It depends on the voltage of the power supply. If it is 5V, 10000mA=10A, that is 5X10=50W, 1000wh= one degree of electricity, that is only 0.05 degrees. Generally speaking, the cell of the mobile power supply and the mobile phone battery are 3.7V, 10000MAHX3.7V=37WH, the loss of the charger and the mobile power management line accounts for about 50%, so according to the actual power consumption of 75WH, that is, 0.075 degrees of electricity, 1 degree of electricity can be charged more than a dozen times.
