Title: Had to make an adapter
Review: It would not fit any of my three differently branded air mattresses. One was a Coleman brand. They really should test a product before selling it. It also seemed to pump slower than my foot pump. Mine may have been defective - after five minutes of rigorous pumping my queen 6" mattress was only half full. I returned it because I had to use the hose from my other pump connected inline to get it to fit the air hole on my mattresses - which looked like a clusterpuff. Fairly useless - you may get lucky and it could inflate yours, but I wouldn't depend on it.
