This pump is very small and lightweight but at the cost of being useless to inflate a tire sufficiently to be able to ride. I even had to do a lot of strokes just to partially inflate a tube before putting inside the tire. They fact that it says can go to more than 130 psi is a total joke, except maybe for the worlds strongest man.
This thing is so small and lightweight it seemed like a joke at first. The head does not lock on to the valve, but after learning how to hold it on the valve this pump actually works pretty good. With enough effort, this thing will get tires up to 100 psi or more. I've had a few flats since buying this pump and it fill up a tire as fast as any other mini pump I've used.
About the size of a whiteboard marker, weighs next to nothing, easily fits in a jersey pocket. The only real downside is the price.
Couldn't get over 20 psi.
Returned.
140 psi is a joke for any micro pump, but I have maybe 8 different ones
that achieve 60 psi without too much struggle.
Takes allot of pumping to fill 100 psi
Mounted on fat bike. Not usable on Schrader valves.
