Inogen One G4 Portable Oxygen Concentrator

Built for an active and independent lifestyle, the Inogen One G4 Portable Oxygen Concentrator is one of the smallest, lightest, and quietest oxygen solutions out there. 

Equipped with Inogen’s Intelligent Delivery technology and various power options, the G4 offers worry-free therapy at home or on the road.

At just 2.8 pounds, the Inogen G4 is lighter than your average laptop, making it easy to bring wherever life takes you. 

This FAA-approved portable oxygen concentrator is roughly 6 inches long and less than 3 inches wide — small enough to fit in the included carry bag, your purse of choice, or on your lap.

With the Inogen One G4, you won’t have to worry about power safety or charging the batteries. Plug it into any wall outlet or charge it in the car — the G4 is equipped with an auto-sensing 100-240V AC power supply for worldwide use and a DC power adapter for mobile use. 

If you prefer to charge the batteries separately, make sure to use the optional G4 External Battery Charger.
