Portable 20W megaphone with 400m range

The 5 Core 138 RU megaphone delivers 20 watts of output so your voice carries up to 400 meters. A built-in siren, recording and playback functions add flexibility for announcements or emergencies. Rechargeable battery power and a carrying strap keep the unit ready for mobile use. Ergonomic grip and lightweight construction suit indoor and outdoor crowds.

Replaces shouting or smaller PA units

This bullhorn upgrades any situation where unamplified speech cannot reach the audience or where a basic hand-held speaker lacks range. The jump is worth it when you need the siren alarm, voice recording, or the 400-meter projection for safety drills, sports coaching, or event control. Fire officers, teachers, and organizers gain a single device that covers both routine paging and emergency alerts.

Check battery workflow and mounting needs

Verify that the rechargeable battery cycle fits your event schedule so the megaphone stays powered through long sessions. Confirm the carrying strap attachment works with your preferred carrying style, whether over the shoulder or clipped to gear. Ensure the siren volume control meets local noise regulations for the venues you operate in.
