None. I bought it to inflate a couple of regular inflatables with the 12v version. In general the quality is good, I like the cable and the plug. BUT. The nozzle included in the kit is pointed, absolutely does not fit the usual inflatable pump that is standard on most swimming toys. (A type of nozzle which is a somewhat transparent soft plastic that is pulled out and then the attached cap removed.) The Coleman fitting is too thick to fit the nozzle. Also, it can't get deep enough into the toy's nozzle to open the flap of the one-way valve. So I will use it for an air bed but I will buy another module for swimming toys.
