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
