Poor Quality Sign Two

Most of these strange low quality power banks has more than 8000mAh capacity but the USB output current is still only 1A. If manufacturer want to increase the capacity of Mobile power bank, they need to add batteries.

So, how could they treat the expensive batteries? Please carefully think this point.
