Got an answer for  Mary about Inogen One G2 Portable Oxygen Concentrator System?

Does the Inogen One G2 also have the Satellite Conserver that I saw described with the Inogen One? How does the conserver work? I currently use a Helios Liquid Oxygen system during the day (work) and it has a carrier bag that has both a shoulder strap and belt so that I can carry it hands free. Does the Inogen system have the same? I would like more information.?
