In Product description:

Large battery capacity 15000mAh (3.2V/48Wh) charge your phone up to 3 times, making it perfect for extended use on the go. Rated capacity 8000mAh (5V/3A). (When the voltage changes from 3.2V to 5V, the battery capacity loss is 20%)

This conversion is also true of lithium ion at 3.7v. All power banks that run on lithium ion advertise their capacity at 3.7v.

That's because most people don't understand mah ratings. They see a mah number on their power meter and it doesn't match what is listed on the battery device they are testing and they claim fraud. For capacity of a battery you need to know both MAH and VOLTAGE.
The power bank probably is as they cliam a 15000 mah battery.

Nice surprise to see that, the product's own video on Amazon doesn't show it so I wonder if it's a mix & unpredictable. Screenshot from the vid:
