I have not found any small pump able to achieve >80psi and doubt it is possible. That being said this pump is the best of the ones I have owned, very small, light, and has a built in valve stem tightener which is great since they often loosen up due to the screw on hose attachment.
I bought this pump as an impulse purchase due the size of the pump being easily fit in my jersey pocket. What was a unexpected benefit was how easily it attached to the valve stem and could be removed when pumping was completed. The pump also delivers good volume per stroke. Would recommend and buy again.
