The utility model relates to a charged early-warning safety helmet which is formed by a charged early-warning device embedded in a safety helmet, wherein the charged early-warning device is composed of an induced voltage signal amplification circuit, a speech generator and an audio amplifying output circuit which are electrically connected sequentially. The charged early-warning safety helmet has a function of early warning whether scene objects are charged or not; when a safety helmet wearer is close to a charged object, the charged early-warning safety helmet can send a safety warning according to preset early-warning threshold values of voltage classes and distance, so that the safety helmet wearer can be prevented from getting an electric shock.
