The Inogen One G5 Portable Oxygen Concentrator with 16-Cell Extended Battery delivers the longest runtime of any G5 configuration — up to 13 hours of continuous use on a single charge.

The G5 combines Inogen's Intelligent Delivery Technology with a lightweight, FAA-approved design — pulse dose settings 1–6, quiet operation at 38 dBa, and a compact form factor that fits in a carry bag.
