    Answer: Don`t been calculated according to this way ,Power bank built-in 18650 electric battery core is3.7voltage,To charge cell phone voltage is 5v,So first to boost ,The conversion for 3.7/5 *20000=14800mAhafter boost.According to the use life to consider,The main board should reserve 20% of the electricity.Normally use that can charging 500 times cycles,If to charge at the empty situation ,The life will reduce by half .The available eletricty for 14800*0.8=11840mAh,Due to charge the cell phone ,That have 20% loss.That final charge the cell phone of 2000 capacity for 11840*0.8/2000=4.7times Special remind: Refuse any negative feedback about product quality after buy ,The product is Completely trustworthy ,The price is the lowest at the market
