Description

The Inogen One G5 Portable Oxygen Concentrator is a lightweight pulse dose device built for people who want reliable oxygen therapy support without sacrificing mobility. At just 4.7 lb with a single battery, it's designed for seniors, caregivers, COPD patients, and travelers who need a dependable oxygen concentrator for daily use and travel.

The G5 delivers pulse dose oxygen only across six flow settings (1–6) — the widest setting range in the Inogen One lineup — timing oxygen delivery to match the start of inhalation. Battery options scale to fit your day: a single battery runs up to 6.5 hours at setting 1, while a double battery extends that to up to 13 hours, with recharge times of 3 and 6 hours respectively.

The G5 is designed to meet FAA acceptance criteria for onboard use, making it a common choice for air travel. Airline requirements can still vary, so always confirm documentation and plan spare battery capacity for your full trip plus potential delays.
