Inogen One G3 Portable Oxygen Concentrator


Included In Inogen One G3 Portable Oxygen Concentrator Standard Package:

      • Inogen One G3 Portable Oxygen Concentrator
      • (G3) Carry Bag AC Power Supply
      • (G3) DC Power Cable
      • (G3) 8 Cell Battery



The Inogen One G3 delivers oxygen in a pulsed dose, called a bolus, each time you breathe in. As your respiratory rate (breathing pattern) changes the Inogen One G3 actively responds to make the best use of oxygen delivery. During periods of activity breathing rates increase so the G3 reduces bolus size to ensure oxygen is not wasted on expiration. During periods of rest and sleep breathing rates typically decrease so the G3 increases bolus to account for the longer periods of inspiration. At 10 breaths per minute, the Inogen One G3 delivers double the bolus size as when the breathing rate is 20 BPM.


The Inogen One G3 is currently one of the smallest, lightest portable concentrators that produces medical oxygen and offers an extremely long lasting battery. The oxygen machine was designed to provide users with the highest level of independence. It has, all the same, features as its predecessor, the Inogen One G2 but it is smaller in size, lighter in weight and produces more oxygen per pound. It is a portable concentrator that you can hold in one hand and does not require a rolling cart. Forget about your oxygen tanks, this unit never needs to be refilled so you will never have to worry about oxygen running out!

The Inogen G3 weighs less than 5 pounds with the 8 cell battery and 5.7 with a 16 cell battery. The G3 unit comes with a carry bag that can be worn over your shoulder for easy transportation. The batteries were made and tested to be long lasting. The 8 cell battery can last up to 4 hours at a setting of 2 and the 16 cell battery can last up to 7 to 8 hours on a setting of 2 as well. The rechargeable batteries also have a quicker than normal recharge time at around 4 hours with the 8 cell battery and on the average of 6 hours for the 16 cell battery. The dimension of this unit are only 7.25 inches tall, 3 inches wide and 8.75 inches long; making it one of the smallest sized concentrator ever produced.

It is a pulse dose portable concentrator that operates on setting from 1 to 5 with oxygen concentration levels at around 90%. The machine is barely noticeable at only 39 decibels. It is so quiet that you can use it in a library or church without hearing it. It also features an easy to read LCD screen that displays flow settings and battery life.

It is FAA Approved for usage during flights and can be used on most cruise ships and buses. This makes it as a truly ideal solution for travel far and near!

  1. Thank You for providing a great device!

    Posted by Cindy F. on Apr 20th 2016

    I have had a Inogen One G3, for the past two years and i have to have it to leave the house. It sits right on the console in the car, on the floor next to me. I can plug it directly into the cigarette lighter or power port and i can keep the battery charged all day! I did have to have purchased a couple of extra batteries, as when we go to see my daughter it's a 4 hour flight i need more juice. Thank You for providing a great device!

  2. Great for Travel

    Posted by K Mitchle on Apr 17th 2016

    I purchased my first portable oxygen concentrator, however it was not an Inogen G3 and it failed me once too often. Just weeks before a scheduled 7 hour flight from Philadelphia to Denver, mine went down again and I had no Portable Concentrator! I had been told that Inogen G3 was considered the best POC on the market. I called the Portable Oxygen Store to inquire about it.
    After, a great responds from the knowledgeable staff, as well as a great price, I decided to buy it and I am so happy that I did. I found the Inogen One G3 to be easy to use, easy to care for and able to get me from Philadelphia to Denver, to visit the grand kids, without the need of changing batteries! And it was so quiet that I often checked to make sure the green light that signals that it is working was on!
    Thanks to Inogen, I can now look forward to more visits to see my grandchildren, without having to worry about how I am getting my next breath!

    The unit works exactly like advertised and we are more than completely satisfied with it! The service, knowledge and great friendly attitude of company employees we contacted prior to purchase were extremely helpful in explaining the unit and went overboard to make sure we had an complete answer for everything we asked. We received a great price on this from a fantastic organization.

  4. I am impressed!

    The Inogen One G3 is such a fantastic machine! A far comparison to what I was using prior to my purchase, my sleep has become improved and the noise reduction is dramatic and really appreciated.
    Won't never go back to the old stuff again.
    A big Thank You to the staff, at Portable Oxygen Store for help in choosing this model!
