Actually, there seems to be complete lack of hand crank pumps that can do gas here. Also, when transfering large amounts, like from the gallon can to my 1.5litre bottle (I usually go flying with friends, so carrying a gas can every time is difficult), the electric pump is useful. I have a DB six-shooter pump that I had specifically bought for gas but my experience with the DB six shooters is not too good subsequently. There is no other reason to want to go to an electric pump other than lack of good hand crank gas pumps
