如何直接檢測行動電源的電容量？

Question

想請問一下如何檢測行動電源是否有足夠買所說的電容量？

最近買行動電源，但跟買的落差很大，

可是對方卻說是正常的，

電容量會落差30%左右，

再加上充電過程的快慢，還會影響行動電源的流量，

所以想直接對行動電源做檢測。

Answer 1

It is not practical to do so.

The most accurate method is to check its discharge time. But that means you will have to buy equipment for that, which can cost as much as a new power bank.

Battery capacity varies over time, due to battery quality, usage, etc.

So if you want high-quality power banks, choose major brands.

Answer 2

用放電電流乘時間便可以知道，例如電流是1000mA可以放一個鐘頭，容量就是1000mAH
