Inogen One G4 Portable Travel Oxygen Concentrator – Pulse Dose

The Inogen One G4 Portable Travel Oxygen Concentrator – Pulse Dose is a compact, lightweight pulse dose oxygen concentrator designed for supplemental oxygen users who want greater mobility at home and while traveling. Weighing approximately 2.8 lbs with a battery, the Inogen One G4 provides three pulse dose flow settings (1–3) and uses Inogen’s Intelligent Delivery Technology® to deliver oxygen during inhalation.

Designed for everyday portability, the Inogen One G4 can operate from its rechargeable battery, an AC power source, or DC power in a vehicle. This allows users to operate and recharge the portable oxygen concentrator at home, in the car, and while traveling. The Inogen One G4 is FAA-approved for use aboard commercial aircraft in accordance with applicable requirements. Travelers should contact their airline before departure to confirm the airline’s current requirements, battery requirements, and any documentation needed for supplemental oxygen use during a flight.

At approximately 2.8 lbs with a battery, the Inogen One G4 is designed for oxygen users who prioritize portability. Its compact design makes it easier to carry during everyday activities, errands, appointments, and travel compared with larger oxygen systems. The G4 provides three pulse dose oxygen settings from 1–3. Unlike continuous-flow oxygen concentrators, the G4 is a pulse dose device, meaning oxygen is delivered in response to the user’s breathing rather than continuously at a specified liter-per-minute flow.

Inogen One G4 Battery Options:

The Inogen One G4 is available with different rechargeable battery configurations to accommodate different portability needs.

• Single Battery: Up to approximately 3 hours of use
• Extended Battery: Up to approximately 5 hours of use

Actual battery runtime varies depending on the oxygen flow setting, battery condition, operating environment, and other factors. Higher flow settings generally result in shorter battery runtime.

The battery can be recharged using the included AC power supply or DC power cable.

AC & DC Power for Home and Travel:

The Inogen One G4 includes both AC and DC power options, allowing the concentrator to operate and charge in multiple environments.

The AC power supply can be connected to a compatible electrical outlet for home or travel use. The DC power cable allows the G4 to receive power from a compatible vehicle DC outlet.

The Inogen One G4 can continue providing oxygen while connected to an appropriate external power source, allowing users to receive prescribed oxygen therapy while the battery is charging.
