Double Your Independence and Go Further

Breathe easier on the go with the Inogen One G4 8-Cell Double Battery. Designed for users who refuse to let oxygen needs limit their schedule, this high-capacity power bank doubles the range of the standard battery. It provides the security you need for all-day outings, wedding receptions, or transatlantic flights, all while maintaining the ultra-lightweight profile that makes the G4 famous.

Extended 5-Hour Runtime

Providing up to 5 hours of clinical oxygen delivery on setting 1, this 8-cell battery allows you to stay away from the wall outlet longer. This increased capacity reduces "range anxiety" and allows you to participate in activities that the standard single battery cannot accommodate.

Compact, Seamless Power

Despite its expanded capacity, the double battery remains remarkably small. It adds less than a pound to the device's weight, keeping your Inogen G4 comfortable for long-term wear on your shoulder or belt without hindering your daily motion or causing strain.
