Inogen Cart

Designed for use with the Inogen One G3, Inogen One G5, and Inogen Rove 6 portable oxygen concentrators. It can also be used with the Philips Respironics SimplyGo Mini Portable Oxygen Concentrator.
The cart itself is a lightweight 3.25 lbs (1.47 kg).
The adjustable, telescopic handle extends to a height of 41 inches. Some sources mention two height levels: 34" and 41".
For storage and travel, the cart collapses to a compact 17.68 inches in height.
It features a wide wheelbase with thick, solid, heavy-duty wheels (some sources specify 5-inch wheels) designed for stability and smooth movement over various surfaces, including uneven terrain.
The concentrator unit can be easily secured to the cart, often by sliding a leather hook elastic at the back of the concentrator's carry bag over the handle, depending on the model. The cart allows the concentrator to stand upright and securely when stationary, without tipping over.
