Well, inflation options depends where you are headed and how you'll get there. My float tube destinations are tyically 10 to 20 miles from the nearest parking spot--and in wilderness that prohibits entry other than on foot or horseback. I go on foot, so 12V or batteries are not an option--just too heavy. IF you fish the wilderness and need a very handy and very light pump, nothing beats the Coghlans double action air pump. Cost $5 or $6, if you can find one. They are no longer made, but they are still on the shelves in some stores. An alternative--Google search for pumps to inflate baloons. these are also light, double action pumps, but don't know how reliable.
