Inogen One G4 Portable Oxygen Concentrator

Weighing just 2.8lbs (1.27kg), the INOGENONE® G4 is compact, lightweight, and stylish. It's the smallest and lightest portable oxygen concentrator in our range and offers 3 pulse flow settings.

The G4 runs quietly, producing less noise than a typical indoor conversation, making it discreet and easy to use. The user-friendly interface includes a white back-lit LCD display that shows the current pulse flow setting and remaining battery level clearly.

The G4's smart delivery system adjusts the oxygen output based on your breathing rate. When you're active, it provides shorter bursts of oxygen, and when you're resting or sleeping, it delivers longer bursts. This ensures you always receive the right amount of oxygen as prescribed. The device comes with both a mains power adapter and a car charger.
