Battery Unit	Battery Notion	May 28, 2021	Alan Jo	Alan Jo	May 28, 2021		문제는 전류량 단위인 mAh(밀리암페어)를 전력량 단위인 와트시(Wh)로 바로 변환하여 볼 수 없다는 점이다. Wh는 전류량 x 전압으로 표현한 것이고, mAh는 전압은 상관없이 전류값만으로 표현한 것이기 때문에 mAh에 적힌 숫자를 그대로 Wh로 볼 수 없다. 만약 mAh를 Wh 단위로 정확하게 바꾸어 보려면 기기의 소비전력을 알아야만 한다. 하지만 그 계산이 몹시 어렵지는 않다. 보조배터리 용량에 스마트폰의 전압을 곱하고 그 값을 1000으로 나누면 Wh를 도출해낼 수 있다. 휴대폰용 보조배터리의 경우 휴대폰 배터리의 전압이 일반적으로 3.8V이므로 mAh에 3.8V를 곱하여 Wh 계산하면 된다. 참고로 배터리의 전압을 3.8V로 가정했을 때 대략적인 보조배터리의 용량은 다음과 같다. 20000mAh x 3.8V = 76000 = 76Wh 26318mAhx 3.8V = 100000 = 100Wh 42105mAhx 3.8V = 160000 = 160Wh > [[항공기 수하물 규정] 핸드폰 샤오미 보조배터리(리튬이온 배터리)를 비행기에 가지고 탈 수 있을까](https://m.blog.naver.com/PostView.nhn?blogId=vina2006&logNo=220929217780&proxyReferer=https%3A%2F%2Fwww.google.com%2F)	616e995661464812a978b2ea8a313d06

문제는 전류량 단위인 mAh(밀리암페어)를 전력량 단위인 와트시(Wh)로 바로 변환하여 볼 수 없다는 점이다. Wh는 전류량 x 전압으로 표현한 것이고, mAh는 전압은 상관없이 전류값만으로 표현한 것이기 때문에 mAh에 적힌 숫자를 그대로 Wh로 볼 수 없다. 만약 mAh를 Wh 단위로 정확하게 바꾸어 보려면 기기의 소비전력을 알아야만 한다. 하지만 그 계산이 몹시 어렵지는 않다. 보조배터리 용량에 스마트폰의 전압을 곱하고 그 값을 1000으로 나누면 Wh를 도출해낼 수 있다. 휴대폰용 보조배터리의 경우 휴대폰 배터리의 전압이 일반적으로 3.8V이므로 mAh에 3.8V를 곱하여 Wh 계산하면 된다. 참고로 배터리의 전압을 3.8V로 가정했을 때 대략적인 보조배터리의 용량은 다음과 같다. 20000mAh x 3.8V = 76000 = 76Wh 26318mAhx 3.8V = 100000 = 100Wh 42105mAhx 3.8V = 160000 = 160Wh > [[항공기 수하물 규정] 핸드폰 샤오미 보조배터리(리튬이온 배터리)를 비행기에 가지고 탈 수 있을까](https://m.blog.naver.com/PostView.nhn?blogId=vina2006&logNo=220929217780&proxyReferer=https%3A%2F%2Fwww.google.com%2F)
