Compact, Sleek Design

Weighing in at 4.8 lbs and measuring 8.75 inches long, 3.0 inches wide, and 8.25 inches high, the concentrator is easily portable and can be taken along for daily activities or while traveling. The included carry bag is specifically designed for the device and offers a shoulder strap to increase usability.

Approved for Travel

The G3 device is approved for travel. Inogen's oxygen therapy is safe for use in the car, on trains, on boats, and aboard planes. When traveling, it is recommended to carry one or two battery cells to ensure the device can be run without electrical power. A DC adapter is included to power the G3 where DC power is avaialble.

The G3 Portable Oxygen Concentrator is FAA approved for airplane use. Notify the airline in advance if a power port is needed during the flight.

Intelligent Delivery Technology

The G3 features Intelligent Delivery technology, which detects shallow breaths and is equipped to counter the dip in breaths per minute by increasing the flow of oxygen. In addition to increasing oxygen flow when needed, particularly during sleep, the Inogen G3 transmits oxygen to the user within the first 400 milliseconds of inhalation. The goal is to provide the user with the greatest amount of oxygen at the most optimal time.

Pulse Dose Flow Settings

The G3 concentrator offers Pulse Dose technology, which streams oxygen rich air to the user during inhalation only. Pulse dose oxygen allows the cocentrator to operate more effeciently, allowing for longer battery run times opposed to continuous flow.

Rechargeable Battery Power

The G3 uses a lithium ion rechargeable battery. If fully depleted, it may take up to 4 hours to recharge a singular battery completely, and it may take up to 8 hours to recharge an extended battery. However, the battery can be charged before it is empty.
