In terms of electric pumps no 'air movement' pump with a simple fan can give more than paddling pool pressure - these are all the cheaper ones - only a specific compressor type with a piston (ie the Bravo type) will get you higher pressures.
Does depend how often you need to pump it up and your budget - if pumping it up and leaving it up all summer then a Bravo is not really needed and a camp shop stirrup pump is fine but for those who pack away each time the Bravo is a great investment.
Upshot is you either buy an HP Bravo to do the whole job or use a basic electric airbed type pump for the voume and a double action stirrup pump for the final pressure.
