The Inogen One G4 is designed for 24 h use! The pulse dose delivery system is energy efficient and completely portable at just 1.3 kg including a battery.
The Inogen One G4 is officially the smallest and lightest portable oxygen concentrator ever released by Inogen. Weighing less than 1.3 kg with the single battery, the Inogen One G4 is more than 40% lighter than the Inogen One G3 and it is about half the size! It even weighs less than some of the most commonly used portable oxygen cylinders.
It is a pulse flow delivery system, which means it does not offer continuous flow, but it offers settings 1–3. It is equipped with Inogen standard ‘Intelligent Delivery Technology’ to ensure the unit detects your breath to delivery oxygen with incredible accuracy.
