using on duckies. Want something electric to use initially and then something good for taking on the river (K pump?)

Need it for inflatable SUP that I just got. The pump that came with it is going to be a pain in the butt for my wife to use so need the electric (and I wouldn't mind using myself:). Looks like smaller K pumps are more streamlined than the one I have. It is more like a short/fat bicycle pump so the handle and the foot T makes it look like a pain to carry with you on the river.
