Compare Inogen One G2 and Inogen One G3 with DeVilbiss iGo

The DeVilbiss iGo is a portable oxygen concentrator from DeVilbiss. Just like the CAIRE Eclipse, it is more a transportable than a portable oxygen concentrator. Because it is able to also provide a continuous flow of oxygen, the concentrator is much heavier and larger compared to the Inogen One concentrators. The iGo is not suitable to be carried around.

The concentrator gives a maximum continuous flow of 3 liters per minute and has 6 pulse settings.

As only one in our comparison, the DeVilbiss iGo cannot run on a DC power source and charge the battery at the same time.
