I use a wheeled carrier for my portable oxygen if for example I am going to a place where I will walking (i.e. mall).  I also use a backpack purse.  When going to the grocery store, I use the regular hand held carrier for my poc so that I can place it in the shopping cart.  When I use the wheeled carrier for my portable, I leave it in my car.  I switch from the regular hand held carrier when I reach my destination.  Hope this helps you.
