The handle and cranking lever of this air raid siren are designed to fold, ensuring compact portability. Notably, the device requires no power supply, making it versatile and convenient to use. Producing a powerful, universally recognized sound, this manual, hand-crank-operated siren can generate a loud, adjustable volume of up to 110 decibels.

Crafted from durable aluminium alloy, the siren is built to withstand the rigors of various applications. It is ideal for capturing people's attention, cheering on favorite sports teams, and a wide range of other uses where a loud, effective warning signal is needed, particularly in situations where electricity is unavailable.
