Single Battery for Inogen One G4 Oxygen Concentrator

Whether you’re looking for a backup or replacement battery for your G4 Portable Oxygen Concentrator, the Inogen One G4 Single Battery offers the perfect solution for an independent lifestyle. Approved by the FAA for in-flight use, featuring a runtime of up to 2.7 hours, it lets you continue your oxygen therapy on the go and doubles as a reliable backup power supply during outages. 


  • Compatible with the Inogen One G4 Portable Oxygen Concentrator
  • LED indicators display the remaining battery life
  • Provides up to 2.7 hours of runtime at flow setting 1
  • Full charge takes up to 3 hours (attached to the concentrator) or 2 hours (using the G4 External Battery Charger)
  • FAA-approved

Designed with four LED indicators, this battery gives you an easy glimpse of the remaining charge. That means there’s no need to put it in the concentrator just to find out whether it needs to be recharged – simply press the battery icon button and wait for the LEDs to illuminate.

If only one LED lights up and blinks, place the G4 Single Battery in the concentrator and plug the unit into a DC or AC power source. The battery will fully charge in three hours or less. For faster charging, pair it with the G4 External Battery Charger, which can fully charge a depleted Single Battery in just two hours.
