Is it a pump or air compressor, it is 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, SmartHead™ DX3 w/ lower profile air release button to minimize unintended pressure release and stable base makes mounting tubeless and standard tires a breeze!
