The laws of physics can't be violated. "Rated" pressure of a tire pump is what the manufacturer wants you to think. "Real" pressure has to do with barrel diameter and how hard you are able to push the handle.
The nice thing about a Road Morph is that it's really a minerature floor pump. It has a hose so you're less likely to tear out your valve stem and it allows you to use your torso weight to help push the handle down.
