.5 lbs) — fits under an airline seat.
- Energy Smart Technology with long battery life (up to 4.5 hours); chargeable on all settings while in use.
- Charges on AC (home) or DC (car) power.
- Color LCD with an easy-to-use control panel.
- DNA cellular platform with GPS — remote performance monitoring and loss/theft protection.
- FAA-approved for commercial air travel.
- Made in the USA; includes a multipurpose carry bag; 3-year warranty.
The Liberty2 sits at the top of the wearable Oxlife line — it takes the original Liberty's dual-mode design and pushes continuous flow to 2.0 LPM and pulse dosing to setting 10, the highest of any POC, with fine 0.25 LPM continuous increments for precise matching to a prescription. At about 6.5 pounds it stays genuinely wearable and fits under an airline seat, yet delivers roughly 2,000 mL — about twice most portables. Choose it over the standard Liberty when you need the extra continuous flow or higher pulse settings; step up to the cart-based Independence only if you need continuous flow beyond 2 LPM. The DNA platform's GPS is a welcome extra on a device this valuable, and battery upgrades (two or three batteries) are available for longer days.

How is the Liberty2 different from the original Liberty?
The Liberty2 raises continuous flow to 2.0 LPM (versus 1.5), adds more pulse settings (1–10 versus 1–9, the largest of any POC), offers fine 0.25 LPM continuous increments across seven settings, and includes GPS. It's the same wearable concept with more range and precision.
Does it do both continuous flow and pulse dose?
Yes — continuous flow up to 2.0 LPM plus pulse dose across settings 1–10, switchable on one unit. Its true continuous flow supports steady daytime and nighttime use; check with your provider about compatibility with any CPAP or BiPAP equipment.
How long does the battery last, and can I extend it?
Up to 4.5 hours per charge, and it's chargeable on all settings while in use via AC or DC power. For longer days, battery upgrades (two or three batteries) are available so you can swap in a charged pack on the go.
