Review on 🔌 20PSI SUP Electric High Air Pump: Smart High Pressure Pump with Dual Stage & Auto-Off Function for Inflatables, Mattresses, Boats & Paddle Boards by Kenneth Mills

It worked as advertised. This morning I puffed them into two soups about 20 minutes apart. The first went to 15psi in about 12-15 minutes. The second started to hang at about 7psi and didn't maintain the same pace as the first. When I turned it off to check and maybe let it rest, I heard an air leak. Of course I didn't connect the air hose and nozzle tightly enough. I tightened it and turned it on. I finished up to 15psi in a very reasonable time. The "second stage” of the pump fires from 2 to 5 psi and then gets louder, which isn't too bad for normal daytime use, but wouldn't be desirable early in the morning on a quiet campground.
