Inogen One G2

Inogen One provides more independence for oxygen patients. This oxygen machine is designed to serve in multiple roles, including home oxygen, portable oxygen and travel oxygen. The G2 Concentrator is an advanced design and upgrade of the original Inogen One Concentrator for oxygen therapy patients. In comparison with the original, the Inogen One G2 is smaller in size and more lightweight. Weighing only 7.25 pounds, including the 12 cell battery, the Inogen One G2 Oxygen Concentrator is able to go where you need to go, when you need to go. It has a longer battery life between recharging--now up to 7 to 8 hours for the standard battery and up to 8 hours for the optional upgrade battery. An automotive adapter provides power and recharging while in route to your destinations, allowing you to shop, visit, and explore for extended periods. Purchasing additional batteries can extend your time away from power sources even longer.

Inogen One Concentrators are clinically proven to provide the necessary oxygen for most ambulatory patients during all phases of daily activity and during sleep. Compared with other major selling Portable Oxygen Concentrators, the Inogen One G2 Concentrator has one of the lightest weights on the market, even beating the Invacare XPO2 by .05 pounds. The Inogen One G2 also has an incredibly competitive and cost-effective price. In comparing sizes, this oxygen generator is the second smallest oxygen machine. Comparing sound emissions, the G2 emits the lowest decibels at only 38. The AC power supply is auto sensing to allow worldwide use. The G2 Oxygen Concentrator is authorized by the FAA for commercial airline travel, making the G2 a true Travel Oxygen Concentrator. The Inogen G2 Oxygen Concentrator provides greater independence than any other concentrator currently on the market.

Portable Oxygen Concentrator System Review
After being diagnosed with bronchitis, my life was never the same again. I frequently have to make sure that I lug around an oxygen concentrator when I travel for emergency. Before I had a system that is too big that I had to use a stroller so I can roll it easily. With Inogen One Portable Concentrator, that problem was solved. It's also great that it comes with a lithium battery which means that I can use it without plugging it. Really great for a traveler like me.

It changes quality of life
You might think it's too expensive and you don't need it because you can just breathe oxygen in the air not paying anything. That's kind of true but I want you to remember it's oxygen that makes you alive. I have had terrible chronic fatigue and no medication or vitamin could help me. Being always tired is just ruining your life. My doc advised me to breathe fresh air and this product is doing a great job for me. Definitely worth paying.

Well suited for her needs
First portable oxygen for wife was an Inogen One. We then bought another portable concentrator but it delivered only up to 3 LPM. We decided on the G2 because of greater battery life and lower weight than the Inogen One.
She's very happy with the new Inogen One G2 with the two, 24 cell batteries, which have been delivering 6 plus hours each at 4 LPM. She also likes the G2 because it's a few pounds lighter than the Inogen One. Additionally, the G2 seems to start more quickly than the Inogen One and other concentrator we bought.
By the way, we priced the G2 at two other sites and Vitality had the best price by more than $100.

Light and Quiet
Couple of weeks part-time use -- very pleased. Quiet enough I forget it's on, light enough to pack on my shoulder for a fairly brisk ten-minute walk -- well, brisk for an 80 year old. Have yet to recharge the 24-cell. It appears it'll go longer than 8 hours. Another feature: the audible alarm can be silenced -- a fault with a competing product whose squawking drove my wife nuts at night when my breathing was too shallow to register. Good price. Good machine.

I can Breath with Portable Oxygen
Ever since I received this I can actually go places again with my grandchildren. It is so easy to carry and lightweight. I love that it makes its own oxygen. This is great for the daytime and it even works at night when I need it. I love how small it is and easy to move it.

Good service on Inogen accessory
I ordered an adapter for my father to use and charge his Inogen One G2 while traveling in the car. It arrived in 7 days (5 days was the estimated time). It works well. Overall quite satisfied with the product and service.

Portable Oxygen is Better
Ever since receiving my Inogen One portable oxygen concentrator I get out more. I can just put carry the bag on my shoulder. When I had to use tanks it was such a pain to lug them around, I stayed home most of the time.
