External Battery Charger for Inogen G4

Always be prepared with a fully charged backup and complete your travel oxygen setup with the Inogen One G4 External Battery Charger. Designed to charge your extra battery separately from the G4 Portable Oxygen Concentrator, it allows for longer unplugged oxygen therapy and more freedom. 


  • Compatible with the Inogen One G4 Batteries (Single and Double)
  • Fast recharging time: approx. 2 hours (Single Battery) and 4 hours (Double Battery)
  • LED lights show the battery status
  • Lets you charge your G4 battery separately from the concentrator

With the G4 External Battery Charger, you can charge multiple batteries at once. Insert one battery in the concentrator, plug the unit into a wall outlet or DC power port, and charge your spare using the G4 battery charger. Then, enjoy peace of mind knowing you have a backup power supply ready for adventures and emergencies.

Another advantage of the G4 External Charger is its faster charging speed. It fully charges a depleted G4 Single Battery in just 2 hours and the G4 Double Battery in 4 hours, significantly faster than the concentrator.

With a red LED indicating active charging and a green LED signaling a fully charged battery, the G4 charger keeps you up to speed on the battery status. To top it off, it features a compact and lightweight design, which fits easily in your G4 backpack or carry bag.
