Inogen One G5 Portable Oxygen Concentrator (Pulse Dose)

Inogen G5 Portable Oxygen Concentrator

The Inogen One G5 is the next generation of portable oxygen concentrators, designed to provide unmatched freedom and flexibility for oxygen users.

Weighing in at just 4.7 pounds (with a single battery), the G5 is lightweight, quiet, and discreet, making it perfect for running errands, traveling, or simply enjoying everyday activities.

Powerful Performance
With a battery duration of up to 6.5 hours (single battery on flow setting 1) and the ability to deliver up to 1260 ml of oxygen per minute, the Inogen G5 is as powerful as it is portable.

If you need even more battery life, the G5 Double Battery provides up to 13 hours of runtime on setting 1. Furthermore, its six flow settings allow you to adjust oxygen delivery to suit your activity level.   

Intelligent Pulse Dose Delivery
The G5 uses intelligent pulse dose delivery technology to ensure efficient and consistent oxygen delivery. It senses inhalation onset, delivering a burst of oxygen at just the right moment.

When your breathing rate changes, the Inogen One G5 adapts to your breathing and delivers oxygen only when you need it. 

Quiet Operation
At only 38 decibels on setting 2, the G5 ranks among the quietest portable oxygen concentrators on the market. Similar to the soft hum of your computer or the pattering of rain, it allows you to use oxygen discreetly in public.

Versatile Power Options
The Inogen One G5 boasts multiple power options — AC, DC and battery — for optimal safety and convenience. The included auto-sensing 100-240V AC Power Supply can be used worldwide, while the DC Power Adapter lets you use and charge the G5 in the car.

As for the single and double lithium-ion batteries, they can be charged while connected to the G5 or separately using the G5 External Battery Charger.  

User-Friendly Interface
Featuring a large, backlit LCD display and an intuitive interface, the Inogen One G5 is ideal for new oxygen users. The screen clearly displays the current flow setting and battery life.

Visual cues on machine status are provided by indicator lights next to the screen, which light up green when breathing is detected and flash yellow to indicate low battery or other maintenance needs. Users can also easily adjust oxygen flow with just a touch using the +/- buttons. 

Inogen Connect
With the Inogen Connect (iOS/Android) mobile app, you’ll have the real-time status of your oxygen concentrator at your fingertips. Simply pair the G5 to your phone via Bluetooth.

Then, on the app, you can easily check the battery life, current flow settings, remaining column life, hours of use, and more. The Inogen Connect app also alerts you when it’s time to replace the columns and filters.
