Inogen One G4 Double Battery

Introducing the Inogen One G4 Double Battery, the perfect companion for your active lifestyle. This high-capacity battery doubles the run time of your Inogen One G4 Portable Oxygen Concentrator, giving you up to 5 hours of continuous use on setting 1.

Now you can run errands, travel farther, and stay out longer without worrying about running out of power. The G4 Double Battery also offers backup power in the event of a loss of AC or DC power.

You can conveniently charge the battery while it is attached to the G4 concentrator, or charge it separately using the G4 External Battery Charger.

For ultimate flexibility, the battery charges when the concentrator is in use, ensuring uninterrupted oxygen therapy. Both the G4 AC Power Supply and G4 DC Adapter can be used to charge the battery.
