Query: "B" adapter tips don't seem to be usable with this dual cable

I bought the ultraportable Kensington auto/air/wall charger at the same time as I bought this dual charging cable. None of the tips that come with the auto/air charger -- all of which are the "B" variations -- will fit on this dual cable, apparently by design. Same for the "winder" extension cable. I'm not sure if buying the non-"B" tips would solve the problem.
