Topeak JoeBlow Booster

Half air compressor - Half pump. The JoeBlow® Booster pump just made it easier to install tubeless tires. This pump has an integrated aluminum air chamber that stores an air charge of one liter, up to 160psi / 11 bar, to quickly fill your tire and ensure the proper installation on a tubeless rim, just like a shop compressor. Once you flip the selector from “CHARGE'' to “INFLATE'' mode, air bypasses the chamber and flows directly into your tire like a standard pump. The top-mounted easy to read gauge, air release button and comfortable dual density polymer grip, combined with its extra-long hose and stable base makes mounting tubeless and standard tires a breeze!
