TINY TIRE PUMP ACS - 120PSI Mini Electric Gauge Pump with Cool Taillight

I've tested it a bunch and it works great. The pump is the perfect size, quiet, and fast. The light is plenty bright and super useful. My only gripe is that the base for the light is pretty small and because the pump is cantilevered over it, it tends to bounce a lot. It uses a quarter turn mount similar to Garmin, but much smaller. I'm hoping additional mounting options are made available because it is awesome otherwise.

Small compact and very easy to attach to side of the bike.
