Inogen One G4 External Battery Charger

The Inogen One G4 external battery charger gives you the ability to recharge your batteries without plugging in your concentrator. It plugs into any wall outlet giving you the ability to recharge one battery at a time. 

Because the external charger isn't powering your concentrator, it can recharge your battery faster than if you plugged in your Inogen One G4. It plugs into any 110v wall outlet so you can bring it on vacation or to a friend/family member's house so you are always prepared!
