Double Battery for Inogen One G5 Oxygen Concentrator

With twice the duration as the G5 single battery, the Inogen One G5 Double Battery lets you enjoy weekend getaways and take long flights without running out of oxygen. It offers up to 13 hours of runtime, making it the perfect travel accessory for your G5 Portable Oxygen Concentrator and a reliable backup power source during emergencies. 


  • Compatible with the Inogen One G5 Portable Oxygen Concentrator
  • LED indicators display the remaining battery life
  • Provides up to 13 hours of runtime at flow setting 1
  • Full charge takes up to 6 hours (attached to the concentrator) or 9 hours (using the G5 External Battery Charger)
  • FAA-approved

Checking the available charge is easy — simply press the green battery icon button on the G5 Double Battery, and the LED indicators will illuminate to show the battery status. 4 LEDs indicate that the battery has 75% to 100% remaining charge, while 1 blinking LED means it needs to be recharged. 

Charging the battery while inside the G5 concentrator will only take up to 6 hours. Just leave it in the concentrator and plug the unit at home using the G5 AC Power Supply or in the car using the G5 DC Power Adapter. You can also charge it separately with the optional G5 External Battery Charger, which can fully charge the battery in 9 hours or less.
