declare the real capacity for all power banks we sell . Below steps will help you to caculate how many times you can charger your phone .
 
Number of charges equals = (Power capacity of Power Bank* battery conversion efficiency* phone inner core conversion efficiency (80%))/ the capacity of mobile phone battery

power bank conversion efficiency: 3.7V/5V
 
Phone inner core conversion efficiency: 80%
 
The capacity of phone battery: 1810 mAh
 
(5000mAhx 3.7/5*80%)/1810=1.6
 
So 5000mAh Power bank, the total Number of Charger of phone is about 1.5-2 times
