The Inogen One G4 is very similar to the Inogen One G3 model from what our research shows.

It is also approved for in-flight use so it is a great device for travel. Please read our full review of the Inogen One G4 portable oxygen concentrator below.

Step #3 Seniors Review of the Inogen One G4 Portable Oxygen Concentrator

We spoke with two seniors who are using the Inogen One G4 model as their primary portable oxygen. Each of the customers liked their concentrator and said that they had very few issues with using the POC in daily life. One customer said that he has been using the unit for five months and it hasn’t caused a single issue. He purchased the larger sized battery after reading reviews about the battery life being a concern but since he keeps his unit charged while he’s in the car he hardly ever gets a low battery. One customer mentioned that the vents on the sides can get warm or seem to almost overheat during the summer months.
