Trunab Portable Oxygen Concentrator Backpack, Universal POC Bag with Adjustable Straps & Zippered Pockets Compatible with Inogen one, Caire Freestyle Comfort, Oxygo, Philips SimplyGo Mini (Grey)

Great for hauling around my oxygen concentrator without being too obvious. Plenty of room for extra batteries, hoses and charger as well as other things. Goid quality product.

Bought for husband. He likes that he can wear his concentrater on his back and it doesn't get in the way as he does outdoor chores.

The only thing that is not available. Some POC’s have the outlet of the Oxygen & the charge cord on the sides at the bottom of the unit. This requires cutting a hole in the vent material on each size.

See thru window not quite right location for Caire Free flow unit. Item is accommodating enough to be acceptable for it stated features.

Timely delivery. Fits my Inogen 5 perfect. Would buy again

It was very comfortable to wear however it caused my oxygen concentrator to overheat and shut down due to inadequate ventilation and as a result I suffered extremely from lack of oxygen before I could get home and get to my regular oxygen supply.

Got it for my oxygen tank my portable one
