I personally wouldn't buy the 5 or 8 inch fans. We bought the 8 inch one from Walmart and it simply didn't push enough air...we took it back after opening it up and giving it a first try. A couple of years ago, we bought the 10 inch one from walmart and loved it. It had a swing out handle on top with a built in hook. It worked great to hand in an open window with the hook. We like the fact that we can use it on AC when on shore power, and on DC when boondocking. The 8 D cells are heavy, but run the fan for a considerable amount of time.
Hold out for the 10 inch fan. Some bigger walmarts sell a 10 inch version under the Ozark Trail brand name, but it does NOT come with the AC adapter, so you will go through many D cells, even when you have shore power. We did find a good 10 inch model of O2 Cool at Menard's and bought it, although it was about $6 more expensive. It does have the AC adapter, unfortunately it doesn't have the built in hook for hanging in a window. Ah, well....can't have everything.
