Inogen G4 External Battery Charger
Portable Oxygen Concentrator Charger
The Inogen One G4 External Battery Charger will charge your Inogen One G4 single and double batteries.
If you are active and need to recharge multiple Inogen One G4 batteries simultaneously, then order an extra charger to help you charge more batteries as needed. If you need to charge multiple batteries, then you should consider an external charger to speed up the process.
With an external charger, you can be charging one battery while charging a second battery in your POC. Extra batteries give you more power for the ultimate freedom and an external charger makes the process even more efficient.
