  1. Recommend!

    Needed a portable oxygen concentrators with a powerful battery and high flow settings as I travel a lot and need reliable oxygen therapy on the go. This one is quiet enough, is light and comes with a nice battery. And came nicely packaged. Highly recommend the guys and gals at cpap europe for the kind assistance they all provided!!

    not a big fan of Inogen because of their prices but had no choice – needed a heavy-duty portable model that can do the trick and this one did more great. Arrived quickly as well

  3. Leonie

    What I like about the Inogen g5 is its weight, the looks and the Inogen Connect app which monitors battery life and provides useful notifications.
    My current battery lasts up to 13 hours, which is something I haven’t seen in previous o2 machines on the market
