This little gem isn't pretty to look at but it works great! It probably won't pump enough air into a tubeless tire to get it back on the rim on the open road, but neither will other pumps! It's a handy little pump to use when your tires are sagging. . It worked well for inflating the air shocks on my tow behind a Bushtec trailer. It comes with several different plugs to connect to your bike. For example battery clips, cigarette lighter sockets or two-wire polarized plugs. I have several of these for my bikes.
