Real customers who reclaimed their mobility with our mini oxygen concentrators. You can, too.
The Oxlife Liberty 2 is designed for people who need true continuous-flow
oxygen but want a smaller, carryable alternative to a large rolling
concentrator. It provides continuous flow up to 2.0 LPM and pulse-dose
settings from 1 through 10.
Most smaller portable oxygen concentrators provide pulse dose only.
The Liberty 2 stands apart by providing both continuous flow and pulse
dose in a compact system designed to be carried.
Provides continuous-flow oxygen from 0.5 to 2.0 liters per minute
for users whose prescribed needs cannot be met by a pulse-only system.
The compact system fits inside its multifunction carry bag, giving
continuous-flow users an alternative to pulling a larger machine
behind them.
Operate the Liberty 2 from approved household power, compatible
vehicle power, or its removable rechargeable battery.
Designed for 24/7 use when operated according to the prescribed
oxygen mode, setting, and manufacturer instructions.
Batteries can be changed by the user, making it possible to carry
additional charged batteries for longer periods away from power.
The Liberty 2 meets applicable requirements for air travel.
Individual airline notice, documentation, and battery rules still apply.
The Liberty 2 fills an important gap between lightweight pulse-only
concentrators and larger continuous-flow machines.
The Liberty 2 may not be the best choice for everyone. Someone who needs
more than 2.0 LPM continuous flow may need the higher-output Oxlife
Independence. Someone who only requires pulse-dose oxygen may prefer
the lighter OxyGo NEXT NG or OxyGo FIT Plus.
The correct choice begins with the prescribed oxygen delivery method
and setting—not simply the smallest or lightest machine.
The Liberty 2 is designed to make everyday activities easier to manage
without coordinating portable tank deliveries, exchanges, or refills.
Carry the system to medical appointments, stores, restaurants, and
other everyday destinations without managing several oxygen cylinders.
Use one concentrator at home, in the vehicle, and at your destination
while staying connected to the activities and people that matter.
Take a continuous-flow option away from home without bringing a large
stationary concentrator or relying entirely on oxygen tanks.
The Liberty 2 provides two different oxygen-delivery modes. Pulse
settings and continuous-flow liters per minute are different
measurements and are not interchangeable.
0.5 to 2.0 LPM
Continuous flow delivers oxygen steadily throughout the breathing
cycle, whether or not the concentrator detects an inhalation.
This mode is commonly considered by people whose prescription
specifically calls for continuous-flow oxygen.
Settings 1 through 10
Pulse dose delivers a measured amount of oxygen when the device
detects the beginning of an inhalation.
Pulse-dose settings are machine settings and are not equal to
continuous-flow liters per minute.
Because the Liberty 2 provides continuous-flow oxygen up to 2.0 LPM,
it may be used with many compatible CPAP or BiPAP oxygen setups when
prescribed and configured correctly.
This can be especially useful for vacations, visits with family, and
other overnight trips when transporting a larger stationary
concentrator would be inconvenient.
CPAP and BiPAP compatibility depends on the prescribed oxygen flow,
the sleep device, the oxygen connection, and the healthcare provider’s
instructions.
Keep the backup oxygen supply recommended by your healthcare provider
available during overnight use.
The Liberty 2 can operate from approved AC household power,
compatible DC vehicle power, or its removable rechargeable battery.
The Liberty 2 can operate from compatible vehicle power and meets
applicable requirements for approved portable oxygen concentrators
during air travel.
Package contents can vary. Review your written order to confirm included
batteries, accessories, and warranty coverage.
Each model serves a different oxygen requirement and mobility priority.

Concentrator weight:
approximately 6.35 pounds without the battery.
Total carrying weight is higher when the battery and carry bag are included.
Approximate dimensions:
9.9 × 9.9 × 3.8 inches.
Continuous flow from 0.5 to 2.0 LPM in available increments.
Pulse settings 1 through 10. Pulse settings are not equivalent to
continuous-flow liters per minute.
Battery time may reach approximately 4.5 hours at lower pulse
settings under favorable conditions. Continuous-flow operation
provides shorter battery duration.
Operates from approved AC household power, compatible DC vehicle
power, or a charged removable battery.
Manufacturer-stated oxygen concentration is approximately 87% to
95%, subject to operating conditions and specifications.
Yes. It provides continuous-flow oxygen from 0.5 to 2.0 liters
per minute.
Yes. It provides pulse-dose settings from 1 through 10.
It is designed for 24/7 operation and may provide prescribed
continuous-flow oxygen overnight.
Its continuous-flow capability may support compatible CPAP or
BiPAP equipment when the connection and oxygen flow have been
prescribed and confirmed.
Yes. It can operate from compatible DC vehicle power when used
according to the manufacturer instructions.
The system is designed to operate and charge from approved AC
or compatible DC power. Charging performance can vary according
to setting and power source.
It meets applicable requirements for accepted portable oxygen
concentrators. Contact the airline before departure and follow
its documentation and battery rules.
No. It concentrates oxygen from the surrounding air while it
has an appropriate power source.
Yes. The rechargeable battery is removable and user replaceable.
Battery duration depends heavily on delivery mode and setting.
Lower pulse settings provide longer operation than continuous-flow
settings.
No. Pulse-dose settings and continuous-flow liters per minute
are different measurements.

The Liberty 2 gives you the freedom of portability while also offering continuous flow options when needed.
Key advantages:
The Liberty 2 is best known for delivering continuous flow oxygen up to 2.0 LPM while still being a portable, wearable system —
a major benefit for users who prefer or require continuous flow for certain situations. :contentReference[oaicite:2]{index=2}
Note: exact settings and usage should always match your prescription and clinician guidance.
In addition to continuous flow, the Liberty 2 offers pulse settings 1 through 10, giving you flexibility across a wider range of needs
— all in one device. :contentReference[oaicite:3]{index=3}
Battery runtime varies by mode and setting. Many users like the Liberty 2 because it supports both continuous and pulse delivery in one platform,
reducing the need to switch devices for different situations.
Typical continuous-flow runtimes (varies by setting):
These are commonly published estimates; real-world results vary by battery health, altitude, temperature, and usage. :contentReference[oaicite:4]{index=4}
This system is a great fit if you:
The Liberty 2 is commonly sold with a 3-year manufacturer warranty (confirm current coverage at time of purchase).
We carry new units only — no refurbished or used equipment. :contentReference[oaicite:5]{index=5}
