Portable Air Horn

Built for Power and Portability

BossHorn’s portable air horn pairs a high-output air compressor and real metal train horn trumpets with a custom control PCB for three selectable volume levels, motor overheat protection, and battery deep-discharge protection. The unit runs on compatible tool-brand batteries, works wirelessly up to 2,000 feet, and uses industrial-grade components salvaged from genuine cordless drills and impact drivers—hand-assembled in the USA for a robust, ready-to-use experience.

Ready Out of the Box — No Installation Needed

A portable air horn from BossHorn is plug-and-play: attach a compatible battery or buy a kit with one and you’re set. It feels solid in your hands, kicks with real sonic presence, and is ideal for tailgates, stadiums, farmwork, roadside safety, and outdoor event signaling. Expect quick starts, repeatable blasts, and the convenience of not mounting or wiring anything to your vehicle.
