Inogen One G3 Product Overview

Currently one of the smallest, lightest portable concentrators that produces medical oxygen and offers an extremely long lasting battery is the Inogen One G3. The oxygen machine was created to provide users with the highest level of independence. Smaller in size, lighter in weight, and produces more oxygen per pound than its predecessor, the Inogen One G2. Not requiring the use of a rolling cart, it is a portable concentrator that you can hold in one hand. You will never have to worry about oxygen running out, because this unit never needs to be refilled.

The Inogen G3 is ultra light, weighing less than 5 pounds with the 8 cell battery and 5.7 with a 16-cell battery and includes a carry bag that can be worn over your shoulder for easy mobilization. The batteries were created and piloted to last a very long time. At a setting of 2, the 8-cell battery can last up to 4 hours and the 16-cell battery can last up to 7 to 8 hours. With a faster than normal recharge time, the rechargeable batteries can reload in a few short hours. The 8-cell battery will recharge in 4 hours on average and the 16 cell battery will recharge in 6 hours. This unit is one of the smallest sized oxygen concentrators ever produced, measuring  only 7.25 inches tall, 3 inches wide and 8.75 inches long. With oxygen concentration levels at around 90%, It is a pulse dose portable concentrator that operates on setting from 1 to 5. At only 39 decibels, the machine is hardly noticeable. The unit can hardly be heard! So discreet that you can use it in a library or church without noticing it. Flow settings and battery life are beautifully highlighted on the easy to read LCD screen.

Airline approved for user ability during flights. Also can be used on most cruise ships and buses, making the Inogen G3 an excellent breathing companion for travel far and near!

Included in the Inogen One G3 Starter Package is: 8 cell battery, AC power supply, DC power cable, carry bag, cannula, and manual.
