The Inogen G4 Portable Oxygen Concentrator technology incorporates dual exhausts and dual intakes, providing maximum heat dissipation to keep your O2 device running cooler and longer. This machine can operate from three separate power sources–battery, DC power (car, truck, RV, boat), or AC power from your home. AC power is also used to recharge the battery. The Inogen One G4 machine is designed to operate 24/7 to meet the needs of the oxygen patient. You may select between two Inogen One battery options—the standard single battery or the upgraded double battery.
