New option for the amazing Inogen One G5 portable concentrator.  Works with the G3 too.

Adjustable lightweight cart specifically tailored to transport your Inogen One G3 or G5 hassle free and safely. For your convenience, the height level is 41″ high, but it fully collapses to 17.68″ for easy storage and transportation.  The cart only weighs 3.25 lbs/1.47 kg., but is rugged enough to roll over uneven surfaces with it’s wide wheel base and thick solid wheels.
