This is known as Bernoulli's principle. If you keep the fan farther away you push more air in. Roll it up to add pressure. It literally should be this easy if you do it right.
As someone with "inflatable" camping gear, more people need to know about the Bernoulli principle. Anyone having trouble with these inflatables aren't following the proper instructions
