Number of charges equals = (Power capacity of Power Bank* battery conversion efficiency* phone inner core conversion efficiency (75%))/ the capacity of mobile phone battery

Take iPhone6 for example:
Capacity of Power Bank: 15000mah
power bank conversion efficiency: 3.7V/5V
Phone inner core conversion efficiency: 75%
The capacity of iPhone6 battery: 1810 mAh
