I own an inflatable kayak. By the time I have inflated it with the supplied handpump, I'm ready to take a short nap. I solved half of this problem by using my Ryobi high-volume/low-pressure inflator. The adapter presented here solves the rest of the problem by letting me connect my Ryobi low-volume/high-pressure inflator. It also has a pressure gauge to prevent over inflation.
This adapter can be made with a few hand tools and a drill press. Total cost is under $20.
