스마트폰용 일반 휴대용 파워뱅크로 배터리가 방전된 자동차를 점프스타트할 수 있는지 궁금함. 올바른 커넥터(예: 클램프)가 있으면 모든 파워뱅크가 가능한지, 아니면 자동차 점프스타트에 필요한 특정 요구사항(용량, 전용 설계 등)이 있는지 확인 필요
아니다, 불가능하다. 자동차 배터리는 12V에서 수백 암페어의 큰 전류가 필요한데, 일반 USB 출력은 5V에서 0.5A~2A 정도만 공급한다. 물 호스에 비유하면 암페어는 호스의 굵기, 볼트는 물의 흐름 속도다. 스마트폰 파워뱅크는 빨대 같은 호스에 미약한 물흐름이고, 자동차 배터리는 하수도 본관 수준의 굵은 호스에 강한 흐름이 필요하다는 뜻이다. 더 큰 문제는 충전 회로 설계에 따라 역방향 전기 흐름이 발생할 수 있다는 것이다. 즉, 자동차 배터리에서 파워뱅크로 전압과 전류가 역으로 흐르면서 충전기가 손상되거나 더 심각한 문제가 발생할 수 있다. 빨대를 하수도 본관에 연결했을 때 물을 틀면 무슨 일이 일어날지 생각해보면 된다. 참고: 일부 자동차 전용 점프스타트 파워뱅크 제품들이 있으며, 이러한 제품들의 리뷰는 대체로 긍정적이지만 작동하지 않는다는 리뷰도 일부 있다.

Go woke go broke. What's the point of Jaguars USP when any old Chinese EV maker can give you a super smooth 500bhp car with effortless torque and eery refinement for under £50 grand? When Tesla gives you much the same with the added benefit of a luxury charging network? Would it just be beauty?That's about the only thing they could possibly conjure as a point of difference but I doubt they can comply with a myriad of technical parameters for a global car AND make something gorgeous looking. The only way of making something quite different would be to not package the battery as a skateboard
