The Inogen One G2 is one of the lightest and most efficient portable models, for how powerful it is. As an oxygen concentrator, it filters the oxygen out of the air around it, which you can then breathe to receive the oxygen dosage that you need. This incredibly light and quiet FAA approved portable oxygen concentrator is less than 10 lbs, and easy to carry, which makes it a favorite for those who want to lead an active lifestyle.
The One G2 weighs 7 pounds, and that's with the 12 cell battery inside of it. It sits at 9.5 inches tall, 3.9 inches wide and 10.7 inches deep. With this size and weight, it's easy to carry around with the mobile cart, as well as across your shoulder. The carry bag and strap make it even more comfortable and convenient.
The oxygen dosage comes in a pulse dose, and the settings go from 1 to 6. The oxygen conserver is extremely sensitive for such a small portable oxygen concentrator, so you won't have to worry about not having enough oxygen when you need it the most, such as when your breath rate rises. You can always count on the pulse of oxygen to be delivered right on time.
The oxygen concentration output averages 93% on all settings, but goes no lower than 90%, with a maximum purity of 96%. When you turn it on, it only takes around 2 minutes to warm up before you can use it.
You have two options when it comes to battery power for the Inogen One G2 – the 12 cell battery, or the 24 cell battery. The 12 cell battery will last for as long as 4 hours, and the 24 cell can go as long as 8 hours on the lowest setting. Of course, you will have slightly less battery time on the higher settings. You can charge the battery and run it on AC or DC power at the same time. Charge it up at home, or in the car on your way to your destination.
You also won't have to worry about disturbing anyone with the noises being emitted from the One G2, as it releases oxygen. Unlike some large oxygen concentrators, it's noise has only been measured at 38 decibels at the most, which is as loud as a quiet conversation. You'll enjoy the low maintenance of the One G2, with the gross particle filter needing to be cleaned intermittently, and other filters needing to be replaced as needed.
The Inogen One G2 Starter Package includes the Inogen G2 unit, 12 cell battery, universal power supply, DC adapter, carry bag, cart, cannula, and manual.

I bought this item for my dad. We live in a very rural area and have to travel for doctor's appointments. I bought the Inogen with the 24 cell battery and he can pretty much go on a 200 mile trip and not even use half of the battery life. It is an awesome machine!!!! We are very happy with it. Way to go Brett, great sale!
Review by Stormy on 2/2/2016
My Inogen One was purchased about 8 years ago and I love it! It provides me with the freedom to get out and about without having to worry about running out of O₂. It comes with a house charger and a charger for your vehicle's lighter slot. You do not have to change tanks either. Just plug it in and charge up the battery unplug it and you're good to go for abut 8 hours on a full charge. I could go on and on about this machine but I won't. Did I mention that I love it!
Review by Edward Takala on 7/7/2015
Have had this machine for several years and love it. So does everyone that sees me use it.
Purchased with 2 24batteries and have never run out of ability to use. Have needed a few repairs at times. Use it with the pull behind cart so my ability to move around outside or in stores is uninhibited. This is great for me as even with COPD I'm a fast moving person.

Inogen One - G2
I have yet to see anyone address the problem of getting the unit in and out of an automobile. If you just have to do it once or twice a day, it's not too bad. However if you are out shopping at several stores getting the unit in and out of the auto, plus getting it in and out of shopping carts adds up and you will find yourself exhausted.
Another problem that I have encountered is putting the unit in the car and then taking the cannula off to get in the drivers seat and putting it back on. This, of course, happens every time I go to a different store.
Does anyone have any suggestions on these two big problems?

Wonderful oxygen concentrator overall. Life is so much more convenient now that I don't need to order more oxygen. Oxygen is all around us!
Review by Lucas V. on 7/11/2013
So much mobility
Fantastic life on just one battery. Go ahead and get the package with the extra battery, you won't regret it. This is just a really great oxygen concentrator in general.
Review by Lilja M. on 7/2/2013
Love the battery duration
Wonderful battery duration with this concentrator. I highly recommend getting the 24 cell battery. I can get 6 hours out of it with how much I use it.

Saving money now
I felt like I got so much more for my dollar already. Just two months ago I was using liquid oxygen tanks and now I don't have to order it.
Review by Bobby O. on 6/27/2013
I get more oxygen automatically if it senses that my breath rate went down. That's pretty good for such a small, light concentrator!

Product Q & A
How to change filter on the Inogen One G2?
The Inogen One G2 has a washable/external filter and an internal filter that need to be maintained. The washable/external filter is located on the back side of the machine and is a square shape made of a screen material. The gross particle filter should be rinsed off and completely dry before placing back into the machine. Depending on the number of hours the machine is used each day, the internal filter should be replaced every 1-2 years.
How do I perform a hard reset on the Inogen One G2?
To perform a hard reset, you will need to first remove the battery from the machine and disconnect all power to the unit. Let the machine sit powered down for 2 minutes. Plug the machine back into AC power (the power supply for use in the home) WITHOUT BATTERY and turn the machine on. Once the unit has been running for 5-10 minutes, place the battery into the machine WHILE RUNNING. This should eliminate the issue the machine is having. If the issue still occurs, call us and we will begin the process of creating a case.
How do I insert and remove the battery on the Inogen One G2?
The easiest way to insert and remove the battery is to have the machine standing upright. There is a small push down tab at the bottom of the machine. Press down on this tab, and then slide the battery away from the machine. When placing the battery inside the machine, make sure to slide it in gently. If you drop or slam the battery into the machine, the tabs or pc boards on the battery or the inside of the machine can be damaged or break. When removing the battery, you must press down on the battery tab then slide the battery away from the unit.
How long does the battery last at all settings on the Inogen One G2?
The battery duration FULLY CHARGED for Pulse Only up to the setting of 5. Keep in mind that battery durations are estimated because each patient has different breath rates and breathing patterns, which will make the batteries last for shorter or longer amounts of time. When you increase or decrease the settings, the charge per battery will either increase or decrease.
Settings 1-5 are rated for up to 4 hours of battery life. When you increase the settings from a 2 up to a 4, the battery will discharge at a faster rate.
Settings 1-5 are rated for up to 8 hours of battery life. When you increase the settings from a 2 up to a 4, the battery will discharge at a faster rate.
