-Question: Why does Power Bank have no print capacity(mAh)?
-Answer: If we printing capacity, the product can not be allowed to transport by the plane, we hope you can understand this.
There is no way in hell that pack is physically large enough to contain 500,000mAh (500 Ah).
In fact the battery pack itself is labelled 238.5WH:
At about 4V, this implies 60Ah, which is still complete codswallop.
6Ah would be closer to the mark.
And that is the real reason they don't mark the capacity on them - if they tell the truth then they can't compete with the other scammers, and if they print their outrageous lies, they can't ship the battery by air.
