Portable Air Horn Kit Solutions

Engineered Loudness & Reliable Components

Our air horn kit pairs a high-output air compressor with real metal train horn trumpets and a custom control PCB. You get three selectable volume levels, motor overheat protection, and battery deep-discharge protection built in. The control system supports wireless triggering up to 2,000 feet and works with batteries from 15+ major tool brands. Hand-assembled in the U.S., each kit uses industrial-grade fittings and a compact compressor designed to deliver consistent blasts without vehicle mounting.

Ready Out of the Box, No Mounting Needed

This air horn kit arrives fully assembled and ready to run—just attach a compatible cordless battery or buy the kit with battery included. It’s ideal for quick roadside signaling, event marshals who need a loud, portable siren, and off-roaders who want instant attention without drilling holes. Expect solid metal tones, simple wireless pairing, and run-times that match your battery capacity for predictable use.

Why Portability Matters

Looking for a long-range cordless air horn kit that works with Milwaukee batteries?

BossHorn started by rethinking cordless tool power for sound.

We hand-assemble every unit in the U.S.

We use real drill and impact-driver components where they matter.

Our custom PCB protects the motor and battery, so it lasts longer.

We’ve tested these horns in real-world scenarios—farm gates, trailers, and open trails.

The air horn kit brings professional-grade volume without installation, so you can carry it to the job, the field, or the campsite and trigger it from hundreds of yards away. The metal trumpets deliver a clear, cutting tone while the compressor and control board handle safety features like overheat and low-battery shutdown.
