Inogen One G2 Portable Oxygen Concentrator


Prescription Required


Smaller, lighter, quieter, and more powerful than the original the InogenOne G2 (Generation 2) is the ultimate portable pulse dose oxygen concentrator! At just 4 x 11 x 9.5 inches and 7.25 lbs WITH battery it's small enough to hold in your hand. With 4 and 8-hour battery packs available the InogenOne G2 provides unparalleled freedom for active oxygen users.

Don't be deceived by its size though, the InogenOne G2 produces 20% more oxygen than the original and is available with upgraded 4-hour (12-cell) or 8-hour (24-cell) battery packs for added freedom.

The InogenOne G2 pulse dose oxygen concentrator can be used at home, in the car, or in the air -- you can use it just about anywhere. It is FAA approved for use on all commercial flights in and out of the United States. Why worry about oxygen tanks, deliveries, or refills? Upgrade to the InogenOne G2 and leave oxygen hassles behind.

The InogenOne G2 is light enough to carry in your hand, but it also comes with a handy carry bag -- with shoulder strap -- and a travel cart too so it's easy to take with you wherever you go.
