    I really like my Freestyle portable concentrator. I am only giving it 4 stars because I wish the internal battery lasted a little longer for my needs.

  9. Travel Oxygen You Can Use

    Posted by Unknown on 28th Jun 2013

    For convenient travel oxygen, this is a pretty good concentrator to use. It's pulse-only, so if you need continuous oxygen settings, this is not for you. But it weighs less than five pounds, which is pretty astonishing for the quality of this oxygen concentrator. The universal power supply ensures that you'll always be able to plug in and charge up. This concentrator really enabled me to get out and experience the world.
