Inogen makes my life so much easier, living in a northern rural area where power outages come often and hyways are closed sometimes for days. Just going for supplies is an hour plus drive that had to be rushed because of only 4 or 5 hrs in my portable tank. Heaven forbid if there was a waiting time at the Doctor's and a possible road closure.I just wouldn't go. Now I go. Inogen changed that drastically for me no worries now I have long battery life and can even charge it I'm the car. Going anywhere is so much more relaxing. Win win Inogen!!

I like it because it’s compact it lasts enough can charger in your car you can charge it in a plane I bought it for a battery the only problem with it is is that to carry the battery in the charger charger little heavy but all in all it’s a great unit and has provided me with plenty of oxygen

When I first needed oxygen 24/7, I insisted I have an oxygen concentrator to take with me when I needed to leave the big concentrator at home. They (Medicare) attempted to push me to using oxygen tanks. That couldn't work for me. I'm small, and not that strong. When I finally received a portable oxygen concentrator, it turned out to be more than 10 lbs! It was the only brand available to me from Medicare. I wasn't at all happy. I decided to purchase my own portable oxygen concentrator. I already knew I wanted an Inogen because I'd seen really good reviews and knew a couple of people who used them. I was so lucky to have as my representative, Dane Burton. He helped me put it all together, explained the information I needed, and made such a difference in my life. I'm so grateful for Inogen, and it's splendid representative, Dane.

The Imogen has allowed me more mobility and it is very light. I couldn’t be happier.
