摘要： A power adaption device includes an electrical cord assembly and an adaptor plug assembly. The adaptor plug assembly includes an electrical conduction member and a tightness adjustment member. The electrical conduction member is formed with an insertion hole and an adjustment hole in communication with each other. The electrical cord assembly is insertable into the insertion hole to electrically connect the electrical cord assembly with the electrical conduction member. The tightness adjustment member is screwed into and connected to the adjustment hole to abut the electrical cord assembly. As such, firmness of connection between the electrical cord assembly and the adaptor plug assembly can be enhanced.
